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. >>>

Main research activities in 2022

Eurodelta-Carb activities

Multi-model analysis of B(a)P pollution levels in Europe is being performed as a part of the joint TFMM/EuroDelta-Carb intercomparison exercise of national experts and MSC-E. Main objectives of the study on B(a)P are to explore the model performance, analyze sources of uncertainties of modelling results, and to contribute to the refinement of B(a)P emissions from the combustion of fossil fuel and biomass burning. Preliminary analysis of modelling results demonstrates generally reasonable level of agreement of model predictions with observed B(a)P concentrations. At the same time, for some of the stations modelled concentrations significantly deviated from the observed values indicating possible effect of uncertainties in emission estimates, modelling approaches, and measurements. It is planned to perform more detailed analysis to explore the reasons of the differences between the output of participating models, the deviations of the model predictions from observed B(a)P concentrations, and to compare other characteristics and parameters (e.g.  B(a)P concentrations in precipitation and deposition fluxes, concentrations of species affecting B(a)P chemical transformations in the atmosphere). 


PAH pollution: a case study for Poland

PAH pollution assessment on a national scale was continued in the framework of a country-scale study for Poland. The second phase of the study was focused on the model assessment of B(b)F, B(k)F, and I(cd)P. In particular, analysis and update of model parameterizations for these compounds was carried out. The GLEMOS model was used to evaluate previous and updated national emission inventories of these PAHs. Results of model simulations showed that updated national PAH emission inventory (reported to EMEP) allowed to achieve improvement of pollution assessment accuracy for B(b)F and B(k)F. At the same time, no improvements were seen in case of I(cd)P. On the whole, the study showed that the modelling results still tend to underpredict observed air concentrations of PAHs in the country. Thus, further activities to refine emission estimates and to reduce uncertainties of the model parameterizations for PAHs are of importance.

Mercury pollution: A case study for Norway

A detailed study of Hg pollution on a country scale was performed for Norway as a part of the Norwegian Mercury Assessment 2022 (NMA 2022). The study was carried out in close collaboration with national experts and involving detailed national data on observations and emissions. Elevated Hg deposition levels were found in the southern part of the country and along the coast including the most northern areas, whereas low levels occur in the inland territories of the country. Mercury deposition to the country underwent relatively small reduction over past 30 years because of significant contribution of global emissions, which have been slowly changing. The study could useful for the effectiveness evaluation of national and international pollution reduction measures.

Cooperation with OSPAR convention

MSC-E completed assessment of atmospheric loads of Pb, Cd and Hg to the marine regions of the North-East Atlantic under support of the OSPAR Commission. Long-term deposition trends for the period from 1990 to 2019 were calculated for each OSPAR maritime region and source-receptor relationships were estimated for 1995, 2005 and 2015. The modelling results were evaluated against observed data from the OSPAR Comprehensive Atmospheric Monitoring Programme (CAMP). It was shown that current estimates of long-term trends were comparable with the results of the previous studies. The results of this work were summarized in the Technical Report [Ilyin et al., 2022].
