Default Forecasts - Additional NOAA model options now available!

NOAA and NOAA Bias-Corrected air quality model forecasts for PM2.5 and Ozone are now available as default forecast options within the AirNow-Tech Forecast Submittal System.

These settings can be configured by forecasters under the Forecasts->Settings tab within AirNow-Tech, within the "Default Forecast" box.

When default forecasts are enabled for a reporting area, same-day and next-day forecasts will be issued automatically at 4:15 PM eastern time using the chosen default forecast option. NOAA model options will use the latest 12Z model run.

If you have any additional questions, please contact dmc@airnowtech.org. Thank you.
