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. WebThe stratospheric ozone layer protects life on Earth by absorbing ultraviolet light, which damages DNA in plants and animals (including humans) and leads to sunburns and skin cancer.
