✦ Synopsis

Atmospheric transport and deposition of SO2 are simulated over a circular area (22 km in radius) of representative landscape in East Tennessee. Data from aerial photographs were used to determine surface parameters which in turn allowed us to estimate deposition rates on the different ground cover types by taking account of both aerodynamic and surface related components of the process. Patterns of deposition rates are shown and are compared with spatial patterns of ground cover type. Area averaged values of deposition velocity are deduced for representative times of the year. We speculate on the influence of various physical factors as they bear upon the perceived sensitivity of different species to SO2 damage.
