Introduction

This report articulates Earth observation priorities for the Human Health: Air Quality SBA based on an analysis of 55 publicly-available documents, including documents produced by Group on Earth Observations’ Member Countries and Participating Organizations.

GEO and Societal Benefit Areas

The Group on Earth Observations (GEO, www.earthobservations.org) is an intergovernmental organization working to improve the availability, access, and use of Earth observations to benefit society. GEO is coordinating efforts to build a Global Earth Observation System of Systems (GEOSS) . GEOSS builds on national, regional, and international observation systems to provide coordinated Earth observations from thousands of ground, airborne, and space-based instruments. GEO is focused on enhancing the development and use of Earth observations in nine Societal Benefit Areas (SBA): Agriculture, Biodiversity, Climate, Disasters, Ecosystems, Energy, Human Health, Water, Weather

GEO Task US-09-01a

The objective of GEO Task US-09-01a is to establish and conduct a process to identify critical Earth observation priorities within each Societal Benefit Area (SBA) and those common to the nine SBAs. Many countries and organizations have written reports, held workshops, sponsored projects, conducted surveys, and produced documents that specify Earth observation needs. In addition, researchers and practitioners have also identified and recommended key Earth observation needs in publications and peer-reviewed literature. Task US-09-01a focuses on compiling information on observation parameters from a representative sampling of these existing materials and analyzing across the materials to determine the priority observations.

Purpose of Report

The primary purpose of this report is to articulate the critical Earth observation priorities for the Human Health SBA, specifically Air Quality as it affects health and well-being. The Human Health SBA EO priorities are addressed by two additional reports: Infections Diseases and Aeroallergens within GEO Task US-0901a. The intent of the report is to describe the overall process and specific methodologies used to identify documents, analyze them, and to determine a set of Earth observation parameters and characteristics. The report describes the prioritization methodologies used to determine the priority Earth observations for this SBA. The report also provides information on key challenges faced, feedback on the process, and recommendations for process improvements.

The primary audience for this report is the GEO User Interface Committee (UIC), which is managing Task US-09-01a for GEO. The GEO UIC will use the results of this report in combination with reports from the other eight SBAs. The GEO UIC will perform a meta-analysis across all nine SBA reports to identify critical Earth observation priorities common to many of the SBAs. Based on the nine SBA reports, the GEO UIC will produce an overall Task US-09-01a report, including the common observations and recommendations for GEO processes to determine Earth observation priorities in the future. The report’s authors anticipate that the GEO Secretariat, Committees, Member Countries, Participating Organizations, Observers, Communities of Practice, and the communities associated with the Human Health and other SBAs are additional audiences for this report.

Scope of Report

This report addresses the Earth observation priorities for the Human Health SBA. In particular, this report addresseS the sub-area of Air Quality within the Human Health SBA (see Section 3 for more details). The report provides some background and contextual information about Air Quality and Health. However, this report is not intended as a handbook or primer on Air Quality and Health, and a complete description of the Human Health SBA is beyond the scope of this report. Please consult the GEO website (http://www.earthobservations.org) for more information about the Human Health SBA.

The report focuses on the Earth observations for Air Quality and Health, independent of any specific technology or collection method. Thus, the report addresses the “demand” side of observation needs and priorities. It does not address the specific source of the observations or the sensor technology involved with producing the observations. Similarly, any discussions of visualization tools, decision support tools, or system processing characteristics (e.g., data format, data outlet) associated with the direct use of the observations are beyond the scope of this report.

The term Earth observation (EO) refers to parameters and variables (e.g., physical, geophysical, chemical, biological) sensed or measured, derived parameters and products, and related parameters from model outputs. The term Earth observation priorities refers to the parameters deemed of higher significance that others for the given SBA, as determined through the methodologies described within. The report uses the terms “user needs” and “user requirements” interchangeably to refer to Earth observations that are articulated and desired by the groups and users in the cited documents. The term “requirements” is used generally in the report to reflect users’ wants and needs and does not imply technical, engineering specifications.

