  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. 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, 2008 - 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 • http://vista.cira.colostate.edu/AirDataWiki/ROSES2007.ashx • 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 • Finalize design of system enhancements: 2008 • Integrate satellite data and implement data portals: 2008-09 • Implementation of advanced analysis tools: 2009-10 • Second project workshop and begin beta testing: 2010 • Integrate model evaluation tools and test with CMAQ outputs: 2010-11 • Final demonstration workshop and report: 2011
