Global Aerosol Climatology Project (GACP) was established in 1998 as
part of the Global Energy and Water Cycle Experiment (GEWEX). Its main
objective is to analyze satellite radiance measurements and field
observations to infer the global distribution of aerosols, their
properties, and their seasonal and interannual variations. The
resulting datasets and analysis products will be used to improve
understanding and modeling of the climate forcing due to changing
aerosols, including both the direct radiative forcing by the aerosols
and the indirect radiative forcing caused by effects of changing
aerosols on cloud properties.

The first dataset available is a model-derived aerosol optical
thickness data set. The data are monthly mean values of the aerosol
optical thickness derived from chemistry transport models.

Space Studies (GISS) to retrieve the data and to view additional
documentation.
