Damage to materials is one of the concerns of the National Acid Precipitation Assessment Program (NAPAP). The project addressed the concern by providing an inexpensive method for estimating the deposition of hydrogen ions and sulfur dioxide on spatial scales compatible with materials distributions within urban areas. Since monitoring data are taken at only a few discrete points within any urban area the direct use of such data was rejected as unsuitable for meeting the concern. Comparison of output from the Parameterized Air Quality Model Annual (PAQMAN) developed earlier in this project shows that the model values are generally within a factor of two of the observations. The model is sensitive to the size of the emissions grid cells especially in the 1 to 2 km size range. The most suitable use for PAQMAN is as a rapid screening technique for examining the effect of thousands of point sources of sulfur dioxide across an extensive region. Some of the automated procedures developed for PAQMAN have wider application.
