EMEP/MSC-W calculated SR Tables

This site contains downloable Excel tables with country-to-country source-receptor matrices for depositions of sulphur and nitrogen, and concentrations of ozone (O3) and particulate matter (PM). Calculations for the different years are based on different versions of the EMEP MSC-W model, emissions and meteorological drivers, except for the recalculations (rep2009). Thus, tables for all compounds are not available for all years (some O3 and PM compounds). Calculations for the years since 2007 and recalculations of previous years (rep2009) are covering the extended EMEP grid. Other EMEP MSC-W Model results can be found under Downloadable data from left menu on EMEP MSC-W page .

The source-receptor (SR) relationships give the change in air concentrations or depositions resulting from a change in emissions from each emitter country. For each country, reductions in six different pollutants have been calculated separately: with an emission reduction of 15% for SOx, NOx, NH3, NMVOC, PPM2.5 or PPMcoarse respectively. The deposition tables show the contribution from one country to another. They have been calculated adding the differences obtained by a 15% reduction for all emissions in one country multiplied by a factor of 100/15, in order to arrive at total estimates. For the concentrations and indicator tables, the differences obtained by the 15% emission reduction of the relevant pollutants are given directly. Thus, the tables should be interpreted as estimates of this reduction scenario from the chemical conditions of the given year.

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:

In 2009, SR trend matrices were produced for the years 1997-2006 (Type 2). Else there are available reported SR tables since 2003 (Type 1). All modelled compounds (listed below) with the different emission reductions for all emitting regions and their identifying codes can be retrieved in one single Excel file (until 2010) or tar file of CSV files (+ README file) (since 2011) for each year:

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 EMEP Status Reports listed below.
