RISSensitivity of Urban Airshed Model (UAM-IV) Calculated Air Pollutant Concentrations to the Vertical Diffusion Parameterization during Convective Meteorological Situations
Publisher: American Meteorological Society
Abstract: It is shown that Urban Airshed Model (UAM-IV) calculated air pollutant concentrations during photochemical smog episodes in Atlanta, Georgia, depend strongly on the numerical parameterization of the daytime vertical ...
A Meteorology-Based Approach to Detecting the Relationship between Changes in SO2 Emission Rates and Precipitation Concentrations of Sulfate
Publisher: American Meteorological Society
Abstract: In this paper, the authors present an analysis of correlations between SO2 emissions and wet SO2?4 concentrations over eastern North America that includes adjustments for the impact of meteorological variability. The ...
Aggregation of Selected Three-Day Periods to Estimate Annual and Seasonal Wet Deposition Totals for Sulfate, Nitrate, and Acidity. Part II: Selection of Events, Deposition Totals, and Source Receptor Relationships
Publisher: American Meteorological Society
Abstract: A method for deriving estimates of long-term acidic deposition over eastern North America based on a limited number of Regional Acid Deposition Model runs has been developed. The main components of this method are the ...
Aggregation of Selected Three-Day Periods to Estimate Annual and Seasonal Wet Deposition Totals for Sulfate, Nitrate, and Acidity. Part I: A Synoptic and Chemical Climatology for Eastern North America
Publisher: American Meteorological Society
Abstract: Running 3-day periods from 1979 to 1985 were categorised into one of 20 meteorological categories. These categories were developed through the cluster analysis of 3-day progressions of 85-kPa wind flow over eastern North ...
