220 – Retrievals and Analyses of Global Aerosol Properties
Principal Investigator(s): S-H. Wang
Aerosols affect Earth’s energy budget by scattering and absorbing radiation (the “direct effect”) and by modifying microphysical and radiative properties of clouds (the “indirect effect”). The complex spatial, temporal, chemical composition, physical size and shape, and optical characteristics of atmospheric aerosols cause large uncertainties in the estimation of aerosol effects on climate. To lessen the uncertainties, remote sensing and in-situ measurements as observational approach providing essential information. The NASA/GSFC SMART-COMMIT (Surface-sensing Measurements for Atmospheric Radiative Transfer – Chemical, Optical, and Microphysical Measurement of In-situ Troposphere) mobile observatory has conducted more than 10 worldwide field campaigns in the past 10 years. The surface remote sensing and in-situ technologies were applied to study aerosol properties using SMART-COMMIT database. We integrate surface radiation measurement, satellites data, and radiative transfer model to understand the global aerosol properties and regional radiative impact of aerosols.
