Abstract
This record comprises 17 years (1995-2012) of global cloud observations from the Along Track Scanning Radiometer (ATSR) series of instruments, flown on board the ESA Earth Observation satellites (ERS-2) and Envisat. The data is provided as monthly 0.5 x 0.5 degree, and daily 0.1x0.1 degree, longitude-latitude averages containing fractional cloud coverage (the percentage of each grid cell covered by cloud), cloud-top height, cloud optical depth, effective radius and liquid/ice water paths, along with uncertainties for each parameter.
This dataset is a re-gridded version of the European Space Agency (ESA) Climate Change Initiative version 3.0 cloud product (Cloud_cci) produced to meet the requirements for distribution through the Copernicus Climate Change Service (C3S). Full details of the dataset, include data-quality and validation information can be found via the C3S Climate Data Store (CDS).
