Numerous long-term measuring stations for monitoring permafrost conditions, micrometeorology, the [...] largest nature reserves. This unique region is crucial for understanding the processes that influence permafrost in the Siberian Arctic.

(Photo: Julia Boike) Observational data density in the permafrost region is low. At the Samoylov site in the Lena River Delta, Siberia, the mean permafrost temperature was −8 °C, with a zero-amplitude depth [...] layer, temperature down to 26 m in the permafrost. Since the data provide observations of temporally variable parameters that mitigate energy fluxes between permafrost and atmosphere, they are suitable for [...] for use in integrating, calibrating and testing permafrost as a component in earth system models.

The thawing of permafrost poses various endangerments to the Arctic environment and the livelihoods of people. An international team examined the social risks for Arctic regions and identified five key risks related to infrastructure, transport and supply, water quality, food security and health.
