Fig. 4: October partial column ozone (PCO) over four altitude and latitude ranges of interest derived from MLS observations for 2004–2022.

From: Potential drivers of the recent large Antarctic ozone holes

Fig. 4

Red line: PCO for the pressure levels of 5-50 hPa and averaged from 60∘S to 82∘S; Pink line: As red line, but now averaged from 75∘S to 82∘S; Dark blue line: PCO calculated for pressure levels 1–5 hPa and averaged from 60 ∘S to 82 ∘S; Light blue line: As dark blue line, but now averaged from 45∘S to 60∘S. The results from linear fits are shown in the legend, with errors quoted at 95% confidence interval. Here, T = years since 2004, and the percent change in PCO since 2004 is given after the Δ-symbol.
