GEO-CAPE HQ Perspective and Workshop Charge

1. GEO-CAPE HQ Perspective and Workshop Charge GEO-CAPE Workshop Ken Jucks and Paula Bontempi August 18, 2008

2. GEO-CAPE Preliminary Science Steering Group • Randy Kawa, GSFC • Jack Fishman, LaRC • Janet Campbell, UNH • Curt Davis, Oregon St. • Chuck McClain, GSFC • Annmarie Eldering, JPL • Daniel Jacob, Harvard • Omar Torres, Hampton U. • Rich Scheffe, EPA • Primary responsibility is to serve as the Steering Committee for the August 2008 Science Definition and Planning Workshop. • The group may be refined or replaced as studies are initiated and mission planning matures. • The group is responsible to Ken Jucks and Paula Bontempi at NASA HQ, interacting with Ernie Hilsenrath, Hal Maring, David Considine, Fred Lipschultz, and Lawrence Friedl

3. Rationale Behind Agenda • Science questions first!!! (of course, this follows all the bureaucratic stuff like talks from HQ) • Community input and feedback is critical for ensuring the maximum science return from any satellite mission. • Open discussion is our chosen forum for defining the proper science questions that GEO-CAPE should attempt to address. • Past and planned satellite missions and potential technological approaches for an active mission comes next. • Aura, Envisat, Eumetsat • Other Decadal Survey missions (GACM, ACE) • Multiple IIP concepts and Sentinel missions • Steps to move GEO-CAPE forward. • Traceability (science questions to measurements to observation requirements) • Identify tasks (e.g. modeling and field studies) to help prepare for the first phase of development. • Identify technology gaps and necessary studies to support paths forward. • Identify infrastructure from current/planned missions that need further development for GEO-CAPE.

4. Goals for the GEO-CAPE Workshop • Concise and clear definition of critical science questions in Air Quality and Coastal Ocean Biology & Chemistry that can and would be addressed from geosynchronous orbit observations. • Development of observations needed to address the science questions. • Discussion of inter or the cross discipline science the mission could or should address. • Start to define the traceability from science to instrumentation. • Information exchange regarding the various prototype instruments and their potential contributions toward a GEO-CAPE platform that could address the science and measurement requirements. • List of how the potential data from GEO-CAPE would be applied by operational agencies (e.g. EPA and NOAA). • List of all tasks needed in the next 18 months based on technology gaps, modeling studies, etc. that will more clearly define the science traceability matrix.

5. GEO-CAPE FY08 - FY09 Study Schedule • August 18-20, 2008 Community Workshop • Workshop report November 1, 2008 • Science and measurement requirements as a basis for FY 2009 studies. • Prioritized list of studies. • Beginning in early FY 2009, initiate recommended studies, potentially including, but not limited to: • OSSE’s to clarify and refine measurement & mission requirements. • Studies to improve the ability to remotely sense boundary layer O3. • Instrument concept studies. • Investigations of options for atmospheric profiling, if needed • Field campaigns to further mature existing ESTO funded instruments and to provide data for algorithm development studies. • Beginning in late FY 2009: • Follow-up IMDC or Team-X mission concept study.
