Ozone layer - Wikipedia
WebOzone layer thickness is measured in Dobson units. By dividing the Dobson unit reading by 100, you get the thickness in millimetres of a layer of ozone gas at ground level (the average amount of ozone in the atmosphere is roughly 300 Dobson Units, equivalent to a layer 3mm thick). The higher the number, the thicker the ozone layer. Tables WebPrecursors used were or and together with ozone.