Following this introduction, the report discusses the overall approach and methodologies used in this analysis (Section 2). Section 3 describes the Human Health SBA and the specific sub-areas. Section 4 articulates the specific Earth observations on Air Quality for Human Health and well-being. Section 5 presents the priority observations for Air Quality and Health. Sections 6 & 7 present additional findings from the analysis of the documents and any recommendations. The Appendices include the documents cited as well as additional information describing aspects of Air Quality and Human Health and Welfare.

Earth Observations: Types and Quality

Earth observations have many facets and require a range of attributes for a full characterization and description for the AQ SBA. The natural dimensions of EOs are the the measured parameters as well as the spatial and temporal extent. Each physical dimension is also characterized by the resolution of the observation, i.e. spatial and temporal resolution, and the possible grouping/lumping of the measured parameters.

Hardly any of the EOs can be used directly as raw data for decision making. Value adding processes (data filtering, aggregation and fusion) are needed to derive decision-ready products. The complementary use of EOS with air quality models is particularly important given the model’s potential to characterize multiple pollutant species across variable spatial and temporal scales. The more difficult characterization of EOs is along the value chain from the raw observed data to the derived information and knowledge that is used for decision making. Typical derived parameters include the air pollution index (an aggregate of multiple air pollutant concentrations), that informs the public on the general level of air pollution and facilitates personal decision making. Similarly, compliance with an AQ standard (derived from multi-year data series) informs an air quality manager whether an AQ control action is required. Other facets of EOs include relevancy to the application, data quality, tracability, timeliness, etc.

Methodology and Process

This section documents the general process followed and specific methodologies used to identify documents, analyze them, determine Earth observation parameters and characteristics, and establish a set of priority Earth observations for this SBA.

Task Process

The GEO UIC established a general process for each of the SBAs to follow in order to ensure some consistency across the SBAs. This general process for each SBA involves 9 steps, as summarized in the following list:

Step 1: Identify Analyst and Advisory Group for the SBA
Step 2: Determine scope of topics within the SBA
Step 3: Identify documents regarding observation priorities for the SBA
Step 4: Develop analytic methods and priority-setting criteria
Step 5: Review and analyze documents for priority Earth observations needs
Step 6: Combine the information and develop a preliminary report
Step 7: Gather feedback on the preliminary report
Step 8: Perform any additional analysis
Step 9: Complete the report on Earth observations for the SBA

A detailed description of the general US-09-01a process is available at the Task website http://sbageotask.larc.nasa.gov or GEO website. Some steps in the process occurred simultaneously or iteratively, such as identifying documents (Step 3) and reviewing documents (Step 5).

Analyst and Advisory Group

The Health and Air Quality group had an “Analyst” and an “Advisory Group” to conduct the process of identifying documents, analyzing them, and prioritizing the Earth observations. The Analyst served as the main coordinator to manage the activities.

Analysts

For Health and Air Quality, the Analysts were Rudolf Husar and Stefan Falke. He/she ... (brief paragraph on Analyst, including appropriate information to establish his/her credentials and qualifications as the Analyst).

The Health and Air Quality Analysts served ... (sentence/paragraph about the arrangement for the Analysts involvement (a pro bono basis as a representative of organization RRR, under contract to organization RRR, etc.)

Advisory Group

The first step in the nine-step GEO Task US-09-01a process is the formation of an expert Advisory Group (AG) that helps identify appropriate documents, provides feedback on the analysis approach and also reviews the preliminary and final reports. For the Air Quality and Health SBA, 17 potential AG members were identified. The sources of AG candidate names came from major Agency representatives, selections by the Analyst team, as well as additional AG candidates suggested by the AG members themselves. Ten of the invited candidates responded favorably and are listed in the Table below, two invitations were declined, three candidates did not respond and two candidates are still pending. Effort was made to include representatives from developing nations and to achieve a representation across geographic domains. Additional AG members would be desirable, particularly from the developing countries. The current AG is cordially invited to suggest additional candidates.

