Real-time Air Advisory Network

Thanks for using RAAN! Please note the following:

New Interface!!

The Valley Air District has launched a new RAAN interface which provides air quality based on location within the San Joaquin Valley. Look up any address that you wish to view, save locations & get notifications!

Used to the old system? We will still temporarily offer access to our original RAAN info page which provides air quality data based on the location of our air monitors and Valley schools.
