I-Air Quality Index (AQI) iwukubonakaliswa kwamazinga okugcwala kokungcola komoya. Ibeka izinombolo esikalini esiphakathi kuka-0 no-500 futhi isetshenziselwa ukusiza ekunqumeni ukuthi ikhwalithi yomoya kulindeleke ukuthi ingabi nempilo nini.
Ngokusekelwe ezindinganisweni zekhwalithi yomoya kahulumeni, i-AQI ifaka phakathi izindlela eziyisithupha ezinkulu zokungcola komoya: i-ozone, i-carbon monoxide, i-nitrogen dioxide, i-sulfur dioxide, kanye nosayizi ababili wezinto ezincane. E-Bay Area, izinto ezingcolisayo ezingase zibangele i-Spare the Air Alert yi-ozone, phakathi kuka-Ephreli no-Okthoba, kanye nezinto ezincane, phakathi kukaNovemba noFebhuwari.
Inombolo ngayinye ye-AQI ibhekisela enanini elithile lokungcola emoyeni. Eziningi zezingxenye eziyisithupha ezingcolisayo ezimelelwa yishadi le-AQI, indinganiso kahulumeni ihambisana nenani elingu-100. Uma ukugcwala kokungcola kukhuphuka ngaphezu kuka-100, ikhwalithi yomoya ingaba yingozi emphakathini.

Ukufundwa okungaphansi kuka-100 ku-AQI akufanele kuthinte impilo yomphakathi jikelele, yize ukufundwa okuphakathi kuka-50 no-100 kungathinta abantu abazwela kakhulu. Amazinga angaphezu kuka-300 awavamile ukwenzeka e-United States.
Lapho i-Air District ilungiselela isibikezelo sansuku zonke se-AQI, ilinganisa ukuhlushwa okulindelekile kwengcoliswa ngayinye kweziyisithupha ezinkulu ezifakiwe ku-index, iguqula ukufundwa kube izinombolo ze-AQI, futhi ibike inombolo ephezulu kakhulu ye-AQI yendawo ngayinye yokubika. Isaziso Sokuphepha Komoya sibizwa nge-Bay Area lapho ikhwalithi yomoya kulindeleke ukuthi ingabi nempilo kunoma yiziphi izindawo ezinhlanu zokubika zesifunda.
