  The Ozone Layer Protects Us Against Harmful Solar Ultraviolet Radiation
How the ozone layer protects against harmful ultraviolet radiation from the sunOzone in the stratosphere absorbs some of the Sun’s biologically harmful ultraviolet radiation. Most of the short-wave radiation (so-called UV-B) is absorbed by the ozone layer, whereas long-wave UV (so-called UV-A) passes through the ozone layer and reaches the ground.

 

  UV index
Global Solar UV Index The intensity of UV radiation can be expressed by the UV index. WMO has issued, in collaboration with WHO and other organisations, a guide on how to report solar UV radiation to the public. Awareness on how to behave in the sun is important for curbing the rapid increase in skin cancer oberved in many populations. Click on the image to download the report.
