The Regional Estimates of Vegetation Abundance from Large Sites (REVEALS) model was developed by Sugita (2007) to correct for bias due to inter-taxonomic differences in pollen productivity and dispersion and estimate plant cover at a regional spatial scale based on pollen records. We provide the dataset of pollen-based REVEALS reconstruction for temperate and northern sub-tropical China over the Holocene. The REVEALS reconstruction was achieved using 94 selected pollen records from lakes and bogs at a 1˚x1˚ spatial scale and a temporal resolution of 500 years between 11.7 and 0.7 ka BP, and three recent time windows (0.7˗0.35 ka BP, 0.35˗0.1 ka BP, and 0.1 ka BP˗present).

The dataset of pollen-based REVEALS reconstruction of Holocene plant cover for the study region includes the REVEALS proportions of plant cover (and related SEs) for 75 1˚x 1˚grid cells and 25 time windows for each grid cell for 27 taxa, two alternatives of aggregation of plant taxa to PFTs: ten PFTs and six PFTs, and three land-cover types. The metadata files providing details on the sites used in the REVEALS reconstruction for each grid cell and each time window. For instance, the original site names, modern vegetation zones, geographical coordinates (latitude and longitude in decimal degrees), elevation in meters above sea level, site types (bog or lake), basin sizes (radius and area), number of 14C radiocarbon dates or other types of dates, approximate temporal extent of the site. The dataset is suitable for palaeoclimate modeling, can be applied also in evaluating simulations of past vegetation from dynamic vegetation models and anthropogenic land cover change (ALCC) scenarios.

File naming and required software

The dataset of pollen-based REVEALS estimates of Holocene plant cover for temperate and northern sub-tropical China comprises four csv files with the REVEALS proportions of plant cover (and related SEs) for 75 1˚x 1˚grid cells and 25 time windows for each grid cell for 27 taxa (Data1.plants.csv), 2) six PFTs (Data2.6PFTs.csv), 3) three land-cover types (Data3.LCTs.csv) and 4）ten PFTs (Data4.10PFTs.csv). The grid_cell column in the data table is represented as coordinates of left bottom corner, time_window column shows the interval between the starting and end time of the data compiled for reconstruction, e.g. 100-350 represent 350-100 BP (before present). Four additional files are complementing various information for the REVEALS dataset. Such as the metadata (Table S1, pollen data for details), the details on the sites used in the REVEALS reconstruction for each grid cell and each time window (Table S2), three Land-cover types (LCTs) and six plant functional types (PFTs) and their corresponding pollen morphological types (Table S3), and finally ten plant functional types (PFTs) and their corresponding pollen morphological types Table S4.
Scientific paper of the 10 PFTs has been published in Li et al. (2020). Paper for the rest of the data will soon be published.
