Data Capture 

The Southwest Ohio Air Quality Agency has an air monitoring network of 58 samplers located at 18 monitoring sites throughout Hamilton, Butler, Clermont, Clinton, and Warren counties. In 2018 alone, the monitoring network generated 332,431 hours of valid monitoring data for critical pollutants including ozone, particulate matter, and nitrogen dioxide.

The Agency achieved a 97% capture rate in 2018 for all required monitors combined; the requirement set by U.S. EPA is 75%. That means that 97% of all possible hours or days of air monitoring data collected by the Agency were valid and reported to the national database. For the first two quarters of 2019, the capture rate for particulate matter is 99%. The ozone capture rate for March through June of 2019 is 98% (ozone monitoring begins March 1 each year). 

monitorOur Monitoring and Analysis team includes technicians in the field, analysts in the laboratory, and managers reviewing incoming data and reports daily; all contribute to the exacting work of collecting, analyzing, and reporting air quality data. A great deal of individual effort and teamwork is invested in keeping the complex monitoring network running, 24 hours a day, 365 days a year. Technicians and managers monitor the incoming data each day to identify potential issues and prioritize daily tasks. Each monitoring site is visited by technicians at least once a week to conduct routine checks and maintenance. Some data loss is inevitable due to required checks, occasional power outages, mechanical issues, and even wildlife interference. Something as simple as a spider building a web in a gaseous intake line could invalidate data.  Our team takes a proactive approach to identify potential problems early in order to prevent data invalidation when possible, and to minimize unnecessary downtime.

The Southwest Ohio Air Quality Agency team prides itself in maintaining an excellent capture rate for the benefit of U.S. EPA and Ohio EPA, as well as the public.

You may view hourly and daily air quality data on the Agency’s website, via the Air Quality Map and the Concentration Chart. If you have any questions about the work we do here at the Agency, reach out with our Contact Us form.
