Abstract. 7Be and 210Pb air concentration and depositional flux
data provide key information on the origins and movements of air masses, as
well as atmospheric deposition processes and residence time of aerosols.
After their deposition onto the Earth's surface, they are utilized for
tracing soil redistribution processes on land, particle dynamics in aquatic
systems, and mixing processes in open ocean. Here we present a global dataset
of air concentration and depositional flux measurements of atmospheric
7Be and 210Pb made by a large number of global research
communities. Data were collected from published papers between 1955 and
early 2020. It includes the annual surface air concentration data of
7Be from 367 sites and 210Pb from 270 sites, the annual
depositional flux data of 7Be from 279 sites and 210Pb from
602 sites. When available, appropriate metadata have also been summarized,
including geographic location, sampling date, methodology, annual
precipitation, and references. The dataset is archived at
https://doi.org/10.5281/zenodo.4785136 (Zhang et al., 2021) and is freely
available for the scientific community. The purpose of this paper is to
provide an overview of the scope and nature of this dataset and its
potential utility as baseline data for future research.
