Note that the ozone hole is a natural. repeating occurrence, including healing shut again. The hole is not really a hole at all, but a thinning of the Ozone layer due to a lack of sun hitting that area. Without sunlight, ozone naturally reverts into O2, a more stable oxygen form. There is no actual hole, merely a thinner layer, with about 1/3 or so the summertime level of ozone.
Sightings are taken across straight line paths, and there is no significant absorption of specific light wavelengths that ozone would absorb if it were present. That absorption would be proportional to the amount of ozone over the entire path. The absorption of those specific wavelengths are a couple of orders of magnitude lower during the winter at the pole with the ozone hole, than at other times of the year there.
Yes, there is an ozone hole over Antarctica when it is winter there, and a smaller hole appears over the Arctic when it is winter there. The one over Antarctica is larger than the one over the Arctic, due to the actions of Nature.
What is more, since that pole gets no UV-C to make ozone, and ozone decays with time (just a few days, usually less), there *must* be a hole. The only question is, how big is the hole... that is where the science and "Man-caused-or-not" effects come in.
CFCs have been observed in trace quantities in the "holes". CFCs are known to destroy ozone. The question science experts have and do not know the answer to is how much (if at all) this chemical is affecting the size of the thinning area. (Water vapor is already well known to do the same and is the known primary driver).
What else can I help you with?
What months does the ozone hole occur in antarctica?
The ozone hole in Antarctica typically occurs from September to November, with the largest depletion usually observed in October. This is during the Southern Hemisphere's spring when unique atmospheric conditions contribute to the formation of the ozone hole.
How did you know that the ozone layer had a hole?
The ozone layer has a hole.It was proven by scientists.
How many holes is there in the ozone layer?
The ozone layer has a hole over Antarctica known as the ozone hole. This hole varies in size throughout the year but reaches its maximum size in September. The hole is caused by the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances into the atmosphere.
Why is there a ozone hole?
Ozone hole is the thinning of ozone layer. It is due to ODS.
How useful was the Antarctic ozone hole?
The Antarctic ozone hole is not useful. It was harmful.

How they descoverd ozone hole?
Ozone hole was discovered by Joseph Farman. He discovered the ozone hole over Antarctica.
In 1985 a hole in the ...was discovered over Antarctica.?
yes, and it was the "antarctic ozone hole"ozone layer
What country is in the Antarctic region where the ozone hole exists?
The hole in the Ozone Layer over Antarctica has affected countries farther north, such as Chile and Argentina. These countries are not in the 'Antarctic Region', but are affected nonetheless.
What gases contribute to the hole in the ozone?
CFC's contribute to ozone hole. They react with the ozone.
