Mapping of base cation deposition in the Nordic countries

Creator/Principal investigator(s):

Description:

Base cation deposition from the atmosphere provides, together with weathering, ions for neutralising acidity and, after sufficient reductions of acidifying deposition, a source for replenishing lost base cation pools. 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.
