Data required for Air Pollution Dispersion Modeling

  • Meteorological conditions such as wind speed and direction, the amount of atmospheric turbulence (as characterized by what is called the \"stability class\"), the ambient air temperature, the height to the bottom of any inversion aloft that may be present, cloud cover and solar radiation.
  • Source term (the concentration or quantity of toxins in emission or accidental release source terms) and temperature of the material
  • Emissions or release parameters such as source location and height, type of source (i.e., fire, pool or vent stack)and exit velocity, exit temperature and mass flow rate or release rate.
  • Terrain elevations at the source location and at the receptor location(s), such as nearby homes, schools, businesses and hospitals.
  • The location, height and width of any obstructions (such as buildings or other structures) in the path of the emitted gaseous plume, surface roughness or the use of a more generic parameter \"rural\" or \"city\" terrain.
