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.
