Temporal and latitudinal variations of stratospheric trace gases - A critical comparison between theory and experiment

摘要: Global calculations of stratospheric HOx, Clx, and NOx are presented which include the effects planetary albedo diurnal seasonal variations insolation. Comparisons made with a wide range atmospheric measurements at different latitudes altitudes. Agreement between theory observations is generally within factor 2. The appears to explain adequately major features latitude distributions NO2 HNO3. results indicate that mesospheric OH makes an appreciable contribution total column abundance strongly suggest nitrogen oxides exist principally in form HNO3 high winter. There difficulties reconciling OH, ClO, O3 upper stratosphere.
