The core of this dataset consists of three multi band GeoTIFF files with Rhizosphere priming effect (RPE) ratios across the terrestrial northern circumpolar permafrost area, and three similar files with associated uncertainty estimates. The study area includes 33.7 million active grid cubes (561,956 grid cells), with a dimension of 5 km × 5 km × 5 cm. File size (all files together): 51 MB In addition, the dataset includes a spreadsheet file (xlsx), which contains intermediate output data of the PrimeSCale model in an easily accessible format. The dataset also includes a pdf with metadata for the model output data, which is the same as presented here: Model output data RPEs are summed over soil layers for each grid cell, in files with the following names: RPE_ratio.tif RPE_induced_SOC_loss_no_CN.tif RPE_induced_SOC_loss_with_CN.tif Associated uncertainty estimates are provided in: CV_RPE_ratio.tif CV_RPE_induced_SOC_loss_no_CN.tif CV_RPE_induced_SOC_loss_with_CN.tif Spatial metadata All model output files have the following spatial information: class: GeoTIFF dimensions: 1823, 1916, 3492868, 3 (nrow, ncol, ncell, nlayers) resolution: 5000 m, 5000 m (x, y) extent: -4752178, 4827822, -5148690, 3966310 (xmin, xmax, ymin, ymax) projection: NSIDC EASE-Grid North (EPSG:3408) crs: +proj=laea +lat_0=90 +lon_0=0 +x_0=0 +y_0=0 +a=6371228 +b=6371228 +units=m +no_defs 3rd layer: 1: present 2: RCP4.5 for 2100 3: RCP8.5 for 2100 Explanation of file names and file content RPE_ratio unit: - Rhizosphere priming ratio RPE_induced_SOC_loss_no_CN unit: 10⁶ g C km⁻² yr⁻¹ Rhizosphere priming induced soil organic carbon (SOC) loss over a year, without C/N threshold RPE_induced_SOC_loss_with_CN unit: 10⁶ g C km⁻² yr⁻¹ Rhizosphere priming induced soil organic carbon (SOC) loss over a year, with C/N threshold CV_* coefficient of variation (CV) for each above listed output parameter
