Origin of Tropospheric Ozone over Central United States
Abstract
Ozone (O3) 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 O3 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 micro m in the atmospheric window region (Fisherman et. al., 1979). Also, photolysis of O3 by radiation of wavelengths less than 318 nm is the primary source of hydroxyl (OH) radicals in the troposphere. Sources of tropospheric O3 have been under much debate in the past few days. O3 is known to be photochemically active in the stratosphere where it strongly absorbs ultraviolet radiation, causing the reversal in lapse rate there.
