Ozone Hole

APRIL 2023

FIGURE S8.  Daily time series showing the size of the ozone hole (denoted by total ozone <220 DU), the size of SH polar vortex (representing the area enclosed by the 32 PVU contour on the 450K isentropic surface), and the area coverage of temperatures < -78C on the 450K isentropic surface.
