Short summary
The deposition and preservation of NO3 across East Antarctica was investigated. On the coast, dry deposition contributes 27–44 % of the NO3 fluxes, and the linear relationship between NO3 and snow accumulation rate suggests a homogeneity of atmospheric NO3 levels. In inland snow, a relatively weak correlation between NO3 and snow accumulation was found, indicating that NO3 is mainly dominated by post-depositional processes. The coexisting ions are generally less influential on snow NO3.
