Solar radiation enters the Earth's atmosphere with a portion being scattered by clouds and aerosols.

If I know the aerosol compositional model identifier, how can I get information about the corresponding aerosol model?

To obtain the complete information about the aerosol models, you will need to order the MISR Aerosol Climatology Product (MIANACP) which contains the Aerosol Physical and Optical Properties (APOP) and the Mixture files. The Mixture file lists the pure particles in each model identifier. The APOP then gives the detailed information for the pure particles. More information on the MISR aerosol model is available from the MISR publications page and the Algorithm Theoretical Basis Document (ATBD).
