The Seven SouthEast Asian Studies (7-SEAS) Mission has been established to characterize aerosol-meteorological interactions from Java through the Malay Peninsula and Southeast Asia to Taiwan. The 7-SEAS program was organized through a collaborative effort with the U.S. State Department and governments in Southeast Asia, NCAR Research Applications Laboratory, NASA Aerosol Robotic Network (AERONET) program, and the Office of Naval Research international field offices. The 7-SEAS mission will utilize collaborator assets to develop ground-based instrumentation networks, remotely-sensed and model data sets, and perform intensive in situ measurements by air, land and sea. The 7-SEAS region from the tropics to subtropics has significant gradients in air pollution varying from near pristine to heavily-polluted atmospheric conditions providing a unique natural laboratory for atmospheric measurements. These atmospheric measurements will improve scientific understanding in clouds and precipitation, radiative transfer, calibration/validation, anthropogenic and biomass burning emissions and transport, natural background atmospheric chemistry, tropical and subtropical meteorology, and regional nowcasting, forecasting and inter-annual outlooks.
