Users should not use ISCCP D-Series except in rare cases (e.g., when reproducing previous studies that used the ISCCP D-Series).** ISCCP was established in 1982 as part of the World Climate Research Programme (WCRP) to collect and analyze satellite radiance measurements to infer the global distribution of clouds, their properties, and their diurnal, seasonal, and interannual variations. Period of record is July 1, 1983 through December 31, 2009. ISCCP D-Series dataset consists of the following products: (1) D1 - Cloud products gridded to 2.5 deg at 3 hourly time steps. This includes about 200 variables, including cloud products, ancillary data and static data. (2) D2 - Monthly averages of cloud products gridded to 2.5 degree. This includes many variables and processing inputs (e.g., ancillary data) as well as outputs (cloud products, etc.). D2 data are temporal averages of the D1 data. (3) DX - Pixel level cloud products in the satellite-projection. This data is roughly 32 km and 3 hourly. This data is used to derive the D1 product. In addition, there are ancillary data files included with the archive; these inputs that are used to create the D-series data. The ISCCP datasets and analysis products are being used to improve understanding and modeling of the role of clouds in climate, with the primary focus being the elucidation of the effects of clouds on the radiation balance. These data can also used to support many other cloud studies, including understanding of the hydrological cycle.

Data sub-sampling The source satellite data is subsampled from the full resolution (as received at the Satellite Processing Center, SPC) to B2 data [B2 refers to a subsampling that approximates a spatial resolution ~32 km). Data processing capabilities in the 1980s could not handle transferring or processing full resolution data, so sub sampled data was sent for archive at the ISCCP Central Archive (NOAA NCEI) and processing at the ISCCP Global Processing Center (NASA GISS). Numerous SPCs provided B2 data throughout the ISCCP history. This includes: Canada (AES & MSC), the University of Wisconsin (UWS), Colorado State University (CSU), NOAA (NOA), Europe (EUM and ESA), and Japan (JMA). processor n/a. Each SPC developed its own sub sampling software. Data intercalibration SPCs also sent satellite data to the ISCCP Global Calibration Center (France). The GCC prepared calibration information that allowed direct comparisons between visible and infrared channels on AVHRR with similar channels on the various Geostationary satellites. GCC provided normalization coefficients to the GPC processor Normalization and calibration of geostationary satellite radiances for ISCCP Desormeaux, Y., W.B. Rossow, C.L. Brest, and C.G.
