Permafrost is a key element of the cryosphere and an essential climate variable in Global Climate Observing System. There no remote-sensing method available to reliably monitor permafrost thermal state. To estimate distribution at hemispheric scale, we employ equilibrium state model for temperature top (TTOP model) 2000–2016 period, driven by remotely-sensed land surface temperatures, down-scaled ERA-Interim reanalysis data, tundra wetness classes landcover map from ESA Landcover Change...
Monitoring of the thickness active layer within lake-marsh type terrain in northern taiga was carried out at three sites organized 1997, 2013 and 2022. In these areas, two types tracts are distinguished: frozen peat bogs swampy runoff hollows with a lowered roof permafrost (the cross-section is same type, only difference peat). The work methodology complied unified protocol international CALM program. Additionally, surface settlement assessed (based on leveling from local benchmark),...
