Evaluation of Total Ozone Column from Multiple Satellite Measurements in the Antarctic Using the Brewer Spectrophotometer

The ground-based ozone observation instrument, Brewer spectrophotometer (Brewer), was used to evaluate the quality of total column (TOC) produced by multiple polar-orbit satellite measurements at three stations in Antarctica (King Sejong, Jang Bogo, and Zhongshan stations). While all TOCs showed high correlations with (R = ~0.8 0.9), there are some TOC differences among data austral spring, which is mainly attributed bias Atmospheric Infrared Sounder (AIRS) TOC. consistent between Level 2 3 data, implying that “which used” can induce larger uncertainty than spatial resolution for investigation Antarctic pattern. Additionally, regionally different (e.g., OMI a little higher King Sejong station, but lower station TOC). Thus, it seems necessary consider difference better assessing spatiotemporal pattern
