Earlier reported EMEP MSC-W modelled air concentrations and depositions

The depositions of sulphur (S) and nitrogen (N), and air concentrations of ozone (O 3) and particulate matter (PM) available here are calculated with the EMEP MSC-W model as earlier reported in the annual EMEP status reports.

Types of model calculations

As the EMEP MSC-W model calculations are changing with time, not only because of EMEP MSC-W model updates, but also due to modifications of the input data (e.g. revised emission data and meteorology). In broad terms, two types of model results can be distinguished:

Model results of Type1 are labeled by the year they are calculated for (e.g. '*2016met*' etc.), while model results of Type2 are further labeled by the year when the re-calculation was made. E.g. '*2013met_2013emis_rep2016*' refers to model results for the year 2013, which were obtained in 2016 using the best data available in 2016. Model results of Type2 should be preferred when doing trend analyses.

Emissions

The emissions used for the yearly model calculations have been derived from each years official data submissions to CEIP emission database/UNECE CLRTAP and are documented in the appendix of the respective EMEP Status Reports listed below.
