The main source of spatial information on concentration and deposition of air pollutants in Poland is the continental scale EMEP model with 50km x 50km grid. The coarse resolution of the EMEP model may be insufficient for regional scale studies. A new proposal is the application of the national scale atmospheric transport model FRAME (Fine Resolution Atmospheric Multi-pollutant Exchange), originally developed for the United Kingdom. The model works with 5km x 5km spatial resolution and the air column is divided into 33 layers. FRAME was used here to asses the spatial patterns of yearly averaged air concentrations, and wet and dry deposition of sulphur and nitrogen compounds for the area of Poland. This study presents preliminary results of the modelling of the yearly average concentrations as well as dry and wet deposition of SOx, NOy and NHx for Poland. FRAME results were compared with available measurements from the monitoring sites and national deposition budget with the EMEP and IMGW estimates. The results show close agreement with the measured concentrations expressed by determination coefficient close to 0.7 for both SO2 and NOx. The dry and wet deposition budgets for FRAME are also in close agreement with the EMEP and GIOŚ estimates. The FRAME model, despite its relatively simple meteorological parameterisations, is well suited to calculate the spatial pattern of annual average concentration and yearly deposition of atmospheric pollutants which was earlier presented for the UK and was shown in this paper for Poland. The model can also be used to analyse the impact of individual point sources or different emission sectors on spatial pattern of air concentration and deposition as well as testing the changes in deposition resulting from future emissions reduction scenarios.
