This dataset contains monthly-averaged land surface temperatures (LST) and their uncertainty estimates from the Spinning Enhanced Visible and Infrared Imager (SEVIRI) onboard the Meteosat Second Generation series (Meteosat 8 - 11, also known as MSG1-4). The original surface temperatures are generated every hour, and in this L3C dataset are provided as monthly averages and distributed on a regular latitude-longitude grid with a resolution of 0.05ºx0.05º. The coverage is limited to land surfaces within the MSG disk, which encompasses Europe, Africa and part of South America.

LSTs are estimated from infrared measurements using a split-window algorithm and, therefore, are only available under clear-sky conditions.

The dataset was produced by the Portuguese Institute for Sea and Atmosphere (IPMA) as part of the ESA Land Surface Temperature Climate Change Initiative. The reader is referred to the LST_cci website for more information about how the data record was derived, and how to use the data and associated quality flags and estimated uncertainty.
