Abstract By collecting and organizing 46 ozone sounding data from November 24,2021 to October 5,2022 in the Beijing area,the vertical distribution of high-resolution ozone partial pressure data from the ground to around 35 km within one year was obtained.The distribution and trend of ozone in the troposphere and stratosphere were analyzed,with a focus on in-depth research on the seasonal variation of ozone profiles and the vertical distribution characteristics of low boundary layer ozone.The stability of ozone sounding instruments and equipment was verified.The results showed that there was a significant difference in ozone mass concentration between 25-40 km,and the ozone mass concentration was highest in autumn.The vertical distribution characteristic of ozone in the low boundary layer is characterized by the highest proportion of "uniform type",and when the air quality is mildly polluted by ozone,the profile distribution is almost always decreasing.
