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

SEAC 4 RS 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

SEAC 4 RS 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 specific scientific 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

SEAC 4 RS 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?
