Biological processes such as microbiological processes,organic matter decomposition, CO2 and CH4 and N2O fluxes are strongly controlled by the active layer temperature and moisture(the thin layer of soil above the permafrost that experiences annual freeze/thaw).MAMap –Methane Airborne mapperGlobal warming is most pronounced in high-latitudes.EO Earth ObservationRegional climate model COSMO-CLM (model of the Consortium for Small-scale Modellingin CLimate Mode)Konstanze Piel installing a permafrost depthprofile (moisture,    temperature) in Spitsbergen.Eddy covariance measurements (energy, water, CO2, CH4) at the long-term Samoylov measurement field, Siberia, Torsten Sachs.23.08.2010 Samoylov measurement field:“Prime Minister Vladimir Putin visits the sites explored by the Russian and German expedition Lena 2010 and speaks with the research team.
