What do you think when you listen to the morning news and are told the air quality is unhealthy?
from the weather channel…
How is the Air Quality Index calculated?
To measure air quality, networks of monitors record the concentrationsof the major pollutants at more than a thousand locations across theU.S. each day. These raw measurements are then converted into AQIvalues using standard formulas developed by EPA. An AQI value iscalculated for each of the individual pollutants in an area(ground-level ozone, particulate matter, carbon monoxide, sulfurdioxide, and nitrogen dioxide). The pollutant with the highest AQI isused as the overall AQI reading for that day and is listed as theprincipal pollutant.
What do the color codes mean?
EPA has assigned a specific color to each AQI category to make iteasier for people to understand quickly the significance of forecastedair pollution levels in their communities. For example, the colororange means that conditions are “unhealthy for sensitive groups”; thecolor red means that conditions may be “unhealthy” for everyone, and soon.
