A new map of permafrost distribution on the Tibetan Plateau (2017)

The Tibetan Plateau (TP) has the largest areas of permafrost terrain in the mid- and low-latitude regions of the world. Some permafrost distribution maps have been compiled but, due to limited data sources, ambiguous criteria, inadequate validation, and deficiency of high-quality spatial data sets, there is high uncertainty in the mapping of the permafrost distribution on the TP.

We generated a new permafrost map based on freezing and thawing indices from modified Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperatures (LSTs)、The temperature at the top of permafrost (TTOP) model was applied to simulate the permafrost distribution , validated this map using various ground-based data sets.

The properties of frozen soil include: Seasonally frozen ground、Permafrost、Unfrozen ground.

The results provide more detailed information on the permafrost distribution and basic data for use in future research on the Tibetan Plateau permafrost.
