Taxonomically harmonized pollen percentages of European samples with revised chronologies

This data set consists of the taxonomically harmonized and temporally standardized fossil pollen data from 3680 records. 1122 records are located in North America, 1446 records in Europe, 687 records in Asia, 185 records in South America, 159 in Africa and 81 in the Indo-Pacific region. We expanded the previous version of the LegacyPollen 1.0 data set (Herzschuh et al., 2022; https://doi.org/10.5194/essd-14-3213-2022) with records from the Neotoma Paleoecology Database (https://www.neotomadb.org/; last access: August 31, 2022), ACER 1.0 database (Sánchez Goñi et al., 2017; https://doi.org/10.1594/PANGAEA.870867), Chinese fossil pollen dataset (Zhou et al., 2023, https://www.plant-ecology.com/CN/Y2023/V47/I10/1453 [in Chinese]; Cao et al., 2022, https://doi.org/10.1111/gcb.16274), and our own collection for the Asian sector. Taxonomic harmonization (i.e., woody taxa and major herbaceous taxa have been harmonized to genus level and other herbaceous taxa to family level) and temporal standardization (i.e., re-estimation of age-depth models) follow the previously established frameworks LegacyPollen 1.0 (Herzschuh et al., 2022; https://doi.org/10.5194/essd-14-3213-2022) and LegacyAge 1.0 (Li et al., 2022; https://doi.org/10.5194/essd-14-1331-2022), respectively. In compiling the dataset, we also followed the practices recommended by Flantua et al. (2023; https://doi.org/10.1111/geb.13693) for large-scale paleoecological data synthesis, such as how to select data sources and filter the dataset.

本数据集包含来自3680条记录的分类学统一且时间标准化的化石花粉数据。其中1122条记录位于北美洲，1446条位于欧洲，687条位于亚洲，185条位于南美洲，159条位于非洲，81条位于Indo-Pacific地区。我们在LegacyPollen 1.0数据集（Herzschuh等，2022；https://doi.org/10.5194/essd-14-3213-2022）的先前版本基础上进行了扩展，新增了来自Neotoma古生态数据库（https://www.neotomadb.org/；最后访问日期：2022年8月31日）、ACER 1.0数据库（Sánchez Goñi等，2017；https://doi.org/10.1594/PANGAEA.870867）、中文化石花粉数据集（Zhou等，2023，https://www.plant-ecology.com/CN/Y2023/V47/I10/1453 [中文]；Cao等，2022；https://doi.org/10.1111/gcb.16274）以及我们自己收集的亚洲区域数据记录。分类学统一（taxonomic harmonization，即木本类群和主要草本类群统一至属级，其他草本类群统一至科级）与时间标准化（temporal standardization，即重新估算年龄-深度模型（age-depth models））分别遵循先前建立的LegacyPollen 1.0（Herzschuh等，2022；https://doi.org/10.5194/essd-14-3213-2022）和LegacyAge 1.0（Li等，2022；https://doi.org/10.5194/essd-14-1331-2022）框架。在编译本数据集时，我们还遵循了Flantua等（2023；https://doi.org/10.1111/geb.13693）推荐的大规模古生态数据合成（large-scale paleoecological data synthesis）实践，例如如何选择数据源及过滤数据集。
