Mean and variability of topsoil organic carbon concentrations across Great Britain derived at 1 km resolution from an ensemble of eight digital soil maps

This dataset presents the mean topsoil organic carbon concentration (g kg-1) and measures of its variability (standard deviation, coefficient of variation and signal to noise ratio) at 1 km2 resolution across Great Britain. The mean and variability metrics were calculated from an ensemble of eight previously published digital soil maps applied to all 1km grid cells across GB where data were available from all eight maps. Four of the maps were generated from the UKCEH Countryside Survey, two of which, CSGB-AIC and CSGB-GAMM are freely available online to use. Two maps are from International Soil Reference and Information Centre, ISRIC: SoilGrids250m v.1 (2017) and v.2 (2020) which are free to download. Two maps are from the Joint Research Centre (JRC): the OCTOP map of 2004 and LUCAS map of 2014 which are both free to download.

This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

THIS DATASET IS BEING QUALITY ASSURED. THE DATASET IS EXPECTED BECOME AVAILABLE (THROUGH THE EIDC) IN 2022.
