  • PM10 - particulate matter up to 10 micrometers from traffic and industry
  • NO2 - nitrogen dioxide mainly emitted by vehicles
  • O3 - tropospheric ozone formed in photochemical reactions

When is Air Quality Best in Klahanie?

Generally, the best air quality occurs:

  • Early morning (5:00-7:00 AM) before rush hour traffic
