UK Stratospheric Ozone Measurements

General
Information

Introduction

Stratospheric ozone is a naturally-occurring gas that filters the sun's ultraviolet (UV) radiation. A diminished ozone layer allows more Radiation to reach the Earth's surface. Total ozone levels are at their annual peak in the late winter and early spring. However it is also at this time when man-made substances can lead to enhanced ozone depletion in the stratosphere. It is difficult to quantify these losses over the UK precisely since levels vary naturally by large amounts. The hole in the ozone layer has been a cause for concern for a number of years. UK ozone levels are recorded regularly to assess the changing state of the ozone layer and help us to understand the effects of different ozone levels on the ground.
