| Summary: | <p>Relative pollen productivity (RPP) estimates are
fractionate values, often in relation to Poaceae, that allow vegetation
cover to be estimated from pollen counts with the help of models. RPP estimates are
especially used in the scientific community in Europe and China, with a few
studies in North America. Here we present a comprehensive compilation of
available northern hemispheric RPP studies and their results arising from 51
publications with 60 sites and 131 taxa. This compilation allows scientists
to identify data gaps in need of further RPP analyses but can also aid them
in finding an RPP set for their study region. We also present a
taxonomically harmonised, unified RPP dataset for the Northern Hemisphere
and subsets for North America (including Greenland), Europe (including
arctic Russia), and China, which we generated from the available studies. The
unified dataset gives the mean RPP for 55 harmonised taxa as well as fall
speeds, which are necessary to reconstruct vegetation cover from pollen
counts and RPP values. Data are openly available at
