Community Radiative Transfer Model
Given an atmospheric profile of temperature, variable gas concentrations, cloud and surface properties CRTM calculates radiances and brightness temperatures. The only mandatory input is water vapor and ozone. The range of temperatures and water vapour concentrations over which the optical depth computations are valid depends on the training datasets which were used.
