The ISCCP H-Series Climate Data Record consists of several parts: (1) ISCCP H-Series dataset, (2) ISCCP-Basic H-Series, and (3) Ancillary and input datasets. ISCCP H Series data The full ISCCP dataset consists of netCDF files containing various derived cloud parameters. The H-Series data includes several products. These include: * HXS (H-series pixel level single satellite - not in netcdf), * HXG (H-series pixel level gridded), * HGG (H-series Gridded Global), * HGH (H-series gridded monthly by hour), and * HGM ( H-series Gridded Monthly). The netCDF files are not structured with CF-standard names. Data variables are unitless and rely on data tables that are needed to represent each geophysical variable. Keeping ISCCP H-Series in this native format ensures that existing "power users" will be able to continue using the data. ISCCP Basic H Series ISCCP Basic files contains a subset of the cloud variables and products available in the full ISCCP dataset. It consists of remapped, calibrated, and subsetted variables following CF-conventions. In addition, the netCDF files follow full netCDF CF and ACDD Conventions. These files are intended to be use by new and/or less advanced users that may want to use cloud data, but do not need the full ISCCP dataset. Ancillary and Input data Ancillary and Input data used in the production of ISCCP are also archived. These consist of B1U geostationary satellite data, B1U and GAC calibration/HBT tables, and ancillary files for nnHIRS, AEROSOL, SNOWICE, and OZONE datasets. The resulting 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.

Internally-inconsistent retrievals are included in averages, so that total cloudiness and the amount of very high, optically thin clouds is overstated to an unknown degree. Approximately 10% of the planet is covered with partly cloudy pixels and many of these are treated as fully cloudy in ISCCP data, complicating comparisons with models.

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. Data are collected from an international suite of weather satellites and merged into the ISCCP Climate Data Record Product. ISCCP processes data from up to 5 geostationary satellites and 2 polar orbiters at 3-hourly and ~.1 deg temporal and spatial resolutions. The ISCCP analysis combines satellite-measured radiances with the TOVS atmospheric temperature-humidity and snow/ice correlative datasets to obtain information about clouds and the surface. The analysis method first determines the presence or absence of clouds in each individual image pixel and retrieves the radiometric properties of the cloud for each cloudy pixel and of the surface for each clear pixel. The pixel analysis is performed separately for each satellite radiance dataset and the results are reported in the HXS, and HXG data products which have a nominal resolution of ~10 km and 3 hr. The HGG product is produced by summarizing the pixel-level results every 3 hours on an equal-area map grid with 1 deg resolution and merging the results from separate satellites with the TV and S/I datasets to produce global coverage at each time. The HGH and HGM data products are produced by averaging HGG data over each month, first in each of eight 3-hour time intervals individually and then over all eight time intervals to produce a monthly average product.
