How do I add a new forecast city or reporting area to AirNow?

Email AirNowInfo@sonomatech.com with the following information for each new forecast city or reporting area:

  • Name of the forecast city or reporting area.
  • Central coordinates (latitude and longitude) that are representative of the forecast area. The coordinates of a centrally located monitoring site can often be used.
  • If forecasts will be issued, will they be issued year-round or seasonally?
  • Is there an air quality action day program? If yes, what is the name of the program?

Once a new forecast city or reporting area has been added, you will be notified and asked to review the assigned verification monitoring sites and zip codes.
