Access and Use Constraints

Note: Data in these reports are always referenced to Eastern Standard Time (EST). Air Quality Index reports are updated several times during a day at regular intervals (generally 15 or 30 minutes past the hour or hourly from 8 a.m. - 10 p.m.).

Disclaimer: These reports present the data in "RAW" form, meaning that the data you see are exactly what was collected electronically from each pollution monitor several times during each day. It is important to remember that "RAW" data are never considered valid until verified by Ohio EPA and Local Air Agency personnel.

The data in these reports have neither been validated nor quality assured by state or local air monitoring agencies. These data may change and are not considered official until they have undergone a quality assurance/quality control (QA/QC) review.

Odd data are suspected invalid due to possible equipment trouble or telemetry problems.
