Abstract
A three-dimensional Eulerian model with simplified sulfur chemistry (TSEM) has been developed to examine source-receptor relationships and the response of sulfate deposition to hypothetical control strategies for sulfur dioxide source emissions. Archived output files from a comprehensive Eulerian model (the Regional Acid Deposition Model) are used to provide necessary chemical inputs. Results from comparisons of the simplified model with the comprehensive model show that TSEM represents sulfate deposition very well both for base case emissions and for a hypothetical 50% reduction in all sulfur-emitting sources. Source-receptor relationships are exhibited by means of taggedsulfur emissions, as illustrated in two examples.