The Advisory Group for Health and Air Quality consisted of 12 experts from the field of Health and Air Quality or some subset thereof. Table X shows the Advisory Group members, including: Name, GEO Member Country or Participating Organization, Organizational Affiliation, Geographic Region, Specialty/Area of Expertise.

The Analyst identified the Advisory Group members through personal contacts, web searches. The Analyst attempted to recruit Advisory Group members from all geographic regions and multiple developing countries. The Analyst contacted #/numerous people to participate on the Advisory Group. # expressed interest; # did not respond; and # were unable to participate but provided document references or suggestions for other possible Advisory Group members. Overall, the Advisory Group includes members from 7 countries and 5 continents, including 3 from developing countries.

The primary roles of the AG were to (assist in identifying documents, assess methodologies and analytic techniques, assess prioritization schemes, review findings, and review reports.) The primary contact with the AG was thorugh (telecons, emails, etc.); the Advisory Group met (in person, telecom, etc) # number of times during the course of the analysis.

Other information about selection of AG, roles of AG.

Note: Comments on the success of the AG or suggestions how to improve the AG should be in section 7.

Methodology

This section provides a general description of the processes, analytic methods, and approaches the Analyst/AG used to identify documents, analyze them, and establish a set of priority Earth observations. (Note: this section is essentially a summary of your activities in Step 4 of the nine-step process.)

Documents

This section provides a general description of the process/method/approach the Analyst/AG used to identify documents and select a representative sampling for the analysis.

Task US-09-01a methodology required examination of a wide range of geographically distributed sources for potentially relevant, publicly available documents, including:

International, regional, and national documents focused on data sources, applications, or research priorities
Project reports (e.g., findings from major regional/national projects)
Surveys (e.g., of users of solar resource data)
Workshop and conference summaries
Individual peer-reviewed journal articles.

The Analyst used a 3-part methodology for identifying potentially relevant documents: (1) that were known to the Analysts group (2) documents suggested by the Advisory Group members to suggest (3) online searches. The documents provided by the AG contributed a broad range of perspectives as well as geographic coverage of developing countries. The online searches contributed relevant documents that were unknown to the Analysts or AG. These searches focused on the websites of international, regional, and national organizations engaged in Air Quality and Health. [Need table with examples of all 3] This 3-prong approach was used to ensure that the set of documents ultimately analyzed would have broad geographic distribution and represent both developed and developing countries. This resulted in an initial set of potentially relevant documents.

These documents include reports of regional workshops and assessments by national environmental agencies.

The online searches conducted by the Analyst focused on the websites of international, regional, and national organizations engaged in health and environment. The literature searches relied on standard library search tools using a variety of renewable energy key words. This twofold approach was used to ensure that the set of documents ultimately analyzed would have broad geographic distribution and represent both developed and developing countries.

The Analyst used a twofold methodology for identifying potentially relevant documents: (1) literature and online searches, and (2) requests for Advisory Group members to suggest documents. The Analyst emphasized to Advisory Group members that any documents suggested for analysis need to be publicly available. This resulted in an initial set of potentially relevant documents.

Upon further examination by the Analyst, each document had to include one of the following for consideration in the analysis: (1) specification of Earth observation parameters needed by users for renewable energy applications, or (2) reference to Earth observation parameters currently in use for renewable energy applications, with some indication of the adequacy of the parameter characteristics as currently available. While the Analyst focused initially on identifying the first type of document (identifying parameters needed by users), only a few of the identified documents fit neatly within this category. Thus, it was necessary to include the second type of document (focused on the adequacy of current observations) in order to have a broad enough set of documents from which priorities could be derived. A certain degree of specificity was required for a document to be deemed relevant for analysis. That is, the document had to name the specific parameter(s) required or used, along with at least some indication of parameter characteristics (e.g., spatial resolution), in order to be included in the analysis. The parameter characteristics that were sought are as follows:

Coverage/Extent
Spatial resolution (vertical and horizontal, as relevant)
Temporal resolution (frequency)
Timeliness (availability of measurement)
Accuracy/Precision.

