[{"name":"palmtag-2022-spatial-1","title":"A high spatial resolution soil carbon and nitrogen dataset for the northern permafrost region","summary":"This spatial dataset is quantifying soil organic carbon (SOC) and total nitrogen (TN) storage with their carbon to nitrogen ratio (C\/N) in soils of the northern circumpolar permafrost region (17.9\u202f\u00d7\u202f10\u2076\u202fkm\u00b2) based on ESA\u2019s Climate Change Initiative (CCI) Global Land Cover dataset at 300 m pixel resolution.\r\n\r\nThe dataset contains GIS grids of the northern circumpolar permafrost region for SOC, TN and C\/N ratio for the following depth increments (0\u2060\u200a\u2013\u200a\u206030, 0\u2060\u200a\u2013\u200a\u206050, 0\u2060\u200a\u2013\u200a\u2060100, 100\u2060\u200a\u2013\u200a\u2060200, 200\u2060\u200a\u2013\u200a\u2060300, 0\u2060\u200a\u2013\u200a\u2060300 cm). These GIS grids are based on 651 soil pedons encompassing more than 6500 samples from 16 different study areas across the northern permafrost region.\r\n\r\nAdditional metadata with the actual pedon and profile data is available as a companion dataset.\r\n\r\n","citations":"Obu J, Westermann S, Bartsch A, et al.

The main aim of the field studies compiled in the companion dataset was to perform SOC\/TN pool inventories of each study area considering different land cover types, geomorphological landforms and soil properties.\r\n\r\nFor the upscaling, we used the land cover map from the Global ESA Land cover Climate Change Initiative (CCI) project at 300 m spatial resolution, retrieved from the [ESA Climate Change Initiative Land Cover](http:\/\/maps.elie.ucl.ac.be\/CCI\/viewer\/index.php) visualization interface.\r\n\r\nWe thank the ESA CCI Land Cover project for providing their data, which was used for upscaling our product to circumpolar scale.","category":"Terrestrial","subcategory":"Soil","keywords":"Soil organic carbon; Total nitrogen; Carbon to nitrogen ratio; Northern circumpolar permafrost region","scientist":"Juri Palmtag, Jaroslav Obu, Peter Kuhry, Matthias Siewert, Niels Weiss, Gustaf Hugelius","firstname":"Juri","lastname":"Palmtag","address":"Department of Human Geography; Stockholm University","postalcode":"SE-106 91","city":"Stockholm","province":"","country":"Sweden","parameters":"Earth science > Land surface > Soils > Carbon","location":"Geographic Region > Northern Hemisphere","progress":"Completed","language":"English","project":"This study was funded through the European Space Agency CCI + Permafrost project (4000123681\/18\/I-NB), the European Union Horizon 2020 research and innovation project Nunataryuk (773421) and the Swedish Research Council (2018-04516).","publisher":"Bolin Centre Database","version":"1","constrains":"","access":""}]
