主　　题：Ozone profiles EMI Soft calibration Floor noise correction Stratospheric ozone intrusion 

摘      要：Understanding the vertical distribution of ozone is crucial when assessing both its horizontal and vertical transport,as well as when analyzing the physical and chemical properties of the *** of the most effective ways to obtain high spatial resolution ozone profiles is through satellite *** Environmental Trace Gases Monitoring Instrument(EMI)deployed on the Gaofen-5 satellite is the first Chinese ultraviolet-visible hyperspectral ***,retrieving ozone profiles using backscattered radiance values measured by the EMI is challenging due to unavailable measurement errors and a low signal-to-noise *** algorithm developed for the Tropospheric Monitoring Instrument did not allow us to retrieve 87%of the EMI ***,we developed an algorithm specific to the characteristics of the *** fitting residuals are smaller than 0.3%in most *** retrieved ozone profiles were in good agreement with ozonesonde data,with maximum mean biases of 20%at five latitude *** applying EMI averaging kernels to the ozonesonde profiles,the integrated stratospheric column ozone and tropospheric column ozone also showed excellent agreement with ozonesonde data,The lower layers(0-7.5 km)of the EMI ozone profiles reflected the seasonal variation in surface ozone derived from the China National Environmental Monitoring Center(CNEMC).However,the upper layers(9.7-16.7 km)of the ozone profiles show different trends,with the ozone peak occurring at an altitude of 9.7-16.7 km in March,2019.A stratospheric intrusion event in central China from August 11 to 15,2019,is captured using the EMI ozone profiles,potential vorticity data,and relative humidity *** increase in the CNEMC ozone co ncentration showed that downward transport enhanced surface ozone pollution.
