The submitted dataset includes the pollen-based REVEALS estimates of 11 plant functional types (PFTs) and 3 land-cover types (LCTs) for Europe, published in Trondman et al. (2015) as part of the results from the Swedish project LandClim I (Gaillard et al., 2010). In this project, pollen-based REVEALS estimates of land cover for 5 time windows of the Holocene were used to evaluate the scenarios of anthropogenic land-cover change (ALCC) KK and HYDE (Kaplan et al., 2017) and to study the biogeophysical forcing of ALCC between the time windows 6200-5700 years BP and CE 1600-1850 (Strandberg et al., 2014). The reconstruction is based on 25 pollen taxa for which pollen productivity of the corresponding plant taxa were available. The taxa included in the 11 PFTs and 3 LCTs are shown in Table 1 of Trondman et al. (2015). The REVEALS estimates for the 25 individual taxa will be submitted later. See details on the REVEALS model (Sugita, 2007) under "The REVEALS model".The REVEALS data filesThe LandClim I pollen-based REVEALS reconstructions of land cover are gridded with a cell size of 1°. The file LandClim I LCTs.xls contains the REVEALS estimates of the cover of three land-cover types (LCTs), Evergreen Trees (ET), Summer-green Trees (ST) and Openland (OL). The file LandClim I PFTs.xls contains the REVEALS estimates of the cover of 11 plant functional types (PFTs) (see folder "Metadata" in the excel file for details). In both excel files, the folder "Metadata" contains the explanation of abbreviations in the data folders, the folder "Sitedata" is the Metadatafile of the pollen records used for the REVEALS reconstructions, and there are 10 REVEALS data/results folders of which the first five folders contain the REVEALS estimates for the five time windows of the LandClim I project, and the last five folders contain the corresponding standard errors (SEs) on the REVEALS estimates. All REVEALS estimates and their SEs are given in proportions of the grid cell (the total of all REVEALS estimates sum up to 1). In each data/results folder, the columns LCGRID and LCGRID_ID are project internal IDs, the column "cell" is the coordinate of the upper left (NW) corner of the grid, and the column "Cell label" is the country number of the grid cell with REVEALS data/results. In the file LandClim I LCTs.xls, the five folders "....BPmeanLC" contain the REVEALS estimates of the three land-cover types for the five time windows, and the five folders "....BPSE" contain the standard errors (SE) on the LCT REVEALS estimates. In the file LandClim I PFTs.xls, the five folders "....BPmeanLC" contain the REVEALS estimates of the 11 plant functional types for the five time windows, and the five folders "....BPSE" contain the standard errors (SE) on the PFT REVEALS estimates.
