BREWER Mklll Brewer Mklll Spectrophotometer FOR THE HIGHEST ACCURACY OBSERVATIONS OF UV AND OZONE Automatic total column Ozone and Sulphur Dioxide observations Reference quality spectral Ultraviolet radiation measurements

Introduction A major concern in many parts of the world is the amount of harmful ultraviolet radiation from the sun and sky that people are exposed to. ‘Holes in the Ozone layer’ are areas of stratospheric Ozone depletion and are not conned to the North and South Poles. They are indicators of the general health of the atmosphere, and a reduction in Ozone means that more harmful UV reaches the ground. Many Brewers are now purchased for research into the eects of Ultraviolet (UV) radiation from the sun and sky. The UV region covers the wavelength ranges 100-280 nm (UVC), 280-315 nm (UVB) and 315-400...

Brewers Around the World There are over 200 Brewers, in more than 40 countries around the World, from the tropics to the Arctic and Antarctic, most of these are shown on he map above. About 80 Brewer stations report Ozone and UV measurements to the World Ozone & Ultraviolet Data Centre (WOUDC). An UV-B stability kit external UV calibration lamp kit recommended for regular checks of the stability of the UV sensitivity (not required for Ozone and Sulphur Dioxide measurements. Brewer Accessories An insulated Cold Cover extends operation from -20 °C down to -50 °C, required for arctic and polar conditions...