Analytic Methods

This section provides a general description of the process/method/approach the Analyst/AG used to analyze documents and extract information to identify Earth observation parameters and characteristics.

For those documents identified in Section 2.3.1, the Analysts conducted a detailed data extraction process. The first round of extraction involved the documentation of region, doc type and parameters mentioned in the document. For each document a table was made to track the parameters and any mention of desired parameter characteristics such as: :

Coverage/Extent
Temporal resolution (frequency)
Spatial resolution (vertical and horizontal, as relevant)
Timeliness (availability of measurement)
Accuracy/Precision.

For better comparison and recording all mentioned Earth observation parameter information was added to a spreadsheet organized by parameter and document. Each row in the spreadsheet represented a document, and each column represented a EO parameter (e.g., ozone), facilitating a quick review of the total information gleaned, either by document or parameter.

The results of this categorization are shown later in Section 3.3. The Analyst then conducted a detailed data extraction process. This entailed reading or skimming the document for mention of Earth observations, and recording all mentioned Earth observation parameter information in a spreadsheet organized by parameter and document. Each row in the spreadsheet represented a document, and each column represented a parameter (e.g., wind speed), facilitating a quick review of the total information gleaned, either by document or parameter. The Analyst recorded all relevant information provided in the document, including any mention of desired parameter characteristics

Gaps

In cases where the information in the document referred to the adequacy of the characteristics of a current observation rather than the ideally required parameter characteristics, the parameter characteristics of the current observation were recorded for reference purposes. For example, if a document indicated that current spatial resolution of wind speed data is inadequate, the spatial resolution of the current observation referenced in the document, if specified, was recorded (such as on a 10km x 10km grid). While this information on adequacy of current observations does not provide an absolute target of ideally required parameter characteristics, this information was used to fill gaps where information was lacking on ideally required parameter characteristics. A distinction between the information derived from these two approaches is clearly made in the results section of this document.

Multiple Criteria

The next step was to construct a table of priority observations for each renewable energy subarea, as described in Section 3.2. To do this, the Analyst noted whether there were one or more documents for each sub-area that addressed ideally required user needs, as opposed to the adequacy of current observations. For solar and wind energy, such documents addressing ideally required user needs were available, and these “primary” documents were used as an initial basis to construct a priorities table for those sub-areas. The Analyst then compared the needs in these primary documents to parameters identified in other relevant documents, and added parameters to the table in cases that did not contradict the primary sources. Where there was a parameter that was indicated as important by three or more documents, but not the primary document, the Analyst included it in the table, but flagged such parameter as not derived from a primary user needs document.

The Analyst performed a detailed data extraction process on the documents that met the criteria for inclusion in the analysis. All of the data extracted were compiled into a single database for further analysis. For each observation, the extracted information included the applicable disaster type(s) (earthquake/landslide/flood), the region of interest of the document (Global/Africa/Europe/Oceania/Asia and the Middle East/East Asia/North America/South and Central America), the type of document (e.g., international working group report, peer-reviewed journal article, conference proceedings, etc.) and the desired physical characteristics of the observation, where applicable.

The aggregation of certain parameters that are similar in nature in this way provides a more robust analysis, since individual observation requirements may not be frequently identified in the documents, but the effect could be larger if the observation were to be considered at the aggregated level. For example, precipitation duration, precipitation intensity, and precipitation amount were combined into a single “precipitation” category that was carried forward into the prioritization analysis. For each of the disaster types, the Analyst constructed a table of the observation priorities, as well as the aggregated observation category, that were identified in at least one of the document references. References to the documents that explicitly identify each observation as a priority are also included in the tables.

