AirNow Milestone

The AirNow Program reached an important milestone last week when the number of data records in the AirNow database reached 1 billion. This number is growing at a rate of about 45,000 data records an hour. The rate is expected to increase as automated syncing of Air Quality System (AQS) data begins in a few weeks.

Other AirNow statistics:

Number of Forecast Cities/Reporting Area: 443

Number of Monitoring Sites Reporting Data: 2,483

Number of Agencies Submitting Data: 129
