Abstract. 7Be and 210Pb air concentration and depositional flux data provide key information on the origins and movements of air masses, as well as 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 and particle dynamics and mixing processes in the 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 researchers and laboratories. Data were collected from published papers between 1955 and early 2020. It includes the annual surface air concentrations data of 7Be from 367 sites and of 210Pb from 270 sites, the annual depositional flux of 7Be from 279 sites, and of 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 available at https://doi.org/10.5281/zenodo.4521649 (Zhang et al., 2021). The purpose of this paper is to have the published data available in one place for future researchers' public consumption in their research and provide an overview of the scope and nature of this dataset holdings.

Short summary
Here we present a global dataset of air concentration and depositional flux measurements of atmospheric 7Be and 210Pb. The dataset could be used to better understand the transport processes of air masses and depositional processes of aerosols. This dataset not only lays a solid foundation to develop better parameterization contributing to future modeling efforts but also supply a basic parameter for tracing soil erosion, particle dynamics, and ocean surface process using 7Be and/or 210Pb.
