Caution: Data is not validated

Note: PM-2.5 data is measured by a non-reference method and should be considered an estimate

For data comparision purposes, the ambient air quality standards are:

  • Sulfur Dioxide (SO2):
    • 3 hour = 500 parts per billion
    • 24 hour = 140 parts per billion
    • Annual Mean = 30 parts per billion
  • Ozone (O3):
    • 1 hour = 125 parts per billion (The revocation of the 1-hour Ozone NAAQS, 125 parts per million, was effective on June 15, 2005)
    • 8 hour = 75 parts per billion
  • Nitrogen Oxides (NOx): no standard
  • Nitrogen Dioxide (NO2): Annual Mean = 50 parts per billion
  • Carbon Monoxide (CO):
    • 1 hour = 35.0 parts per million
    • 8 hour = 9.0 parts per million
  • Hydrogen Sulfide (H2S):
    • 1 hour = 100 parts per billion
    • 24 hour = 5 parts per billion
  • PM-10:
    • 24 hour = 150 micrograms per cubic meter
  • PM-2.5:
    • 24 hour = 35 micrograms per cubic meter
    • Annual Mean = 15 micrograms per cubic meter

Weather Measurement Definitions

  • AT = Ambient (Outside) Temperature (degrees Farenheit)
  • SR = Solar Radiation (watts per square meter) indicates amount of sunshine
  • SWS = Scalar Arithmetic Averaged Wind Speed (miles per hour)
  • VWS = Vector Averaged Wind Speed (miles per hour)
  • VWD = Vector Averaged Wind Direction (compass degrees where 0=north, 90=east, 180=south, 270=west)
