Analysis of vertical distribution differences of global stratospheric ozone based on weighted multiplication algebraic algorithm br

Global climate change and the formation of the Antarctic ozone hole have prompted people to payattention to the changes in atmospheric ozone content. The global continuous observation of ozone is achievedby retrieving the global total column concentration from nadir satellite data. In this work, the weightedmultiplication algebraic algorithm is combined with the radiative transfer model SCIATRAN, by using the 2011Chappuis-Wulf band SCIAMACHY limb radiation data to retrieve the stratospheric ozone profile between15- and 40 km altitude, solving the ozone global stratified observation problems. In the ozone globalstratification map, the whole process of the global transmission of ozone formed in low latitude regions to highlatitude regions is observed, which is directly related to the Brewer-Dobson circulation. During the most severeperiod of the Antarctic ozone hole from September to October, the Antarctic polar vortex has an obvioushindering effect on ozone transmission, and the polar vortex has a "transparent wall" effect. On the one hand, itis difficult to transfer ozone from the equatorial region to the Antarctic region for replenishment. On the otherhand, the retention of ozone-depleting substances over the Antarctic region leads to the acceleration of ozonedepletion, and the combination of low replenishment and high depletion contributes to the Antarctic ozone hole.Compared with the global total column concentration of ozone, the observation of global ozone stratification isvery valuable for scientific research and will promote the detailed study of the whole process of ozone formation, transmission, and consumption
