Siewert, Claire Treat, Merritt Turetsky, Carolina Voigt, Zicheng Yu Maps of northern peatland extent, depth, carbon storage and nitrogen storage Bolin Centre Database 2020 Datafile Terrestrial Peat Northern peatlands Peatland depth Peatland extent Peatland carbon Peatland nitrogen Earth science Gustaf Hugelius 2020-07-28T07:32:44+00:00 English 1 The dataset contains GIS-files in the grid (raster) format. Each grid consists of a GeoTiff file bundle with tif, cpg, dbf, xml and tfw-files. The grids store integer data and are in 10 km pixel resolution projected in the World Azimuthal Equidistant projection. The definitions of peatland types and classes follows the US Soil Taxonomy, for further decsription of definitions and methods we refer to Hugelius et al. (2020). Below, a brief description of each file is included (in alphabetic order): * **Histel_fraction**: This file shows the estimated coverage in percent of permafrost peatlands (Histels) in each gridcell. * **Histel_minerotrophic**: This file shows the percent of Histel peatlands that is expected to be minerotrophic in a given region (together with Histel_ombrotrophic it should add up to 100%). Note that this data is highly generalized and is not suitable for analyses at finer scales. This file has coverage everywhere, including where there are no peatlands. This is because it is scaled, and extrapolated, based on generalized biome distribution maps. * **Histel_ombrotrophic**: This file shows the percent of Histel peatlands that is expected to be ombrotrophic in a given region (together with Histel_minerotrophic it should add up to 100%). Note that this data is highly generalized and is not suitable for analyses at finer scales. This file has coverage everywhere, including where there are no peatlands. This is because it is scaled, and extrapolated, based on generalized biome distribution maps. * **Histel_SOC_hg_per_sqm**: This file shows estimated storage of organic carbon in peat of Histel peatlands (unit is hg m⁻²). * **Histel_TN_gram_per_sqm**: This file shows estimated storage of total nitrogen in peat of Histel peatlands (unit is gram m⁻²). * **Histosol_fraction**: This file shows the estimated coverage in percent of non-permafrost peatlands (Histosols) in each gridcell. * **Histosol_minerotrophic**: This file shows the percent of Histosol peatlands that is expected to be minerotrophic in a given region (together with Histosol_ombrotrophic it should add up to 100%). Note that this data is highly generalized and is not suitable for analyses at finer scales. This file has coverage everywhere, including where there are no peatlands. This is because it is scaled, and extrapolated, based on generalized biome distribution maps. * **Histosol_ombrotrophic**: This file shows the percent of Histosol peatlands that is expected to be ombrotrophic in a given region (together with Histosol_minerotrophic it should add up to 100%). Note that this data is highly generalized and is not suitable for analyses at finer scales. This file has coverage everywhere, including where there are no peatlands. This is because it is scaled, and extrapolated, based on generalized biome distribution maps. * **Histosol_SOC_hg_per_sqm**: This file shows estimated storage of organic carbon in peat of Histosol peatlands (unit is hg m⁻²). * **Histosol_TN_gram_per_sqm**: This file shows estimated storage of total nitrogen in peat of Histosol peatlands (unit is gram m⁻²). * **Mean_potential_peat_depth_cm**: This file shows the estimated potential depth of peatlands in all locations (generated using peat cores and machine learning). This file was combined with the peatland extent maps to estimate storage (per square meter) and total stock of carbon and nitrogen in peatlands. The total size of all files is 9.2 MB.
