The thickness of the ozone layer is measured in Dobson units. Divide the reading of stratospheric ozone in Dobson Units by 100 and you have the thickness in millimetres of a layer of pure ozone gas at ground level formed from all the ozone in the ...
ozoneOzone measurements are given in Dobson units and are integers with 3 significant figures. A Dobson Unit represents the physical thickness of the ozone layer if it were brought to the earth's surface.
For example, 300 Dobson units of ozone brought down to the surface of the Earth at 0° C would occupy a layer only 0.3 cm thick in a column.
Column Ozone: The total amount of ozone present in a column of the Earth's atmosphere from the surface to the top of the atmosphere. It includes both surface level ozone and ozone found in the ozone layer. Measurement is either in Dobson Units ...
