Notice regarding new AirNow sites

Dear AirNow-Tech users,

Due to a large number of new international sites coming into AirNow and the increasing possibility of duplicate 9 digit site ID’s, we have prepended the 3 digit country code (840 for the U.S.) to all new sites coming into the system as of June 2018. If your agency is adding new sites, a 12 digit site code in your site list is the expected behavior.

Sites that existed prior to June 2018 had back-end adjustments made to ensure they are kept separate from international sites with the same 9 digit code.

Please send any questions or concerns to AirNowInfo@sonomatech.com.

Thank you, AirNow Data Management Center
