Influence of the Ozone Layer in the Atmosphere

Vesselina Ilieva, Silvia Kotseva


The atmospheric ozone (O3) is a small ingredient of the air with strong influence on the environment which can be positive or negative. One distinguishes stratospheric ozone and tropospheric ozone. The first one absorbs considerable amount of the strong ultraviolet (UV) sun radiation, thus preserving the life on the planet Earth. It also regulates the thermal regime of the lower stratosphere.

This article is devoted to the description and explanation of various problems related to the atmospheric ozone: photochemistry, depletion and formation of the so called “ozone hole”, biological influence of O3 on the people (skin and ayes diseases)) etc.

The history of the O3-investigations and the O3-monitoring as a global problem is also discussed.
