Local Air Quality

Know your air quality. Get the forecast.
Just like the weather, our air quality is forecast every day because there may be elevated levels of air pollution, specifically ozone and particulate matter, which change the outdoor air quality.

The Air Quality Index (AQI) assigns a corresponding color the daily air quality forecast. This was set up so actions that need to be taken for each category can be quickly and effectively communicated to the public, and so that sensitive groups whose health depends on knowing can be alerted.

Good ozone vs. bad ozone
Ozone is good when it is high up in the atmosphere. It protects us from ultraviolet (UV) rays that can be damaging to our skin and other living organisms. Ozone is bad when it is close to the ground where we breathe. Ground-level ozone (smog) is formed through a complex chemical reaction involving hydrocarbons, nitrogen oxides, and the sunlight. High levels of ground-level ozone typically occur on hot, summer days, but can occasionally occur outside of the summer season.

 


Air Pollution Advisory Alerts
An Air Pollution Advisory is issued when air quality data and weather conditions indicate the potential for widespread ozone or fine particulate matter levels at or above the Orange--"Unhealthy for Sensitive Groups" category on the Air Quality Index for multiple days.

As a result of the alert, individuals will know when to take necessary precaution to protect their health and to take action to further reduce contributions to air pollution.
