This set of files store model simulations using the biosphere model Dynamic Vegetation Model Dynamic Organic Soil Terrestrial Ecosystem Model (DVM-DOS-TEM), developed to represent the effect of deep nitrogen acquisition by the vegetation on the permafrost carbon feedback. Simulations were conducted at a 1km resolution, over a 2,500 km2 area (50x50km square) centered on two long term ecological research sites in Alaska: Eight Mile Lake located in Interior Alaska (63.8900° N, 149.2535° W), and Toolik Field Station located on the northern foothills of the Brooks range (68.6500° N, 149.5800° W). Historical simulations are spanning the 1950 to 2015, and forced using climate simulations from the Climate Research Unit, time series 4.0. Future simulations are spanning 2016 to 2100, and forced using atmospheric CO2 emission scenario Representative Concentration Pathway (RCP) 8.5 and climate simulations from the Coupled Model Intercomparison Project Phase 5 (CMIP5) for two global circulation models: the Meteorological Research Institute (MRI) and National Center for Atmospheric Research (NCAR). The variables that are produced are gross primary productivity (GPP, in gC.m-2.y-1), net primary productivity (NPP, in gC.m-2.y-1), Heterotrophic respiration (RH in gC/m2/y-1), and active layer depth (ALD, m). The data are stored in netcdf files, the projection of used is NAD83/Alaska alders conical equal area (EPSG 3888).
