The strong Antarctic vortex plays a crucial role in forming an expansive region with significant stratospheric ozone depletion during austral spring, commonly referred to as the “ozone hole”. This study examines daily column behavior this phenomenon using ERA5 reanalysis data and ground-based observations from 10 stations collected between September December 2008 2022. A preliminary analysis of these datasets revealed smoothly varying patterns quasi-uniform gradients distribution within hole. observation led hypothesis that average columns over zones, defined concentric areas around South Pole, can be estimated mean values measurements derived station observations. aims evaluate validity hypothesis. results indicate levels calculated at two stations—Belgrano Dome Concordia, or Belgrano Arrival Heights—provide reliable approximation zone spanning 70°S 90°S. Including additional extended northward 58°S. error was range 5% 7% 1σ 6% 8% 10th–90th percentile levels. Furthermore, geographical enabled schematic reconstruction hole’s position shape. On other hand, high frequency contributed studying hole variability both inner area edges on hourly time scale. These findings have practical implications for near-real-time monitoring development, along satellite observations, considering source information about layer Pole region. also suggest possible ground analyses pre-satellite-era behavior. Additionally, found degree consistency corresponding data, further supporting reliability
