The product provides modeled mean annual ground temperatures (MAGT) at the top of the permafrost for the Northern Hemisphere at 1 km spatial resolution. Permafrost probability (fraction values from 0 to 1) is assigned to each grid cell with MAGT < 0°C. Based on its permafrost probability each grid cell is classified as continuous, discontinuous and sporadic permafrost. The processing extent covers exposed land areas of the Northern Hemisphere down to 25 ° latitude. The mean MAGT was validated with GTN-P and TSP borehole ground temperature data and yielded a RMS of 2.0 °C. According to the results, permafrost (MAGT < 0 °C) covers 15 % of exposed land of the Northern Hemisphere.Following files are provided in geotiff format:- Mean Annual Ground Temperature (MAGTM) [C°]- MAGT Standard Deviation (MAGTSTD) [C°]- Permafrost Probability Fraction (PERPROB) [Fraction, 0-1]Permafrost Zonation (PERZONES) is provided as ESRI shapefile.All files are provided in Arctic Polar Stereographic projection (EPSG:3995 WGS ...
