Project: GCOS Earth Heat Inventory - A study under the Global Climate Observing System (GCOS) concerted international effort to update the Earth heat inventory (EHI), and presents an updated international assessment of ocean warming estimates, and new and updated estimates of heat gain in the atmosphere, cryosphere and land over the period from 1960 to present. Summary: The file “GCOS_EHI_1960-2020_Permafrost_Heat_Content_data.nc” presents the first estimate of permafrost heat storage within the Arctic region for the period 1960-2020. A perturbed parameter ensemble of simulations using the CryoGridLite permafrost model and climate forcings from the ERA-Interim reanalysis (1979-2020) and the Mk3L climate system model (500 CE -1979) allow to estimate the latent heat flux due to phase change in the subsurface from the surface to 550 m of depth. This ensemble of simulations allows to retrieve the uncertainty due to the unknown distribution of ground ice in the Arctic.
