COMET is a homogeneous satellite-based cloud fraction climate data record covering Europe, Africa, parts of South America as well as the surrounding ocean areas back to 1991. Based on inter-calibrated radiances from Meteosat First and Second Generation satellites, the data record has an excellent decadal stability of less than 1%. It is therefore of particular interest to study climate variability of cloud cover. COMET is a characterized by comparability to SYNOP-based long-term cloud fraction observations carried out at WMO ground stations and can be used to supplement ground-based cloud fraction estimates in areas with low station density or high spatio-temporal cloud variability. COMET cloud fractions are provided as hourly, daily and monthly composites with a 0.05° to 0.05° spatial resolution from 1991 to 2015. The data record is available free of charge via the CM SAF Web User Interface and is provided in a user friendly NetCDF data format.
Along with the data, a comprehensive documentation including user guide, algorithm descriptions and extensive validation studies, is given
