Its interface is extremely flexible and easy to use. There are 24 shortwave and 105 longwave bands.
Gas absorption is parameterized with overlapping gases.
Gaseous absorption may be turned on or off. Liquid and ice cloud optical properties, five aerosol optical models, and four aerosol vertical profiles are part of the model database. Clouds may be specified as some combination of particle size, water content, optical and geometrical thicknesses, or the optical properties and phase function can be input. There are seven standard atmospheric profiles. Standard profiles include tropical, mid-latitude, subarctic, and arctic.
