Data sets

Snow chemical compositions, salinity, surface ozone, BrO and meteorology data at Eureka, Canada in spring of 2018/19 (Version 1.0) Xin Yang and Kimberly Strong

Short summary
This study uses snow samples collected from a Canadian high Arctic site, Eureka, to demonstrate that surface snow in early spring is a net sink of atmospheric bromine and nitrogen. Surface snow bromide and nitrate are significantly correlated, indicating the oxidation of reactive nitrogen is accelerated by reactive bromine. In addition, we show evidence that snow photochemical release of reactive bromine is very weak, and its emission flux is much smaller than the deposition flux of bromide.
