This product from EOS-6 OCM-3 Sensor operated in Global Area Coverage (GAC) mode provides Aerosol Optical Depth (AOD) at 870 nm derived from one scene of a global coverage (2days) at a spatial resolution of 1.1km. This product quantifies the concentration of atmospheric aerosols - such as dust, smoke, and pollution - that scatter and absorb sunlight in a vertical column of the atmosphere. AOD is crucial for atmospheric correction of other geophysical data products and for studying the climatic impacts of aerosols.
