Mapping deposition of sulphur, nitrogen and base cations in the Nordic countries

Technical Report:

Abstract

The main purpose of this joint Nordic effort was to map total deposition using available data from measurements of precipitation, ambient air quality and throughfall. Data from national networks were combined in order to avoid discontinuities along the national borders. The deposition of sulphur, nitrogen and base cations were estimated using monitoring results on wet deposition, throughfall, air pollution concentrations and literature data on nitrogen deposition velocities. Wet deposition data formed the basis of the mapping procedure. In addition to the wet deposition, dry deposition is calculated from air pollution concentrations and deposition velocities (for nitrogen) or deposition factors derived from throughfall measurements (for sulphur). The dry deposition of base cations were estimated as a factor derived from the throughfall to wet deposition ratio for sodium. The throughfall results used for deriving deposition factors are the Scandinavian results for sulphur. The deposition to forest ecosystems was produced in order to compare it to critical loads for forest soils and to make exceedance maps for the sensitive forest ecosystems. The results were also compared with results from atmospheric dispersion and deposition models, using the integrated deposition over all types of areas within the Environmental Monitoring and Evaluation Programme (EMEP) grid squares.  More>>
