AirNow API FTP is Moving!

The AirNow Data Management Center (DMC) will be moving all files currently located on the FTP server (ftp://ftp.airnowapi.org/ ) to our new location:

https://files.airnowtech.org/

Please make appropriate changes to any processes that utilize AirNow API file products and direct them to the new location.

This change will not effect the file transfer process into AirNow, ftp.airnowdata.org will remain intact

If you have any questions, please send them to AirNowInfo@sonomatech.com.

Thank you for your attention.
