A maintenance outage of the EPA’s information network is planned for Memorial Day weekend from Saturday, May 24 at 5:00 AM to Sunday, May 25, at 3:00 AM EST. As a result, AIRNow.gov will be unavailable during this time. However, all files will continue to be processed and products will continue to be generated at the Data Management Center (DMC). All AIRNow products will be backfilled as soon as the maintenance is completed.
Thank you for your attention.
EPA and AIRNow DMC
