Mapping of base cation deposition in the Nordic countries

The present dataset is a mapping of base cations over the Nordic countries and was performed using the data assimilation part of the SMHI MATCH-model as of 2003 (optimum interpolation) with a grid spacing of 11km.

The mapping was based on monitoring data for concentrations of base cations in air and precipitation in the Nordic and surrounding countries. For a detailed description of the methodology the reader is refered to Lövblad et al., 2003, pp7-14.
