In AIP Advances, Qing-Bin Lu, a scientist from the University of Waterloo in Ontario, Canada, reveals a large, all-season ozone hole in the lower stratosphere over the tropics comparable in depth to that of the well-known springtime Antarctic hole, but roughly seven times greater in area. His observed data agree well with the cosmic-ray-driven electron reaction (CRE) model and strongly indicate the identical physical mechanism working for both Antarctic and tropical ozone holes.

Spring 2020 arctic “ozone hole” likely caused by record-high north pacific sea surface temperatures
Unlike the Antarctic ozone hole that develops annually during austral spring (September, October, and November), Arctic ozone levels usually stay well above the ozone hole threshold.
