Theoretical and experimental research is under way in atmospheric science, radiative transfer, and remote sensing. This research focuses on (1) remote sensing of aerosols and clouds; (2) atmospheric correction of satellite imagery of the Earth's surface; (3) interaction of aerosols and clouds, and their climatic impact; (4) remote sensing of emissions from biomass burning in the tropics; (5) calibration of satellite sensors using the Earth's atmosphere and surface reflectance; and (6) analysis of satellite data. Field experiments are conducted with measurements from aircraft and from the ground of the aerosol properties (e.g., smoke aerosol, dust, and anthropogenic aerosol), and their effect on cloud microphysics and radiation characteristics.
