Ozone Monitoring
During ozone season (April 1st to October 31st, each year), the air quality group, through a contractor, operates and maintains six continuous ozone monitoring stations located in the CAPCOG planning region. The objective of operating these monitors is to collect data on the following:
- Ground-level ozone concentrations (ppb)
- Ozone precursor concentrations - Nitrogen Oxides (NOx)
- Sulfur Dioxide (SO2)
- Carbon Monoxide (CO)
- Meteorological data: wind direction, wind speed, and ambient temperature
The data obtained from the CAPCOG monitors compliment existing Texas Commission on Environmental Quality (TCEQ) monitoring data for the Austin-Round Rock Metropolitan Statistical Area. The TCEQ operates two regulatory monitors that are used to determine compliance with the ozone National Ambient Air Quality Standards (NAAQS).
