The data provided have been prepared for use by the Land Resource Management Unit (Institute for Environment and Sustainability) of the Joint Research Centre (JRC) of the European Commission. This metadata refers to two maps: a) Map of predicted topsoil organic carbon content (g C kg-1) : The map was produced by fitting a generalised additive model between organic carbon measurements from the LUCAS survey (dependent variable) and a set of selected environmental covariates; namely slope, land cover, annual accumulated temperature, net primary productivity, latitude and longitude. The format provided is GeoTIFF. b) Map of standard error of the OC model predictions (g C kg-1): This map presents the associated uncertainty to the organic carbon content predictions. The standard error, which shows the theoretical range of deviation in the prediction made by the generalized additive model, was calculated for every pixel of the Map of predicted topsoil organic carbon content, based on the posterior covariance matrix of the fitted parameters. The format provided is GeoTIFF. The map of predicted OC content had the smallest values in Mediterranean countries and in croplands across Europe, whereas largest OC contents were predicted in wetlands, woodlands and mountainous areas. The map of the predictions' standard error had large uncertainty in northern latitudes, wetlands, moors and heathlands, whereas small uncertainty was mostly found in croplands. The map produced gives the most updated general picture of topsoil OC content at the European Union scale.EU25SoilCarbonLand coverModelOrganic carbonSlopeEuropeanEU25Soil <http://www.opengis.net/def/crs/OGC/1.3/CRS84> Polygon((-31.28 27.64, -31.28 70.08, 34.10 70.08, 34.10 27.64, -31.28 27.64)) Direct download (Eionet authentication)https://sdi.eea.europa.eu/data/75033661-550e-4c36-b1b7-b502ec545aa7Join Research Centre European Soil Data Centre (ESDAC)https://esdac.jrc.ec.europa.eu/content/topsoil-soil-organic-carbon-lucas-eu25EEA Geospatial Data Cataloguehttps://sdi.eea.europa.eu/catalogue/srv/eng/catalog.search#/metadata/75033661-550e-4c36-b1b7-b502ec545aa7Joint Research Centre (JRC), European CommissionEnglish
