Abstract During the summer of 1987 annual amounts of sulfur dry deposition were first estimated for more than 7,000 lakes in the northeastern United States. These estimates, heretofore termed interim estimates since they were expected to be superceded in the near future, were derived from predictions of the Regional Acid Deposition Model (RADM) adjusted using the empirical data from two monitoring networks. In the report the authors compare the dry deposition predictions from the three models (RADM, RELMAP and ASTRAP) to the available empirically-derived estimates to ascertain which of these models most accurately represents the spatial pattern of sulfur dry deposition. Using one of these models in conjunction with the available data, they then recommend systematic revisions to the interim estimates. The uncertainty and bias in these revised estimates are characterized relative to interannual variability in the empirically-estimated amounts of sulfur dry deposition, and distance of sites from the emission source regions.
