Ground Temperature Map, 2000-2016, Northern Hemisphere Permafrost

Obu, Jaroslav; Westermann, Sebastian; Kääb, Andreas; Bartsch, Annett

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 Northern Hemisphere down to 25 ° latitude. The mean MAGT was validated with GTN-P and TSP borehole ground temperature data yielded RMS of 2.0 °C. According to the results permafrost (MAGT < 0 °C) covers 15 % of exposed land of the Northern Hemisphere.

More Information about the modelling method can be found in the product guide.
