Now, for example, in our structure with ozone it's between all three atoms.

Ozone in the stratosphere is important because it absorbs some of the Sun' s dangerous ultraviolet radiation.

These wonders can be observed only from space, because ozone and water in the Earth' s atmosphere absorb light at those wavelengths.

But it can be a vacation for the lungs too, as it has some of the nation' s lowest levels of both ozone and particulates.

It is not possible to tell from this view exactly what pollutants made up the haze on February 20, but it probably contains mostly soot or black carbon and possibly some ground-level ozone.
