A comprehensive global dataset of atmospheric 7Be and 210Pb measurements: air concentration and depositional flux
收藏资源简介：
Naturally occurring beryllium-7 (<sup>7</sup>Be, T<sub>1/2</sub>: 53.3 days) and lead-210 (<sup>210</sup>Pb, T<sub>1/2</sub>:22.3 y) have been widely utilized as tracers to investigate Earth’s surface processes. Here we present a global dataset of air concentration and depositional flux measurements of atmospheric <sup>7</sup>Be and <sup>210</sup>Pb 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 <sup>7</sup>Be from 367 sites and of <sup>210</sup>Pb from 270 sites, the annual depositional flux of <sup>7</sup>Be from 279 sites, and of <sup>210</sup>Pb from 602 sites. When available, appropriate metadata have also been summarized, including geographic location, sampling date, methodology, annual precipitation, and references.
