Meteorology and Air Quality

Influence of Meteorology

Air quality depends on the rate that pollutants are emitted to the atmosphere and the rate at which these pollutants are dispersed away from the sources. Air pollution transport and dispersion are influenced by wind speed and direction, the temperature structure of the atmosphere, the solar cycle, turbulence, precipitation and changes in these elements induced by local topography.

Precipitation may remove pollutants from the atmosphere, depositing them on soils and vegetation. Rates of deposition of pollutant gases are highest when vegetation and soils are wet. Vegetation is more susceptible to damage during periods of highest growth.

Monitoring Program

Meteorlogical parameters measured in support of the West Central Airshed Society air quality monitoring program are:

  • wind speed and direction
  • temperature
  • difference in temperature a two heights
  • solar radiation
  • photosynthetically active radiation
  • amount of precipitation
  • relative humidity
  • surface wetness

Precipitation samples are also collected and chemically analyzed for acidity and major constituents.
