The Air Quality Index (AQI) is an index for reporting daily air quality. It was created as an easy way to correlate levels of different pollutants to one scale; the higher the AQI value, the greater the health concern. When levels of ozone and/or fine particles are expected to exceed an AQI value of 100, an Air Quality Health Advisory is issued alerting sensitive groups to take the necessary precautions.
Here is the quick reference guide for New York State's Air Quality Index (AQI) Forecast and Current Observations:
The Air Quality Forecast displays the predicted maximum Air Quality Index value for eight Air Quality Health Advisory regions in New York State. It also displays the observed maximum values for the previous day. DEC's Air Quality Health Advisory regions. Air quality measurements from the DEC's statewide continuous monitoring network are updated hourly where available. Parameters monitored include ozone, fine particulate, carbon monoxide, sulfur dioxide, nitrogen oxides, methane/nonmethane hydrocarbons, and meteorological data.
