Atmospheric and Ozone Profiling Data Measured with Ozonesonde from 2021 to 2024

From 2021 to 2024, balloon-borne in-situ observations were conducted to study the vertical ozone distribution over the Korean Peninsula. The electrochemical concentration cell (ECC) ozonesondes that produce high-resolution ozone profiles from the surface to 30 km based on balloon sounding and KI redox reactions were used, and a total of 123 ozone profiles were produced at Anmyeon, Osan, and Yongin sites. Consecutive daily measurements were made at the Anmyeon site, focusing on ozone transport processes through the Asian summer monsoon. Twice a day (AM, PM) measurements were done at the Yongin site to understand the diurnal cycle of ozone due to photochemical reactions and vertical transport. The ozone data were integrated into netCDF for each measurement year and location, along with the atmospheric profiles of temperature, pressure, humidity, and wind from radiosonde. The ECC ozonesonde provides ozone information with reference-level accuracy, and the data could be further used to improve satellite- and model-based ozone products.
