  1. Southeast Asia Composition, Cloud, Climate Coupling Regional Study(SEAC4RS) A NASA / NSF / NRL airborne field campaign focusing on atmospheric composition, chemistry, and climate over Southeast Asia. Programmatic Context, Issues and Outlook Anticipated deployment period: August - September 2012 http://espo.nasa.gov/missions/seac4rs

  2. SEAC4RS Programmatic Objectives • Science • Gas and aerosol surface emissions transport in convection • Atmospheric processes in convection • Atmospheric particle effects on weather and climate • Satellite Calibration and Validation • Aircraft measurements will enable the improvement of satellite measurements • Improved satellite measurements will be useful for climate research, weather forecasting, land cover studies, … • Satellite Prototype Instrument Testing (i.e, polarimeters) • Fly airborne simulators of next generation satellite sensors • Provide new science data

  3. SEAC4RS Programmatic Issues • Combining Science – Cal/Val – Prototype Testing will compromise the output of the project • Possibly true for a single objective, but not true in the big picture • Even the progress toward a single objective may be enhanced in the longer-term by the combination of these objectives • Large Multi-platform, Multi-objective Campaigns are less efficient, scientifically, than a tightly focused, single aircraft project • Possibly true for some specificscientific questions • Advances in Earth System Science (e.g., climate) usually require a broad observational perspective both in terms of the variety of measurements as well as space and time frame (i.e., combine multiple airborne platforms, surface-based and satellite observations) • We need to take on these large projects because we can

  4. SEAC4RS Education and Public Outreach • Satellite and AERONET/MPLNET Data Utilization Short Courses • Training: • utilization of NASA Earth Science data for research • utilization of NPP direct broadcast • AERONET data utilization? • Location: Utapao or University or Thai Agency? • Pre-Deployment Media Telecon • Visits to SEAC4RS at Naval Air Station • Media Day • VIP Tours • School Children Tours (security?) • Talks given by SEAC4RS Scientists • Location: Universities and/or Agencies • Level: Expert and/or General Interest

  5. Aircraft Platforms • NASA ER-2: Upper Troposphere to Lower Stratosphere • Cruise altitude 18-21 km, range 3000 nmi, endurance 8-10 h • Payload: Emphasis on remote sensing of aerosols and radiation with capability to observe basic chemical tracers • NSF/NCAR GV: Mid-to-Upper Troposphere • Ceiling 14 km, range 4000 nmi, endurance 8-10 h • Payload: Emphasis on detailed atmospheric composition and photochemistry for gases and aerosols as well as cloud microphysics • NASA DC-8: Surface to Upper Troposphere • Ceiling 12 km, range 4000 nmi, endurance 8-10 h • Payload: Emphasis on detailed atmospheric composition and photochemistry for gases and aerosols, detailed radiation measurements, and remote sensing of ozone and aerosols • BRRAA King Air 350: Surface to Upper Troposphere • Ceiling 10 km, range 1700 nmi, endurance 6 h • Payload: Emphasis on in-situ measurements of cloud particle concentration and microphysics as well as aerosol and cloud condensation nucleus concentration and microphysics
