AirOhio, Air Monitoring Data

This automated air quality data acquisition and reporting system is operated and maintained by Ohio EPA's Division of Air Pollution Control. Some of these air quality reports are in near real-time and a description of their origin follows the selection of currently available reports and our Note and Disclaimer below.

Please select from the following choices:

• Current Air Quality Map
• Air Quality and Your Health
• Air Quality Reports
• Air Quality Index Reports (ozone only) - April through October
• Air Quality Index Forecasts
• Air Pollution Advisory Programs in Ohio
• Pollen and Mold Summaries for Ohio Cities
• Air Monitoring Sites in Ohio
• Air Monitoring Instrumentation
• Contacts and Partners

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.
