Other Ozone Destruction Processes
qOther atmospheric trace constituents, such as
nitrous oxide (N2O), water vapor, and freons, can also be photolyzed. They produce
highly reactive radicals that keep ozone abundances lower than they would otherwise
be.
qThese radicals include: nitric oxide (NO), atomic
chlorine (Cl), bromine (Br) radicals, and hydroxyl (OH) radicals.
qThese radicals can destroy stratospheric ozone
through “catalytic cycles”.
