Which gas observes the sun's ultraviolet rays?

The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet (UV) radiation. It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. read more

Oxygen. The O2 absorb UV rays and split into [O] which later combine with another O2 to form O3(ozone gas). Then O3 split and recombine absorbing UV rays and releasing the energy as heat to the atmosphere. This is how oxygen protect Earth from UV rays. read more
