Comparison of measurement and modeling results of the global 10Be flux in topsoil

Abstract

Soils are among the major terrestrial reservoirs of atmospheric 10Be isotope and provide information of landscape evolution history. Despite this importance, there is no overview of the global soil 10Be fluxes in topsoil that is linked with atmospheric flux models. A comparison between measured (in topsoil) and atmospherically modeled 10Be fluxes is presented here. The data show relatively good agreement in the latitudinal trends. This feature demonstrates the potential to use the modeling data in estimating soil development/erosion rates in large scale basins where extensive 10Be measurements can be limited.
