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).
