The air monitoring station in Finger Lakes State Park tracks exposure to ground-level ozone of people in the Columbia metropolitan statistical area downwind of the city of Columbia. The station monitors attainment of the national ambient air quality standards.

 

 

 

 

 

The federal ozone season runs from March 1 through October 31. Ground-level ozone forms when pollutants emitted by cars, factories, power plants and other sources react chemically in the presence of heat and sunlight. Ozone at ground level is a harmful air pollutant as opposed to ozone in the upper atmosphere, which protects us from ultraviolet light.

As of 2015, the federal standard for ground-level ozone is 70 parts per billion, or 0.070 parts per million. An area is in compliance if the design value is at or below this standard. A design value for ozone incorporates data from three years. The department and EPA calculate the design value by 1) ranking the daily eight-hour ozone values for three consecutive years; 2) extracting the fourth-highest value for each year; and 3) averaging the three figures.
