AB  - The introduction of the global O3 dataset is global three-dimensional (longitude, latitude, altitude) ozone data. The production of this dataset uses ozone sounding data observed at 392 stations around the world. Among them are ozone vertical distribution data observed by 141 ozone sonde stations, including the World Ozone and Ultraviolet Radiation Data Centre (WOUDC) and the Southern Hemisphere ADDITIONAL OZonesondes (SHADOZ) data sets. In addition, 251 In-service Aircraft for a Global Observing System (IAGOS) aircraft observed ozone vertical sounding data. The data set is mapped from global ozone detection records through trajectory mapping. In order to make the space wider, 96 hours of forward and backward trajectory calculations were used to map ozone measurements to other locations at 1-kilometer altitude intervals. The backward trajectory is calculated using version 4.8 of the HYSPLIT model developed by the NOAA Air Resources Laboratory (NOAAARL). The meteorological input to the orbit model is the global NOAA-NCEP/NCAR (National Center for Environmental Prediction/National Center for Atmospheric Research) pressure level reanalysis data set. The horizontal resolution of the global O3 dataset is 2°×2° and the vertical resolution is 1km. There are 26 layers in the vertical direction, in ppbv, and the time period is 1990-2022. WOUDC is one of six world data centers of the World Meteorological Organization's (WMO) Global Atmosphere Watch Programme (GAW). The WOUDC Data Center is operated by the Canadian Meteorological Agency, a branch of the Canada Environment and Climate Change Section. The observation time of WOUDC data used in this dataset is from 1990 to 2022. The measurement instruments for WOUDC O3 sounding data mainly consist of four types: the brewer-mast detector, the Indian-sonde detector, the Electrochemical Concentration Cell (ECC) detector and the carbon-iodine detector. The most important measurement instruments are the ECC and Brewer-Mast(BM) detecto
