ESA Permafrost Climate Change Initiative (Permafrost_cci): Permafrost active layer thickness for the Northern Hemisphere, v4.0
This dataset contains v4.0 permafrost active layer thickness data produced as part of the European Space Agency's (ESA) Climate Change Initiative (CCI) Permafrost project. It forms part of the third version of their Climate Research Data Package (CRDP v3). It is derived from a thermal model driven and constrained by satellite data. CRDPv3 covers the years from 1997 to 2021. Grid products of CDRP v3 are released in annual files, covering the start to the end of the Julian year. The maximum depth of seasonal thaw is provided, which corresponds to the active layer thickness.
Case A: It covers the Northern Hemisphere (north of 30°) for the period 2003-2021 based on MODIS
Land Surface temperature merged with downscaled ERA5 reanalysis near-surface air temperature data.
Case B: It covers the Northern Hemisphere (north of 30°) for the period 1997-2002 based on downscaled
ERA5 reanalysis near-surface air temperature data which are bias-corrected with the Case A product for
the overlap period 2003-2021 using a pixel-specific statistics for each day of the year.
