1. NASA ROSES 2007:
Decision Support through Earth Science Research Results
Improving an Air Quality Decision Support System through the Integration of Satellite Data
with Ground-based, Modeled, and Emissions Data
Project Update 10/21/2008: Cooperative Institute for Research in the Atmosphere

2. Specific Project Goals
Overall Project Goal
To enhance and add value to a currently operational air quality decision support system (VIEWS/TSS) by integrating and utilizing satellite data from NASA satellites Aura, Terra, Aqua, and CALIPSO.
Specific Project Goals
Develop routine capture, analysis, and processing algorithms with high temporal and spatial resolution to provide land use/land cover data as inputs to emissions and air quality modeling
Achieve more complete temporal and spatial resolution of activity data and emission rates from natural and anthropogenic emission sources in remote areas and from individual sources and source clusters
Obtain multiple-dimensional vertical profiles and column measurements of pollutants to improve model inputs and provide evaluation data for gridded chemistry-transport models such as CMAQ
Develop advanced analysis tools to better understand the relevant atmospheric processes and their representation in the CTMs
Visualize and analyze satellite data in combination with existing monitoring, emissions, and modeling data within a unified decision support platform

3. Activities So Far
Conducted a project design workshop (May 12-13, CIRA)
Discussed and refined project scope
Created a project steering committee composed of end user representatives
Created a “wiki” website for project communications and document-sharing
Participated in the EPA’s Air Quality Data Summit (February 2008, RTP)
Presented an overview of the VIEWS/TSS decision support system
Explored parallel efforts being conducted by other organizations
Suggested best practices for air quality data exchange and decision support
Attended the GEOSS Architecture Implementation Workshop (NCAR)
Presented an overview of VIEWS/TSS and the NASA ROSES project
Determined the GEOSS architectural standards to be implemented for future interoperability with other air quality data- and decision-support systems
Investigated the available and relevant satellite data and products to be integrated into VIEWS/TSS

4. Next Steps: Source Data Acquisition

5. Next Steps: Source Data Extraction (What do we need?)
Observation time
Latitude, longitude, and elevation
Spacecraft attitude
Solar and viewing angles
Relevant data fields
Ground pixel quality flags
Measurement quality flags
Other flags: Fit Quality, AMF Quality, Unpolled Field Quality, VCD Quality
Collection and Inventory Metadata

6. Next Steps: Source Data Reduction (How much do we need?)

7. Next Steps: Source Data Preprocessing

8. Next Steps: Database Extension and Enhancement

9. Future Steps: Enhancement and development of end user tools

10. Schedule and Deliverables
