During the summer months, more days with higher concentrations of ground-level ozone are reported across the United States. This increase is due to the increased UV radiation during the longer days, which causes emissions to react chemically and produces more ozone.
Here are the solar and UV radiation values from the WeatherSTEM station at a nearby WeatherSTEM unit over the last 72 hours. Based on what you have learned, would you expect ozone levels to be high or low?
