The CARDAMOM model-data fusion (MDF) software was used to generate an analysis (0.5x0.5 degree, 2001-2019, monthly time step) of the carbon (C) and water (H2O) cycles across the global terrestrial permafrost regions. CARDAMOM used time series information on leaf area index, total woody biomass, net biome exchange of CO2 and a prior in the initial value of soil C stocks, to train an intermediate complexity model of the terrestrial ecosystem (DALEC4). CARDAMOM retrieves ensembles of parameters are estimates for DALEC4 uniquely for each pixel within the analysis domain, from these ensembles the uncertainty associated with analysis can be directly quantified. Permafrost domain defined under the RECCAP2 definition (https://www.globalcarbonproject.org/reccap/, accessed 22/08/2023). The analysis output includes uncertainty bounded estimates of ecosystem gross fluxes (e.g. photosynthesis, plant respiration, decomposition and fire), C stocks (labile, foliage, wood, fine roots, litter and soil) and their internal ... : Metadata for the variables provided are given in the netcdf files. This includes the complete geographic extent and temporal coverage and variable definitions. ...
