Siewert, Claire Treat, Merritt Turetsky, Carolina Voigt, Zicheng Yu Bolin Centre Database 2021 Datafile Terrestrial Peat Northern peatlands Peatland depth Peatland extent Peatland carbon Peatland nitrogen Earth science Gustaf Hugelius 2021-09-23T14:12:28+00:00 English 2 The dataset contains GIS-files in the Geotiff format as well as NetCDF files. The Geotiffs (file bundle with tif, cpg, dbf, xml and tfw-files) store integer data and are available in 10 km pixel resolution projected in the World Azimuthal Equidistant projection or in 0.1 degree resolution in WGS84 (lat/long). The NetCDF files are 0.1 degree resolution in WGS84 (lat/long). The definitions of peatland types and classes follows the US Soil Taxonomy. For further description 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 coverage of Histel peatlands that is expected to be minerotrophic in a given region. Note that this data is highly generalized and is not suitable for analyses at finer scales. * **Histel_ombrotrophic**: This file shows coverage of Histel peatlands that is expected to be ombrotrophic in a given region. Note that this data is highly generalized and is not suitable for analyses at finer scales. * **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 coverage of Histosol peatlands that is expected to be minerotrophic in a given region. Note that this data is highly generalized and is not suitable for analyses at finer scales. * **Histosol_ombrotrophic**: This file shows coverage of Histosol peatlands that is expected to be ombrotrophic in a given region. Note that this data is highly generalized and is not suitable for analyses at finer scales. * **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 (unit is cm) (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. #### Version history ##### Version 2 Files updated to fill data-gaps and data released in different formats (unprojected lat/long and as NetCDF). ##### Version 1 Initial release.
