A strong polar vortex supported the formation of a large and deep Antarctic ozone hole in September 2020 that should persist into November, NOAA and NASA scientists reported today.

Throughout the Antarctic winter, the researchers will collect air samples to help maintain long-term records of trace gases, aerosols, and solar radiation.
