Abstract

A simple atmospheric impurity model is used to estimate changes in the atmospheric concentrations of soluble major ions, insoluble particulates and 10Be during the transition from glacial to Holocene conditions. The model interpolates between the flux and concentration records by explicitly allowing for wet- and dry-deposition processes. It is estimated that the atmosphere over Greenland sampled by snow accumulated during the younger Dryas cold event contained on average four-seven times the isoluble particulates and nearly seven times the soluble calcium derived from continental sources, and about three times the sea salt but only slightly more cosmogenic 10Be. -from Authors
