Stefan Falke - History and Work of ESIP AQ Cluster/WG

Stefan Falke: Overview of ESIP AQWG - link to Stefan PPT

    • AQ Cluster has connected lots of data systems and programs, through efforts like DataFed
    • Need to figure out what’s still operational in this network
    • Timeline of AQ Cluster, AQWG, GEO AQCoP activity
    • ESIP Clusters meant to be short term. As interest and goals become longer term, AQ Cluster became AQWG
    • As AQWG, group involved with ESIP activities, governance, eligible for support, etc
    • Stefan ran logistics for AQWG during much of its history

Erin Robinson: The Role of ESIP

    • ESIP AQWG presented themselves to GEOSS as self-organized grouping
    • ESIP AQWG loaded in AQ datasets, built interoperable systems, contributed to best practices collection
    • Neutral space for coordination and interaction
    • Bringing together people at technical practitioner level
    • Support technical infrastructure for science applications
    • Provide virtual interaction as well as human interaction
    • ESIP critical to AQCoP functions

Rudy Husar: ‬Introduction to GEO AQ CoP

    • AQCoP Regional Clusters for North America, Europe, India
    • ESIP wiki provides workspace for AQWG & AQCoP
    • Tour of ESIP GEO AQCoP workspace
    • Goal is an interoperable AQ Data Network (ADN)
    • ADN Solta 2011 Meeting: connect the connectors to create a network
    • AQ Data Network (ADN)
    • DataFed, a node of ADN - is an implementation of the GEOSS data sharing paradigm

Martin Schultz European Perspectives on AQCoP; JOIN

(See Schultz presentation file)

  • AQCoP/ADN issues:
    • 1st meeting - Solta
    • 2nd meeting - Dublin
    • 3rd meeting - Mumbai
    • AQCoP mailing list – need to increase usage
    • Confusion on the European side about GEO AQCoP
    • Delineate better who is doing what, try to make that clear to EU folks
    • Continue series of workshops
    • Propose next workshop in Boulder this fall
  • JOIN – Jülich OWS Interface
    • ECCAD data served up – example overlay ACCMP and PAN data from model
    • JOIN is ready for users as of week of January 7
    • Jülich test system still available until end of month
    • Next steps for JOIN:
      • Restructuring and public release of core code – can port to ECCAD, IAGOS groups, CIERA
    • Support: MACC, IGAS (Toulouse IAGOS data), EPA, FZ Jülich, EU, HTAP
  • MACC requests of AQCoP (MACC = EU’s chemical forecasting effort):
    • Better user management
    • Direct linking to specific data sets and views
    • Consolidate metadata profile and publish metadata records – still working on best practice recommendations
  • HTAP requests of AQCoP (HTAP = intercontinental pollutant transport model intercomparison exercise):
    • Geneva meeting in mid-March
    • Linkage to server (new HTAP archive)
    • More model and data comparison tools

Claire GranierECCAD

  • ECCAD portal =
  • ECCAD delivers emission inventories and ancillary data
  • Ether – European Earth Science network
  • Links to Julich server
  • Making the data useful to a broad community, simple to use tools
  • Next steps:
    • Include more GHGs, toxics

Greg FrostEmissions Data Needs, Issues, and Interoperability from the GEIA Perspective

  • GEIA portal =
  • Motivation for improving emissions data
  • Overview of GEIA’s mission and goals
  • Examples of GEIA activities, including ECCAD ( and CIERA ( portals
  • GEIA relies heavily on its partnership with AQCoP
  • Scientific and technical needs for improving access and analysis of emissions data
  • Suggest changing name of GEO AQCoP to “Air Quality and Atmospheric Composition CoP”

Uma ShankarUNC/CMAS Efforts

(See Shankar presentation file)

