Ozone depletion

The ozone layer is a layer in Earth's climate which contains generally high convergences of ozone (O3). This layer assimilates 93-99% of the sun's high recurrence bright light, which is possibly harming to life on earth. Over 91% of the ozone in Earth's climate is available here. It is for the most part situated in the lower segment of the stratosphere from around 10 km to 50 km above Earth; however the thickness changes occasionally and geographically. The ozone layer was found in 1913 by the French physicists Charles Fabry and Henri Buisson. Its properties were investigated in detail by the British meteorologist G. M. B. Dobson, who built up a basic spectrophotometer (the Dobson meter) that could be utilized to quantify stratospheric ozone starting from the earliest stage. Somewhere around 1928 and 1958 Dobson built up an overall system of ozone checking stations which keeps on working today. The "Dobson unit", a helpful measure of the aggregate sum of ozone in a segment overhead, is named in his respect.
