Today we learn about protecting ozone layer, start from how the ozone is produces, why there is a depletion, the cycle of ozone, the change in concentration, and many more.
As we know the ozone is depleting due to many production of greenhouse gases. The ozone concentration is also change overtime.

Today we discussed about the Ozone Layer in our class, CM8001.
We learnt about the importance of the Ozone Layer; it absorbs some UV radiation,
learnt where the Ozone Layer is; the Stratosphere,
learnt that the chlorine atoms in CFCs act as the catalyst that decompose the Ozone Layer,
learnt that UV-A is the region of the ultraviolet spectrum least absorbed by the atmosphere (honestly I didn’t even know there was more than 1 region),
but one of the most important thing we learnt today is that the Ozone Layer is not equal throughout.
Some parts of the Ozone Layer contains more Ozone than others, and with no prior knowledge in this subject/topic might not know this because of the name “Ozone Layer” which might be misleading.
I give today’s lesson a 10/10 for information and knowledge acquired.

The new thing I learnt today is The Chapman Cycle.
O2 -> 2O (242nm)
2O + 2O2 -> 2O3 (fast)
2O3 -> 2O +2 O2 (320nm)
3 X 10^8 tons of O3 at steady state
Dynamic balance of Ozone in the Stratosphere.
We learnt more about the ozone layer in today’s class. Stratospheric Ozone serves as a protecting layer by absorbing the UV rays. However, as the years go by, it has been observed that the ozone layer is depleting and this can be further explained by various chemical reactions.
