The term "Ozone layer" despite its frequent use, is generally understood in a way that lends itself for a misunderstanding. The term suggests that, on a certain height in the atmosphere, there is a level of concentrated ozone that covers and protects overcasting the land like a sky as a cloud layer.

Ozone is a much diluted little gas in the air and, in addition, appearing from the ground to up beyond the stratosphere. The ozone layer is located in the stratosphere, about 15 to 50 km on the planet's surface. In addition, ozone is an unstable compound of three oxygen atoms, which acts as a powerful solar filter preventing the passage of a small part of the ultraviolet rays (UV) called B extending from the 280 to the 320 nanometers (nm).

UV-B radiation may cause damage in living beings, depending on its intensity and exposure time.  These damages can range from skin irritation to conjunctivitis and deterioration of the immune system, affecting the growing of plants and damaging the phytoplankton, with subsequent consequences changing the normal and natural way of development of the marine fauna.

Ozone is a very low-slung gas that if we have to separate it from the rest of the air and have to bring it to the ground-level we would only obtain three mm of thickness.

 Ozone is everywhere and at any height. Even in the stratospheric levels in maximum relative concentration it has less components of the mixture of gases compounding the air. Its height in the air gets to represent only the 0.001% of the total volume of it.
