Aerosol effects on the cloud optical depth retrieval from atmospheric transmittance

Among the cloud properties, cloud optical depth is particularly useful to describe the cloud, and can be determined from surface measurements of the total atmospheric transmittance in some shortwave bands. Here we use a very simple two-stream treatment of the radiative transfer to show how cloud opt...
