<abstract>
<p>The study reviews the emission estimates of sulphur oxides
      (SO&lt;sub&gt;x&lt;/sub&gt;) and primary particulate matter (PM) from the major
      industrial sources of Kola Peninsula. Analysis of the
      disagreements between the existing emission inventories for
      the Kola region combined with forward and inverse ensemble
      dispersion modelling, analysis of observation time-series and
      model-measurement comparison showed that the emission of the
      Nikel non-ferrous metallurgy plant was missing from the EMEP
      inventory, as well as from some others, being in some cases
      misplaced or mis-attributed to other sources of the
      region. A more consistent inventory of the anthropogenic
      emissions of SO&lt;sub&gt;x&lt;/sub&gt; and PM has been compiled for the peninsula,
      compared with the existing estimates and verified by means of
      dispersion modelling. In particular, the SILAM model
      simulations for 2003 and 2006 with the revised emission data
      showed much lower bias – up to 6 times for the most-affected
      sites – for SO&lt;sub&gt;2&lt;/sub&gt; with regard to the measured
      concentrations of 8 Finnish and Norwegian observational
      stations in the region. Temporal correlation improved
      moderately (10–20%) but homogeneously over Lapland. The
      study demonstrates the value of a combined usage of forward
      and inverse ensemble modelling for source apportionment in
      case of limited observational data.</p>
