We developed and tested a regression model, interpolating long-term sequences of observed atmospheric deposition of sulphate, nitrate, and ammonium in the upper Vltava river catchment (Czech Republic). Ion fluxes are calculated as the product of the precipitation and ion concentrations, which both are derived as empirical functions of elevation and time. The long-term sequences of ion concentrations are based on measured deposition data at 19 stations and their relationships with central European emission trends of S and N. Exponential relationships between elevation and precipitation volume (positive) and elevation and ion concentrations (negative) are used to convert the long-term sequences of precipitation and concentrations into values for individual elevations. Throughfall fluxes (TF) of S and N in the forest areas are calculated from their fluxes in precipitation (PF), using long-term sequences of TF:PF ratios, based on measured fluxes and the S and N emission trends.
