   What is the air quality index based on?

   • The Air Quality Index is based on measurement of particulate matter (PM 2.5 and PM 10 ), Ozone (O 3 ), Nitrogen Dioxide (NO 2 ), Sulfur Dioxide (SO 2) and Carbon Monoxide (CO) emissions. Most of the stations on the map are monitoring both PM 2.5 and PM 10 data, but there are few exceptions where only PM 10 is available.
