  1. Earth Science Missions and Opportunities for the Atmospheric Chemistry and Dynamics Branch Mark Schoeberl

  2. Missions and HQ • There appears to be a lot of confusion at HQ about new missions • Mike Freilich wants to stick to the Decadal Survey (DS) mission set • Some new money to begin work on Phase A for IceSat II and SMAP • NASA studies suggest that DS mission costs are too low by 1.5-2x • Griffin is openly hostile to doing Earth Science missions because it would take money from Exploration • Stern (from the planetary side) can’t understand why we are so expensive - GSFC is responding to this. • Lost of pressure from everywhere to have NASA do more Earth Science • Change in Administration will probably help • What are our instrument strengths • UV-Vis (ACAM, Geo-Spec) • What else can we do? • OSSE’s for Geo or Leo missions • Need to define the goal of the OSSE • Simulate what the instrument will see • Determine if the information useful for assimilation • Figure out what else needs to be measured

  3. Decadal Survey Missions & Venture Class Other NPOESS mission opportunities…

  4. NAS Missions

  5. Mission Type: Decadal Survey, mid time frame Mission Lead: GSFC Mission Goals: Sources, transport, and chemistry of atmospheric pollution Coastal ocean dynamics and biophysics Notional Payload: Medium-resolution (7 km) scanning UV-Vis spectrometer Very high-resolution (300 m) programmable UV-Vis-NIR imager CO imager in reflected sunlight and thermal emission Key Themes: Target processes occur rapidly at small scales: 1-3 hour sampling. Terrestrial biosphere objectives should be included. Very high-resolution, geosynchronous multi-disciplinary observatory is a shared resource for regular observations, special observing studies, and emergencies. Status: HQ mission studies (GeoMAC and integrated #5) done Cost: $0.55 to 1.3B Launch: 2013-2016 Contact: Competition/collaboration: Langley - competing for atmos. component JPL - compete for hi-res (ocean) imager? CSA- provide CO detector? Center Support (IRAD’08): Optics and detector testing; pointing system design study; science requirements definition. HQ Support: Workshop/working group being discussed Next Steps/Issues: Mission too expensive Explore GeoQuikRide Refine discipline requirements Science Leads: Kawa, Janz, Pickering, Mannino, Middleton, Bhartia, Gleason, Rodriguez 8ºx8º Geostationary Coastal and Air Pollution Events Mission (GEO-CAPE)

  6. Mission Type: Decadal Survey (2016-2020) Mission Lead: GSFC Instruments #1 a/o 2 (below) could be built at GSFC Mission Goals: Ozone Recovery Intercontinental transport of pollution Notional Payload: Limb-viewing Microwave Spectrometer (JPL) UV/VIS Spectrometer (GSFC) SWIR & TIR Spectrometer (Lockheed) Key Themes: Use the limb instrument to study the upper troposphere and the stratosphere. Use UV/VIS to study to study O3, SO2, NO2, HCHO and aerosols. O3 and HCHO measurements may be enhanced by using SWIR/TIR channels. Use SWIR/TIR to study CO. Status: HQ mission studies considered both SSO and non-SSO Cost: $1B+ Launch: 2018 Contact: P. K. Bhartia ( Competition/collaboration: JPL - TES team is designing a interferometer to cover UV to TIR bands. KNMI/NL- may provide UV/VIS instrument CSA - may provide the CO instrument Center Support (IRAD’08): Design of a high spatial resolution UV/VIS spectrometer to determine plume height by stereo viewing. HQ Support: HQ POC - Jucks, Hilsenrath Next Steps/Issues: Mission too expensive explore using limb IR instrument instead of limb-microwave or keeping microwave vertical resolution same as Aura/MLS Mission Science Definition Team: Herman, Joiner, Chance, Torres, Krotkov, Gleason, Duncan, Pickering, Janz, Livesy, Jacob Global Atmospheric Composition Mission Mission (GACM) NO2 over India

  14. Who’s working on what

  15. Summary • Lots of mission opportunities • DS near term focus on GEO • Geo-CAPE - issues with Langley • Opprotunity for LEO instruments less clear • NPOESS • Climate mission 1 • GACM • Need to spread the work around a little
