Winter ozone will likely exceed the EPA standard on Wednesday and Thursday and citizens are encouraged to take action to reduce ozone-forming emissions. “We underestimated ozone all last week,” shares Dr. Seth Lyman, Director of the USU Bingham Research Center. “Every day we predicted that on the next day the atmosphere would mix out and the basin would be clean again, and it really didn’t fully happen
until Saturday
. We are in much the same situation this week.” Dr. Lyman explains that the snow cover and sunlight this late in the season had ozone building to about 68 ppb(parts per billion) at Ouray on Tuesday. Right now their best guess is that the storms will keep ozone lower than it would be but that the storms will also not be able to mix away the inversion and clean out the atmosphere.
