In order to obtain aerosol optical depth (AOD) from a satellite, you need to choose a spectral band with very little gaseous absorption so the scattering due to the aerosols present in the at- mosphere is apparent. Radiance measured from all four spectral channels used on the Mul- ti-angle Imaging SpectroRadiometer (MISR) can be used to find AOD. Radiance can then be converted to aerosol optical depth using a form of Beer’s Law. The MISR channels are centered around 446 (blue), 558 (green), 672 (red), and 867 (near-in-

Cloud screening is also import-ant when obtaining aerosol properties. The presence of clouds will affect the measured radiance and it will not be representative of the aerosol present in that part of the atmosphere. Image from: Kim Chamales MPO 551...
