摘要：Pollen records from Siberia are mostly absent in global or NorthernHemisphere synthesis works. Here we present a taxonomically harmonized andtemporally standardized pollen dataset that was synthesized using 173palynological records from Siberia and adjacent areas (northeastern Asia,42–75∘ N, 50–180∘ E).Pollen data were taxonomically harmonized, i.e. the original 437 taxawere assigned to 106 combined pollen taxa. Age–depth models for all recordswere revised by applying a constant Bayesian age–depth modelling routine.The pollen dataset is available as count data and percentage data in a tableformat (taxa vs. samples), with age information for each sample. The datasethas relatively few sites covering the last glacial period between 40 and11.5 ka (calibrated thousands of years before 1950 CE)particularly from the central and western part of the study area. In theHolocene period, the dataset has many sites from most of the area, with the exception of thecentral part of Siberia. Of the 173 pollen records, 81 % of pollen countswere downloaded from open databases (GPD, EPD, PANGAEA) and 10 % werecontributions by the original data gatherers, while a few were digitizedfrom publications. Most of the pollen records originate from peatlands(48 %) and lake sediments (33 %). Most of the records (83 %) have ≥3 dates, allowing the establishment of reliable chronologies. The datasetcan be used for various purposes, including pollen data mapping (example mapsfor Larix at selected time slices are shown) as well as quantitative climate andvegetation reconstructions. The datasets for pollen counts and pollenpercentages are available at https://doi.org/10.1594/PANGAEA.898616(Cao et al., 2019a), also including the site information, data source,original publication, dating data, and the plant functional type for eachpollen taxa.
