1 Norwegian Meteorological Institute met.no EMEP data on the web SR Tables National reports Michael Gauss

2 Norwegian Meteorological Institute met.no Outline What kinds of EMEP MSC-W model output can be found on emep.int? Focus on source-receptor matrices (SR tables) – Where to find the data? – How are these data calculated and how to interpret them? Focus on national reports (country notes) – Useful country-specific information from EMEP MSC-W for the parties of CLRTAP

6 Concentrations and depositions from the EMEP MSC-W model Type 1) Model results that have been officially reported, based on model simulations using the best available input data at the time of reporting Type 2) Model results from later re-calculations, using updated input data which were not available at the time of reporting

7 Norwegian Meteorological Institute met.no The data selection table

8 Norwegian Meteorological Institute met.no The SR tables Published in the appendices of the EMEP status reports every year

9 Norwegian Meteorological Institute met.no Fundamental questions of LRTAP 1.Where do the pollutants in a given country or region come from? 2.Where do the pollutants emitted by a country or region end up?

10 Norwegian Meteorological Institute met.no The source-receptor (SR) relationships give the change in air concentrations or depositions resulting from a change in emissions from an emitter country For each of the 50 countries, reductions in six different pollutants are calculated separately – 15% reduction in emissions of SOx, NOx, NH 3, NMVOC, PPM fine, or PPM coarse. EMEP MSC-W model runs

11 Norwegian Meteorological Institute met.no Deposition tables Total contribution from one country to another Calculated by adding the differences due to a 15% reduction in all emissions from one country, multiplied by a factor of 100%/15%

12 Norwegian Meteorological Institute met.no Concentration and indicator tables The effects of a 15% reduction in pollutant emissions are given directly They should be interpreted as a possible result of emission reduction measures

13 Norwegian Meteorological Institute met.no indigenous pollution An example from the EMEP status report

14 Norwegian Meteorological Institute met.no …a closer look at the bottom of this table

15 Norwegian Meteorological Institute met.no …and the far right

16 Norwegian Meteorological Institute met.no The Country notes

17 Norwegian Meteorological Institute met.no Example: The United Kingdom 2010 Spatial distribution of NMVOC emissions from the UK in Gg. Emission trends in the UK, various species (2012 data from CEIP); and emissions projected for 2020 (revised Gothenburg protocol). Gg.

18 Norwegian Meteorological Institute met.no Sulphur deposition from UK Contribution of emissions from the UK to deposition of oxidised sulphur in the EMEP domain. Unit: mg(S)/m 2. The six main receptor areas where oxidised sulphur from the UK is deposited. Unit: %.

19 Norwegian Meteorological Institute met.no Transboundary contribution Fraction of transboundary contribution to total sulphur deposition in the UK (%). Same for PPM 2.5

20 Norwegian Meteorological Institute met.no Example of an air quality indicator The six most important contributors to SOMO35 in the UK related to emissions of NOx (left) and NMVOC (right). Unit: %. 2009

21 Norwegian Meteorological Institute met.no Observations! Frequency analysis of ozone in the UK at the stations that reported ozone for 2010 (Model, Observations) ppbv

22 Norwegian Meteorological Institute met.no Conclusions emep.int has been there for a long time and has a lot to offer (young generation: please have a look and browse!) «Its so 2000» : The website is currently restructured to make it more appealing to new users (and even more functional to the old) Please note that this presentation was only about EMEP MSC-W model results – SR tables are among the key model output from EMEP – country notes are provided to all parties of the Convention (except North America)
