Vertical distribution of atmospheric ozone in Hangzhou Region
By using the domestic ECC ozonesonde to conduct one year(December 2021 to November 2022)measurements in Hangzhou,this paper investigated the characteristics of vertical ozone distribution,total column ozone and tropospheric column ozone,and evaluated the ozone profile products retrieved from the Atmospheric Infrared Sounder(AIRS)onboard the Aqua satellite and Microwave Limb Sounder(MLS)onboard the Aura satellite,and also compared the total column ozone products retrieved from AIRS,OMI DOAS and TROPOMI.The results indicated a high consistency of surface ozone measurements between the ozonesonde and ground-based ozone analyzer.The vertical ozone structure exhibited significant monthly variation in Hangzhou.A descending structure of high ozone transmission was observed in the upper troposphere-lower stratosphere region(12～16km)in May,and a high ozone content layer was observed in the boundary layer below 1.5km from April to September.The ozone concentration in the boundary layer was highest in summer,with inconspicuous vertical variation,which was followed by that in spring,autumn and winter when the ozone concentration increased with the increase of height.The ozonesonde measurements and satellite retrievals showed similar variability in the vertical ozone profiles,with a relative difference mostly<10%in the height range analyzed.The average total column ozone and tropospheric column ozone were 302.1DU and 40.5DU,respectively,which showed obviously seasonal variation.The total column ozone and the tropospheric column ozone were highest in spring and summer,respectively,and the tropospheric column ozone was highest in May.The total column ozone from ozonesonde measurements showed a good agreement with the products retrieved by AIRS,OMI DOAS and TROPOMI,with correlation coefficients of 0.78,0.88,and 0.76,respectively.