  • Support EPA capabilities for regional chemical transport modeling and emissions
  • Perspective and needs for delivering data to EPA and other US regulatory entities
  • Engage groups who provide various data sets for emission modeling (land cover, etc) in AQCoP
    • Data are distributed all over the place, but not connected right now
  • CMAS carries out its efforts through work assignments
  • Modeling platforms from OAQPS and what’s being done in ORD are not well connected
  • Emission Modeling Framework database – Zac Adelman, Uma
    • EPA’s data could be made available through this database
  • Recommends not duplicating efforts, and keeping CMAS involved, especially due to limited resources on US side

Terry Keating Issues of interest to AQWG/AQCoP

  • Bringing satellite data into AirNow
  • HTAP
    • Example of why we need a GEOSS
    • Next meeting in Geneva, March 18-22, in conjunction with WMO’s 2013 conference
    • Details at
    • Objectives:
      • Establish science, evaluations, analyses to be done in HTAP
      • Status of information infrastructure that’s been created for HTAP
    • Could expand Martin Schultz group’s system built for HTAP Phase 1
    • Modeling resources:
      • Data at Julich and (AeroCom)
      • Ensemble system at JRC
      • Atmospheric Brown Cloud Asia
      • MICS Asia (Tokyo, China) – Asian modeling
      • RSIG – regional modeling exercises
    • Observations:
      • Surface – NILU (EBAS)
      • Aircraft – ATOM (NASA Langley)
      • Satellite – NASA GIOVANNI, Atmos Comp Portal
    • Emissions:
      • GEIA/CIERA – one platform to deliver HTAP emissions
      • ECCAD – another platform to deliver HTAP emissions; in process of modifying to accept information at higher resolution
    • Development of analysis tools that draw on these databases
      • Some work at DataFed, MACC to develop tools: this effort could be expanded
  • North American Commission on Environmental Cooperation Climate Information System
    • CEC involves US, Canada, Mexico
    • CEC had a scoping project about this – decided to focus on emissions
      • identified need for web services approach to delivering these data
    • 3 countries working on online database of GHG and BC emissions
    • Proposals due next week, select contractor by end of January, work done by end of July
    • Tri-national national-level database focused on GHGs, BC, and related emissions
    • Terry will connect contractor to AQCoP
  • AQCoP Governance
    • Wiki discussion initiated
    • Recommend defining co-chairs, secretariat, steering body


Name of AQCoP

  • Recommend that we include “Atmospheric Composition” in name
  • Need to let GEO know about this change
  • Alert ESIP?

AQCoP Governance

  • Possible telecon to formalize the governance - early February?
  • Need some governance in place before we call another meeting of the AQCoP
  • In addition to “top-down” structure, need “bottom up” governance
  • Need technical committee to deal with network issues: data catalog, metadata…
  • Perhaps defining these tasks as working groups?
  • High-level umbrella steering group necessary for strategic planning and to secure resources
  • Need improved forum for communication and coordination
  • Suggestion to nominate 2 interim chairs or conveners to help organize meetings and coordinate efforts

Proposed Agenda - Ann Keane & Community

Session1: January 10 8:30-10:00 GMT-5

  • Introduction to the GEO AQ CoP - Rudy Husar
  • Discussion of CoP Governance and issues raised during the session. To be continued in the second session.

Some of topics to cover might be:

  • what data is provided
  • what technologies are used
  • who is using the data for what
  • what difficulties have you encountered
  • what is needed for future development

Session2: January 10 10:30-12:00 GMT-5

This session will cover issues raised in the first session. Some potential topics:

  • Issues faced by modelers in accessing data services.
  • Issues of accessing data services
  • Issues of publishing data services
  • Existing metadata standards and conventions
  • Use cases for the existing services
  • Discussion of technologies for access to large data for various types of post-processing web services. The IRODS group may be presenting at ESIP as well.
  • How to proceed with metadata data developments started in Dublin.
  • Discussion of the next versions of WCS and DAP.
  • Data conventions for distributing point data.
  • Data catalog registration and search access. Does AQCoP need a faceted search i.e. [1]?

The goal of these two sessions will be to gain a better understanding of how the community is working and what work needs to be done to meet the broader scientific priorities.
