What is a key strategy for reducing ozone-depleting emissions from industrial processes?
Who is monitoring and where?
Ozone monitoring data are collected in or near 102 national parks! NPS staff and partners operate the monitors in 36 of these locations. Across the United States ozone monitoring is conducted by the Environmental Protection Agency (EPA), states, and other agencies.
These groups and the NPS contribute to a nation-wide ozone monitoring network by observing common standards and reporting requirements. EPA’s Clean Air Status and Trends Network (CASTNET) is largely responsible for site audits and data are reported to the EPA Air Quality System (AQS).
How to measure ozone levels at homeWhen selecting ozone monitoring locations the NPS considers:
- Air quality concerns
- Regional representation
- Data gaps
Several national parks also use ozone gardens to monitor the ecological effects of ozone on sensitive plant species.
How often do we measure?
Ozone data are collected continuously (1-minute averages) and reported in one-hour intervals. Because ozone is not stable, it must be measured onsite to accurately determine its concentration in the atmosphere.
This also allows us to provide rea
