Ground Temperature Map, 2000-2017, Antarctic

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

The product provides modeled mean annual ground temperatures (MAGT) at the top of the permafrost for Antarctica and Subantarctic islands 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. Borehole temperature data from 35 boreholes were used to validate the Antarctic permafrost product and yielded a RMSE of 1.9 °C.

Modeled ground temperature data is also available for the Northern Hemisphere, the Andes, New Zealand, and the East African Plateau.

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