Permafrost degradation in the Western Russian Arctic
Abstract The Global Climate Observing System and Global Terrestrial Observing Network have identified permafrost as an ‘Essential Climate Variable,’ for which ground temperature and active layer dynamics are key variables. This work presents long-term climate, and permafrost monitoring data at seven...
