[{"name":"hugelius-2020-peatland-1","title":"Maps of northern peatland extent, depth, carbon storage and nitrogen storage","summary":"This dataset contains GIS grids of peatland properties for the full northern hemisphere, north of 23\u00b0 N. The files include peatland extent, permafrost extent, peat depth, peat carbon storage, peat nitrogen storage and approximate extent of ombrotrophic\/minerotrophic peatlands.\r\n\r\nNorthern peatlands are important components in the Earth system and interact with both biogeochemical and hydrological cycles. These grids can be used for broad-scale analyzes of peatland properties and processes or to support development and validation of peatlands in models.  \r\n\r\nThe maps are based on a combination of reformatted northern hemisphere soil maps and spatial modelling. The maps of peatland extent (including different peatland types) are based on combinations of different harmonized local and regional maps. The peat depth maps were generated using random forest modelling from >7000 peat cores combined with environmental support data. The storage of carbon and nitrogen in peatlands was estimated from peat depth. ","citations":"Gustaf Hugelius, Julie Loisel, Sarah Chadburn, Robert B.
