Reaction to the announcement of the observation of a large ozone hole over the tropics

A publication in the journal AIP Advances reports the detection over the tropics of a large ozone hole, defined as an area where more than 25% of the usual ozone has been lost. The hole would be comparable in depth to the well-known hole over Antarctica, but would cover an area seven times larger.

In my opinion the article lacks the scientific rigour necessary to be a reliable contribution. It contains a lot of reasoning with serious errors and unsubstantiated assertions, contradicting previous results that are substantiated. Ozone depletion in the tropics is nothing new and is mainly due to the acceleration of the Brewer-Dobson circulation. Finally, the journal in which it is published has a very low impact factor.
