NO2 Workshop

back to NO2 Synthesis page

---

Objective:

Assemble air pollution monitoring scientists (satellite and surface sensor data producers), information scientists and technology developers, and air quality researchers and managers to begin defining guidelines and best practices in creating web networks and applications that use satellite and surface data for assessment, analysis and modeling of air quality. For purposes of framing the discussion, the group will focus on NO2 monitoring, analysis, modeling and applications.

Desired Outcomes:

1. identify and organize, through online methods, available NO2 data and information resources
2. develop guidelines and blueprints for improving use of NO2 data in air quality research and management, including advancing initial demonstrations of prototype NO2 web applications
3. define cross-organization, cross-project activities to undertake with NO2 data and web networks and explore related opportunities to advance other air quality activities

November 1
8:30-10:30 Roundtable: How to improve future AQ applications using satellite and surface data

• how to establish connections among data/algorithm producers, data providers, web infrastructure mediators, and end users.
• clarify appropriate application and interpretation of the NO2 products
• define key assumptions, restrictions, caveats, etc. that need to be captured along with data (e.g., data lineage)
• identify gaps between what is currently provided and what is needed
• determine what can be done by each group (data producers, IT developers, and AQ researchers/managers) to create a network for building better applications.
• Challenges/obstacles scientists are facing in understanding NO2 data

10:30-11:00 Break
11:00-12:30 Next steps in developing networked elements and applications

• How can we leverage the NO2 work as a pathfinder to accelerate our collective capacity to use data from new platforms such as the Orbiting Carbon Observatory (OCO) targeted for launch in 2008 or NPOESS?
