| Abstract | The Regional Acid Deposition Model, RADM, an advanced Eulerian model, is used to develop an estimate of the primary airshed of nitrogen oxide (NOx) emissions that is contributing nitrogen deposition to the Chesapeake Bay watershed. A brief description of RADM together with a summary of the aggregation method used to develop annual average deposition is given. The evaluation background of RADM is summarized. The transport range of the nitrogen affecting deposition, principally the termination product nitric acid, is first established in the model. This range is compared to that determined for sulfur. |
