Description
This dataset provides annual estimates of active layer thickness (ALT) at 1 km resolution across Alaska from 2001-2015. The ALT was estimated using a remote sensing-based soil process model incorporating global satellite data from Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST) and snow cover extent (SCE), and Soil Moisture Active and Passive (SMAP) satellite soil moisture records. The study area covers the majority land area of Alaska except for areas of perennial ice/snow cover or open water. The ALT was defined as the maximum soil thawing depth throughout the year. The mean ALT and mean uncertainty from 2001 to 2015 are also provided.

Black dots are locations of circumpolar active layer monitoring (CALM) sites used for comparison of observed ALT to modeled ALT. CALM data are not provided. The areas with ALT greater than 300 cm depth are shown in dark gray. (Source: Yi et al. 2018) | Open resource |
