Tour of Ozone Hole

Major objective of this lecture is to present on Tour of Ozone Hole. Dramatic loss of ozone in the lower stratosphere over Antarctica was first noticed in the 1970s by a research group from the British Antarctic Survey (BAS) who were monitoring the atmosphere above Antarctica. Ozone forms a layer in the stratosphere, thinnest in the tropics (around the equator) and denser towards the poles measured in Dobson units (DU) ~260 DU near the tropics.