Prioritization Methods

The analysts used three factors to prioritize the EO needs. The first was a bibliographic method to determine which pollutants were cited most. The second factor weighted the EOs for coverage and the third factor weighted the EOs for their potency (or how close they were to the actual cause of sickness). Aggregate Emission, transport ambient.

In this second step, the method for assigning priority used well-known bibliometric methods (OTA, 1986). Priority was indicated by the relative frequency with which an observation was cited by the documents as a required climate observation. For identifying global priorities, and using the master database of all required observations generated during the document review, a simple count was taken of the number of documents in which a particular Earth observation was described in the document as a required observation. This value was divided by the total number of documents in which global requirements are discussed.

For the regional priorities, the count was taken of the number of regions for which an observation was described as a priority (for example, the number of regions for which extreme precipitation observations is required). This value was divided by the total number of possible regions. Several of the documents describe requirements for multiple regions. Appendix C identifies reports containing regional information.

Weight	Definition	Example	Factor
Bibliographic	# of times param mentioned in literature	PM2.5 mentioned 21x	0-1
Coverage	spatial and temporal coverage	Need better coverage in Africa for PM2.5	0-1
Potency	How close the parameter is to the actual cause of sickness	PM10 is available, but not the actual source of sickness	0-1

Air Quality and Health

This section provides summary information of the Health and Air Quality and the specific sub-areas. This section also discusses the specific documents used in the meta-analysis (general discussion rather than specifics on each document) and the broad user-types within the SBA.

Uses and users of EOs for Air Quality and Health

Identifying the key users is a necessity for proper evaluation of their Earth Observation (EO) needs. In this report uses and user categories are represented in a two dimensional matrix. The first dimension is the end-use category. An end user uses the EO for making a personal or societal decision. We will consider three groups of end-users of air quality-relevant observations: general public, air quality managers, and air quality policy makers. Each end use group has different EO needs. The respective information needs for each end user category will be determined.

The second dimension of EO user classification is along the value chain that transforms the raw observations into suitable information for the decision-makers (end users). Data managers and data flow mediators are a class of users who are responsible for the timely, robust and proper flow of EOs to the SBA application. These users, can be considered part ot the GEO information infrastrucuture. Intermediate users include researchers, analysts, and modelers who digest and prepare the raw observations in a manner that is suitable for the end-user's decision making needs. The consumers of the processed EOs are the end-users listed above. Classifying users along the value adding chain would aid consistency with the GEOSS data sharing infrastructure, the right information is delivered to the right user. It is here recognized that public documents that explicitly address the information requirements for each user class in the 2D user matrix will be sparse.

Emphasis on quality control… at all stages of the data flow.

GEOSS will be a vital means of bringing useful environmental data to the health community in a user friendly form. Comprehensive data sets are powerful tools that support prevention, early warning, research, epidemiology, health care planning and delivery, and provide a variety of timely public alerts. For example, by linking weather, air quality data and the urban heat island effects, air quality forecasts can help protect asthmatics, the elderly and the young from cardiovascular and respiratory problems resulting from air pollution episodes. These data can also provide linkages to longer-term air quality impacts such as cancers, respiratory diseases, asthma and birth defects.

Description

Health: Understanding environmental factors affecting human health and well-being

Health issues with Earth observation needs include: airborne, marine, and water pollution; stratospheric ozone depletion; persistent organic pollutants; nutrition; and monitoring weather-related disease vectors. GEOSS will improve the flow of appropriate environmental data and health statistics to the health community promoting a focus on prevention and contributing to the continued improvements in human health worldwide.

