The International Satellite Cloud Climatology Project (ISCCP) was based at the Goddard Institute for Space Studies in New York. ISCCP was sponsored by the World Climate Research Programme for the purpose of "collecting and analyzing satellite radiance measurements to infer the global distribution of cloud radiative properties and their diurnal and seasonal variations". This dataset collection contains the global three-hourly cloud products (ISCCP-D1), global monthly cloud products (ISCCP-D2), using the revised algorithm, at 280 km spatial resolution and and monthly cloud analysis products (ISCCP-C2) at 250 km spatial resolution. There are more than 200 variables contained within the datasets. Note - that that the temporal range of the datasets presented here are contain data available from the NASA Atmospheric Science Data Center (ASDC) covers the full extent available at the time of the dataset publication in the CEDA archives, begin in July 1983 and extend through to December 1999 (D1), 2006 (D2) and 1990 (C1). Fuller versions of the datasets are available from ASDC directly. These limited copies were obtained to aid researcher access within the UK community at the time.

ISCCP was sponsored by the World Climate Research Programme for the purpose of "collecting and analysing satellite radiance measurements to infer the global distribution of cloud radiative properties and their diurnal and seasonal variations". This dataset contains the global monthly cloud analysis products (ISCCP-C2), at 250 km spatial resolution. They are derived from monthly averages of data taken with three-hour resolution. The products include monthly averages of calibrated radiances, cloud detection results, and cloud and surface properties from radiative analysis. There are 72 variables contained within the data set. The data available at the time of publication begin in July 1983 and extend through December 1990.
