Transition of AirNow Stakeholder Support

On September 29, 2020, the AirNow system will move to a new technical support team* and hosting environment for the operation of the AirNow Data Management Center (DMC). We fully expect that the new team will continue to provide the level of support needed to operate and improve this vital program.

We recognize that many of you are still facing wildfire smoke in your jurisdictions, and we will do everything possible to minimize disruption during this transition. While we don’t anticipate any extended downtime, you may notice 1 or 2 hours of missing data or services. If you notice any issues, or if you have questions about this change, please contact the AirNow team at AirNowQuestions@epa.gov.

After September 29, the AirNow support team will have new email addresses. Please use the following:

For AirNow operational or data issues: dmc@AirNowTech.org

For general information about AirNow data, systems or applications: info@AirNowTech.org

For EnviroFlash questions or issues: enviroflash@AirNowTech.org **

For AirNow mobile app questions or issues: app@AirNowTech.org

For AirNow Application Program Interface (API) questions or issues: api@AirNowTech.org

*Tantus Technologies Inc., Attain Inc., TD Environmental Services, Gold Systems, and University of North Carolina

**All outgoing EnviroFlash emails will be sent from this email address
