Abstract
The paper contains the description of numerical model of the airborne pollution transport developed by a scientific team of M. Galperin. During several years the model was used for the calculations in Meteorological Synthesizing Centre – East, within the scope of Co-operational Programme for Monitoring and Evaluation of the Long-Range Transmission of air Pollutants in Europe (EMEP). The paper presents the extensive description of the current version of the model and outlines the results of its quality assurance. The model is based on an original Eulerian advection scheme with variable time step, which can be classified as a “pseudo-Lagrangian” scheme. Vertical concentration profiles are parameterized by truncated Gaussian function with dynamic parameters calculated at every model time step. The model includes two types of chemistry and deposition units: acid compounds and ammonia, and heavy metals carried with aerosol particles. One of the model advantages is the ability to make the evaluation of source–receptor pollution exchange for substances with non-linear atmospheric chemistry and deposition. The model evaluation was carried out by the comparison of multi-annual calculated concentrations with measured values for several acidifying substances.
