Title: Vertical Distribution of Stratospheric Ozone over China
Abstract: Based on the Stratospheric Aerosol and Gas Experiment (SAGE) II and the Halogen Occultation Ex-periment (HALOE) ozone profiles and the Total Ozone Mapping Spectrometer (TOMS) total ozone data sets,the characteristics and variations of the vertical distribution of stratospheric ozone covering the latitude bands of 50oN±5oN,40oN±5oN,30oN±5oN,and 20oN±5oN and the longitude range of 75-135oE are investigated.The results indicate that the ozone distribution pattern over China not only has general behaviors,but also has particular char-acteristics.In view of the situation that ozone distribu-tions have substantial deviation from zonal symmetry in northern China,the differences of the vertical ozone dis-tribution between the east and the west part of northern China are studied.The results indicate that during winter,spring,and autumn,in the latitude bands of 50oN±5oN,40oN±5oN,ozone concentrations in the eastern part (105 -135oE) are obviously higher than those of the west (75-105oE) at the altitudes of ozone density maximum and below;during summer,in the latitude band of 50oN±5oN,the east-west ozone profile difference is small,but in the latitude band of 40oN±5oN,the east-west total ozone difference becomes as large as 14.0 DU,and the east-west ozone profile difference mainly exists in the lowermost stratosphere and troposphere.
