Ground temperature and frozen-soil maps, High Mountain Asia (1 km)

High Mountain Asia 1 km MODIS-AIRS Gap-Filled Ground Temperatures and Permafrost Probability Maps, 2003-2016 V001
land NASA NSIDC_CPRD Level 4 netCDF-4
In plain English

What it measures. Monthly ground and land-surface temperature maps for the High Mountain Asia region, plus estimates of how likely permafrost (permanently frozen ground) is in each spot, at about 1-kilometer detail from 2003 to 2016.

How it's made. Created by filling gaps in MODIS satellite surface-temperature readings using temperature data from the AIRS instrument, so the maps are complete even where clouds blocked the view.

How & where you'd use it. Helps scientists track frozen ground and ground temperatures across this remote mountain region, which matters for water supply, landslides, and climate change.

Official description

This data set consists of 1 km resolution monthly land surface temperatures (MLSTs); mean annual ground temperatures (MAGTs); and estimates of permafrost extent (PE) in the High Mountain Asia region from 1 Jan 2003 – 31 Dec 2016. The data were generated by gap-filling daily MODIS Terra/Aqua Land surface temperatures (LSTs) with downscaled Atmospheric Infra-Red Sounder (AIRS) skin surface temperatures.
