Meteorological Synthesizing Centre - East (MSC-E)

  is one of the international research Centres of the EMEP programme operating under the LRTAP Convention of UNECE.

  The Centre focuses its efforts on model assessment of the environment pollution with various toxic substances. >>>

TF HTAP Workshops on Hg and POPs Trends and Source Attribution

Two scientific workshops on Hg and POPs were jointly organized by Meteorological Synthesizing Center-East (MSC-E) and the Task Force on Hemispheric Transport of Air Pollution (TF HTAP) in April 2021. The workshops were aimed at development of a program of future Hg and POP activities within TF HTAP. They were particularly focused on (i) anticipating assessment needs of the LRTAP, Minamata, and Stockholm Conventions; (ii) reviewing progress made in other forums, including recent AMAP assessments; (iii) identifying cooperative activities that can be undertaken in the short term (2 years) and longer term (4-5 years) to improve our understanding and ability to estimate Hg and POPs pollution levels, trends and source attribution.   Read more…



Cooperation with maritime conventions (OSPAR, HELCOM)

MSC-E continued cooperation with the OSPAR and HELCOM marine conventions. OSPAR is focused on protection of the marine environment of the North-East Atlantic. HELCOM was established to protect environment of the Baltic Sea area.  In 2021 evaluated atmospheric loads of heavy metals (Pb, Cd, Hg, Cu) and POPs (HCB, PBDE) long-term trends of atmospheric pollution and source attribution for the OSPAR regions of the North-East Atlantic and for the Baltic Sea and its sub-basins. It is important to note that long-range trends of atmospheric loads of the second priority metals (Cu) to the Baltic Sea was be assessed for the first time.


Case Study

The Meteorological Synthesizing Center-East (MSC-E) has been conducting a number of country-specific case studies for over 10 years with the support of the Task Force on Measurements and Modeling (TFMM). Objective of the study is to provide the counties with detailed information on pollution levels in addition to the regular information generated within EMEP. The countries receive detailed data on pollution levels with fine spatial resolution, source apportionment of pollution for provinces and cities, contribution of emission sectors and large point sources etc. In 2020, within the framework of the Case Study, a project to assessment the pollution of Germany was completed. The results of this work are presented in the Joint Report of MSC-E and German Environment Agency.

"Assessment of Heavy Metal Pollution Levels in the Czech Republic (EMEP case study)" 

Stations measuring Cd concentrations in air and in precipitation at the Czech national monitoring network. Green circles denote all stations, white circles - priority stations selected for the analysis, red squares - EMEP stations

The Czech Republic provided information on cadmium concentrations in air from 72 national monitoring stations, and concentrations in precipitation from 30 stations. Eight background regional stations with co-located measurements (i.e., measurements of concentrations both in air and in precipitation) were selected for the detailed analysis of pollution levels in the country. Two of them (Kosetice and Svratouch) report annually information on heavy metal concentrations and deposition to EMEP.

Modelling of cadmium concentrations and deposition was carried out for 2007 with spatial resolutions of 50x50 km and 5x5 km. Calculations with resolution 50x50 km were performed on the base of EMEP officially reported emission data. For simulations with resolution 5x5 km emission data for the Czech Republic were provided by national experts, while for other countries the EMEP emissions were re-gridded from 50-km to 5-km resolution.

Calculated fields of cadmium concentrations in air and total deposition generally reflected spatial distribution of the emissions. Patterns of pollution levels simulated with 5x5 km and 50x50 km resolution were similar. However, maps with finer resolution demonstrated much more detailed picture of country-scale pollution levels.

Refinement of spatial resolution of emission and meteorological data resulted to reduction of discrepancies between modelled and measured annual mean concentrations of Cd at the priority stations.

Time series of calculated concentrations modelled with different spatial resolution are compared with time series of concentrations observed at the Czech stations. Analysis of selected short-term pollution episodes allows to examine factors responsible for Cd levels in the atmosphere. Analysis of some of episodes is available in technical and status reposts. Further analysis will be continued.