The following is the brief statement of topics covered and key outcomes in the Health SBA from the GEOSS 10-Year Implementation Plan: Health issues with Earth-observation needs include: airborne, marine, and water pollution; stratospheric ozone depletion; persistent organic pollutants; nutrition; and monitoring weather-related disease vectors. GEOSS will improve the flow of appropriate environmental

Section 3.1 should briefly state the broad set of sub-areas within the SBA. For example, the Disasters report stated the broad categories of disasters (weather-related, geologic, and human-induced) and specific disaster types (earthquakes, volcanoes, wildfires, avalanches, etc.). Section 3.2 articulates the specific sub-areas the report addresses.

GEOSS 10-Year Plan Reference Document Pg. 43

Currently, the work being conducted with remote sensing technologies and disease is through interdisciplinary research groups involving scientists with varied backgrounds such as remote sensing, epidemiologists, and atmospheric scientists (e.g. the international ESSP). The science of epidemiology involves observing factors that might be associated with disease, and then calculating the degree of significance in the association. The true value of Earth Observation data will become more fully realized when simple, user-friendly data products are prepared that are easily overlaid onto disease/dysfunction maps. For example, if an epidemiologist wishes to investigate factors associated with childhood asthma, it will be useful to model the physical location of patients with real-time and cumulative local airborne particulates over the study period. GEOSS can make a significant contribution to this class of activity by ensuring data are available and developing the modelling capability.

Air Quality Sub-Areas

Earth Observations for Health and Air Quality are not uniformly distributed. For this report, the Analysts classified priority EOs for different geographic region using the physical breakdown shown in the table below. Earth Observations are needed at each stage from the emission of the pollutant to the population exposure.

AQ SubTypes	Brief Description

This section discusses the broad user types within the SBA. The specific user types can be listed or in a table. This section needs to describe how the user types were employed by the Analyst/AG, such as to perform a gap analysis of the documents to determine any potential biases.

GEOSS 10-Year Plan Reference Document Pg. 42

Health service providers, researchers, policy makers, and the public in developed and developing countries as well as indigenous communities need such data products for providing the services,science, and decisions that affect human health and well-being.

Earth Observations for Air Quality and Health

This section contains the results from the analysis of the documents and the specific observation parameters/characteristics that the analysis revealed for each sub-area.

GEOSS 10-Year Plan Reference Document Pg. 43

It will be achieved through the development of a system of in situ, airborne, and space-based systems integrated through assimilation and modelling tools with census data on health, and
GEOSS will be invaluable in allowing exposure and disease data to be related among populations. For example, the aerial particle pollution and health consequences among the World’s major cities could be compared and contrasted, and degenerating environmental conditions that could lead to the emergence of infectious diseases could be identified and reversed before a new epidemic occurs.
It is essential to be able to relate the results of disease studies conducted in different times and locations. Historical data from satellites on the effects of land use and land cover changes are needed to track, model and predict changes in ozone, particulate matter, chemical emissions, disease vectors, cancers, and birth defects to evaluate improvements in health conditions related to public well-being.

GEOSS 10-Year Plan Reference Document Pg. 201

Health issues with Earth-observation needs include: airborne, marine, and water pollution; stratospheric ozone depletion; persistent organic pollutants; nutrition; and monitoring weather-related disease vectors. GEOSS will improve the flow of appropriate environmental data and health statistics to the health community, promoting a focus on prevention and contributing to continued improvements in human health worldwide.

Emissions

These sections should state what observations and characteristics came out of the meta-analysis of the documents, including a brief rationale based on the documents. These sections need to reflect the methodology from 2.3.2. Essentially, the section for each sub-area needs to articulate which observations “made the cut” and why.

For each sub-area, this section should identify the observations mentioned in the documents and state the specific observations that are common and representative of the sub-area. This section should reference the documents in establishing the set of observations. Since the results should be based on the methodology described in section 2.3.2, this section should blend those methodologies into the discussion in this section. A table listing all the observations and representative characteristics in this sub-area would be beneficial – please use the template table that Lawrence provided in an email.
