Land Surface Temperature (LST) is the radiative skin temperature over land. LST plays an important role in the physics of land surface as it is involved in the processes of energy and water exchange with the atmosphere. LST is useful for the scientific community, namely for those dealing with meteorological and climate models. Accurate values of LST are also of special interest in a wide range of areas related to land surface processes, including meteorology, hydrology, agrometeorology, climatology and environmental studies. Land Surface Emissivity (EM), a crucial parameter for LST retrieval from space, is independently estimated as a function of (satellite derived) Fraction of Vegetation Cover (FVC) and land cover classification.
The characteristics and file format of this demonstration Data Record are the same as its correspondent NRT product. Thus documented by the common Algorithm Theoretical Basis Document (ATBD), Product User Manual document (PUM) and Product Output Format document (POF) documents. The validation results for this Data Record are available in the (VR) document.

The MSG mission (in operations since 2004) already provides a relatively long time series of VIS and IR observations over the full Earth Disk centred at 0º. The full archive of MSG/SEVIRI data was reprocessed to provide the user comunity a consistent, homogeneous and continuous Data Record of the 15-min Land Surface Temperature (LST) for the period 2004-2015.
This Data Record was obtained with the best version of its equivalent NRT product (MLST) which can also complement the time series from 2016 onwards.
