Parameters

A Parameter in the OpenAQ platform is the type of particle or gaseous pollutant measured.

Currently OpenAQ supports the following Parameters:

  • PM2.5 - Particulate matter smaller than 2.5 microns
    • mass concentration (i.e. µg/m³)
    • count (i.e. particles/cm³ )
  • PM4 - Particulate matter smaller than 4 microns
    • mass concentration (i.e. µg/m³)
    • count (i.e. particles/cm³ )
  • PM10- Particulate matter smaller than 10 microns
    • mass concentration (i.e. µg/m³)
    • count (i.e. particles/cm³ )
  • NO - Nitrogen Monoxide
  • NO₂ - Nitrogen Dioxide
  • CH₄ - Methane
    • Concentration (i.e. ppm)
  • SO₂ - Sulfur Dioxide
  • O₃ - Ozone
  • CO - Carbon Monoxide
  • BC - Black Carbon
