Modelling and forecasting of atmospheric corrosion processes of the metals establish one of the main uses of the corrosion monitoring. To forecasting of the corrosion changes size both metals and different structural materials were applied the function of dependence of corrosion rates from climatic parameters as well as the level of chosen contaminants in air and precipitation . In the article was described using of data from corrosion monitoring on IMP corrosion sites to modelling and forecasting the corrosion of zinc particularly the editing the corrosion maps of Poland how the chosen areas.
