🛡️ Ozone Layer Lab: Chapman Cycle, Chlorine Catalysis, the Ozone Hole and the UV Index

Watch the stratospheric ozone layer form from the Chapman cycle, then add chlorine from CFCs: a 1-D photochemical model gives the profile, the Dobson column, the polar ozone hole after weeks of ClO chemistry and the resulting UV index, with ultraviolet rays that are absorbed layer by layer.
