Good Up High, Bad Nearby!
Diffuse layer containing ozone (O3) molecules
Reacts with UVB light from the sun
Reduces skin cancer where layer is thick
In the mid-stratosphere over the tropics ozone (O3) is created:
1. Oxygen is split by UV light
and is decomposed,
ex: freonCl + O3ClO + O2
ClO + O Cl + O2
net: O + O3 2O2
