Weedon, Ellen Dorrepaal Bolin Centre Database 2020 Datafile Terrestrial Ecosystems Soil Rhizosphere priming Priming effect Permafrost PrimeSCale model Root distribution Northern circumpolar permafrost area Earth science > Cryosphere > Frozen ground > Permafrost Birgit Wild 2020-07-20T15:01:54+00:00 English 1 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 ###### Model code Matlab code for the PrimeSCale model is available at https://git.bolin.su.se/bolin/keuper-wild-2020. ###### Referencing Please cite both the dataset itself and the article by Keuper and Wild et al.
