Abstract |
Precipitation chemistry measurements over a network of samplers upwind and downwind of Philadelphia, PA show that a major contribution of the local sources can be discerned under certain conditions. For winter frontal storms with low level winds from the south east, up to as much as a factor of two increase over upwind values has been observed for downwind nitrate deposition. Sulfate deposition shows an increase of about a factor of one and one half. The nitrate deposition increases toward the downwind direction away from the urban-industrial sources, indicating that the maximum is likely to have been beyond the sampling network for these case studies. One storm had no increase in nitrate or sulfate deposition but did have an increase in total sulfur content in the precipitation. Reasons for this difference are being sought. |
