| contents | 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 84). More Information about the modelling method can be found in the product guide. The map was produced within the project ESA Data User Element GlobPermafrost. Dataset update: 2019-04-01 |
