Ground Temperature Map, 2000-2016, Northern Hemisphere Permafrost

Original data information: 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.

The map was produced within the project ESA Data User Element
GlobPermafrost.

QGreenland displays data at 10 km resolution.
