ABSTRACT

This technical note is prepared in the framework of cooperation between World Meteorological Organization (WMO), Arctic Monitoring and Assessment Programme (AMAP), and Meteorological Synthesizing Centre East of Co-operative programme for monitoring and evaluation of the long-range transmission of air pollutants in Europe (EMEP/MSC-E). The objective of the work was to develop and test the atmospheric block of a hemispheric transport model to be used for assessment of atmospheric deposition of persistent organic pollutants (POPs) to the Arctic region as a contribution to the relevant AMAP project.

This note presents results of the development of hemispheric multi-compartment model for HMs and POPs, in particular, its atmospheric block. The model uses horizontal resolution of 2.5°x2.5° and 10 non-uniform layers in terrain-following coordinates up to the pressure level of 100 hPa in vertical direction. As a part of this activity the system of meteorological data preparation has been developed. This system provides the meteorological information required for modelling of HM and POP long-range transport within the Northern Hemisphere. Several modelling experiments were carried out using the meteorological information and emission data for 1990. Modelling results were compared with available measurements and with results of MSC-E regional POP transport model.
