Field measurements of O3 and N2O produced from corona discharge

Presented here are the results from a field study concerning the measurement of O 3 and N 2 O produced by corona discharge from a grounded metal tube with a sharp point during thunderstorms. We observed as much as a tenfold increase in the 03 concentration as well as a four percent increase in the N 2 O concentration as a result of corona discharge. The concentrations of both O 3 and N 2 O returned to the original ambient levels after the thunderstorm ended.
