Compilation of pollen productivity estimates and taxonomically harmonised relative pollen productivity (RPP) datasets for Europe, northern America, China and the Northern Hemisphere extratropics

Relative pollen productivity (RPP) estimates allow to recalculate vegetation cover from pollen counts. This dataset contains:* a comprehensive compilation of available RPP studies and their data including information on the study design and models used to calculate the RPP values in the original studies.* taxonomically harmonised RPP datasets for America (including Greenland), Europe (including Arctic Russia), China and one combined for the whole Northern hemisphere extratropics built out of the available studies.* fall speeds, which are necessary to reconstruct vegetation cover out of pollen counts and RPP values.We advise the user to read the manuscript doi:10.5194/essd-2019-242 accompanying the dataset prior to use especially the taxonomically harmonised datasets.
