Land Surface Temperature Dataset from Meteosat First and Second Generation - Edition 1 (SUMET Ed. 1)

This Thematic Climate Data Record (TCDR) provides Land Surface Temperature (LST) derived from the Meteosat Visible and InfraRed Imager (MVIRI) on board the Meteosat First Generation (MFG) and the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) onboard the Meteosat Second Generation (MSG) satellites. The covered time period ranges from January 1991 to December 2015, thus includes MFG 4 to 7 and MSG 1 to 3. Original thermal radiances were inter-calibrated by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) using the High Resolution Infrared Radiation Sounder (HIRS) as a reference. The LST is derived from Meteosat by use of single-channel LST retrieval algorithms suitable to generate LST data across Meteosat satellite generations. This TCDR includes two different LST products: the Statistical Land Surface Temperature product generated with a statistical LST retrieval approach and a Physical Land Surface Temperature product based on radiative transfer calculations. The LST is presented as hourly data and as monthly averaged diurnal cycle composites on a 0.05°x0.05° grid covering the entire Meteosat disk (Africa and Europe). A summary of the retrieval algorithms is provided by Duguay–Tetzlaff et al. 2015. Along with the data, a comprehensive documentation including user guide, algorithm descriptions and extensive validation studies, is given.
