Question:
I am trying to find out if there is a partial hole in the Ozone Layer in the South American Region. Would you happen to know if there is, and what geographical area is it situated over.



Replies:
Fraser,

The very southern tip of South America is sometimes affected by some decrease in ozone from the dilution over Antarctica, however, it is quite small. The greater problem occurs during the breakup of the ozone "hole" in late Spring. Blobs of ozone depleted air float over much of southern South America, posing a significant skin cancer hazard to those who live there.

Take a look at more information and lots of neat ozone "hole" graphics at www.atm.ch.cam.ac.uk/tour/index.html
