摘　　要：利用国产双池型电化学反应臭氧探空仪在杭州开展为期1年(2021年12月~2022年11月)观测,分析了该地区臭氧廓线垂直分布、臭氧柱总量以及对流层臭氧柱含量特征,并评估AIRS和MLS反演的臭氧廓线产品以及AIRS、OMIDOAS和TROPOMI反演的臭氧柱总量产品.结果表明,臭氧探空仪与地面原位臭氧分析仪观测结果具有高一致性.杭州地区臭氧垂直结构呈显著月变化特征,5月在上对流层-下平流层区域(12~16km高度范围)呈现高浓度臭氧的下传结构.4~9月在边界层附近1.5km高度以下观测到高浓度臭氧含量层.边界层内臭氧含量夏季最高,垂直变化不明显;其次是春季、秋季和冬季,均表现为随高度增加而增大.臭氧探空廓线与卫星反演臭氧垂直廓线吻合较好,在对比高度范围内相对偏差大多<10%.杭州地区臭氧柱总量和对流层柱含量平均值分别为302.1DU和40.5DU,呈明显季节变化特征.臭氧柱总量和对流层柱含量最高的季节分别为春季和夏季,5月对流层臭氧柱含量最高.臭氧探空柱总量与AIRS、OMI DOAS和TROPOMI反演臭氧柱总量一致性较好,相关系数分别为0.78、0.88和0.76.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.
