Abstract. Here we describe the LegacyPollen 1.0, a dataset of 2831 fossil pollen records with metadata, harmonized taxonomy, and standardized chronologies. A total of 1032 records originate from North America, 1075 from Europe, 488 from Asia, 150 from Latin America, 54 from Africa, and 32 from the Indo-Pacific. The pollen data cover the Late Quaternary (mostly the Holocene). The original 10,110 pollen taxa names (including variations in the notations) were harmonized to 1002 taxa, with woody taxa and major herbaceous taxa to genus level and other herbaceous taxa to family level. The dataset is valuable for synthesis studies such as taxa areal changes, vegetation dynamics, human impact (e.g., deforestation), and climate change at global or continental scales. The harmonized pollen and metadata as well as the harmonization table are available from PANGAEA (https://doi.pangaea.de/10.1594/PANGAEA.929773; Herzschuh et al., 2021a). R code for the harmonization is provided at Zenodo (https://doi.org/10.5281/zenodo.5910972; Herzschuh et al., 2022) so that datasets at a customized harmonization level can be easily established.

Short summary
Pollen preserved in environmental archives like lake sediments and bogs are broadly used for the reconstructions of past vegetation and climate. Here we present LegacyPollen 1.0, a dataset of 2831 fossil pollen records from all over the globe that were collected from publicly available databases. We harmonized the names of the pollen taxa so that all datasets can be jointly investigated. LegacyPollen 1.0 is available as an open-access dataset.
