AQI refers to the Air Quality Index. An AQI of 100 is equivalent to the National Ambient Air Quality Standard (NAAQS).
An AQI greater than 100 is considered to be above the national standard or NAAQS.
The weather conditions listed above are common weather types associated with the respective air quality levels.
A combination of part or of all these weather conditions could lead to a certain level of observed air quality. |
