“…2 shows the monthly 7 Be and 210 Pb activity concentrations and precipitation in the study period. As shown in the figure, the activity concentrations of both 7 Be and 210 Pb showed seasonal variation; they were high in winter and low in summer, similar to those reported in Kumamoto, Japan (Momoshima et al, 2006), and Qingdao, China (Yang et al, 2013). Shenzhen is located in subtropical monsoon regions, which is wet and hot in summer and dry and cool in winter.…”

“…Shenzhen is located in subtropical monsoon regions, which is wet and hot in summer and dry and cool in winter. During the rainy season, precipitation scavenging causes the aerosol concentration to decrease, thus reducing the attachment medium for 7 Be and 210 Pb in the air (Yang et al, 2013). On the other hand, maritime air masses that come from the Pacific Ocean usually contain less 7 Be and 210 Pb, which may also be responsible for the low 7 Be and 210 Pb in summer.…”

Naturally occurring beryllium-7 ( 7 Be) and lead-210 ( 210 Pb) serve as powerful tracers in atmospheric studies. In this study, 7 Be and 210 Pb were simultaneously measured in atmospheric aerosols and deposition samples for an entire year (from January to December 2017) in Shenzhen, South China. The activity concentrations of the airborne 7 Be and 210 Pb ranged from 0.33 to 9.42 mBq m -3 (averaging 3.23 mBq m -3 ) and from 0.59 to 4.72 mBq m -3 (averaging 1.58 mBq m -3 ), respectively, and were observed to be high during the winter but low during the summer. Moreover, the relatively high 210 Pb concentration was probably due to the elevated level of radon in this region's soil. The deposition fluxes of the 7 Be and 210 Pb were found to range from 0.25 to 3.04 Bq m -2 day -1 (averaging 1.57 Bq m -2 day -1 ) and from 0.34 to 1.31 Bq m -2 day -1 (averaging 0.73 Bq m -2 day -1 ), respectively. The temporal trends of these fluxes were largely influenced by rainfall and the origin and pathway of air masses, as well as by atmospheric circulation. Based on their concentrations in the aerosols and their deposition fluxes, the average deposition velocities of 7 Be and 210 Pb were calculated to be 0.83 and 0.62 cm s -1 , respectively. The deposition velocities of both radionuclides correlated well with the amount of rainfall, indicating that precipitation plays a crucial role in removing 7 Be and 210 Pb from the air. The activity size distributions of these nuclides combined with the characteristic meteorological conditions in this region resulted in high deposition velocities during summer and low ones during winter.

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.
