Origin of tropospheric ozone over central United States. Master's thesis
Ozone (O/sub 3/) is a key species in the troposphere for several reasons. It is a key ingredient of Los Angeles-type smog as a result of photochemical reactions. Tropospheric O/sub 3/ also impacts the radiation budget and may cause climate change because it is a greenhouse gas with a strong absorption band centered at 9.6 um in the atmospheric-window region (Fisherman et. al., 1979). Also, photolysis of O/sub 3/ by radiation of wavelengths less than 318 nm is the primary source of hydroxyl (OH) radicals in the troposphere. Sources of tropospheric O/sub 3/ have been under much debate in the past few days. O/sub 3/ is known to be photochemically active in the stratosphere where it strongly absorbs ultraviolet radiation, causing the reversal in lapse rate there.
