This study presents a case-based evaluation of Geostationary Environment Monitoring Spectrometer (GEMS) ozone products using daily ozonesonde measurements during pre-ACCLIP (2021) and ACCLIP (2022) campaigns. The analysis uses a total of 62 ozonesonde profiles along with atmospheric reanalysis to better understand daily ozone variability and circulation change related to the Asian summer monsoon. The new GEMS ozone profile (version 3) product successfully captures significant variability in tropospheric and lower stratospheric ozone, including major stratospheric ozone intrusion in 2021 and storm-induced tropospheric ozone decreases in 2022. These variations were closely related to convective activities associated with the Asian monsoon rainband and strong anticyclones in the upper troposphere and lower stratosphere. The comparison between ozonesonde data and GEMS ozone products demonstrates GEMS's capability to detect these dynamic ozone variations, highlighting its potential in monitoring chemical transport and regional-scale air quality in Asia.
