Several units of measurement are commonly applied to ozone: ppm - parts per million, usually parts per million volume (ppmV), detailing the number of molecules of ozone per million molecules of "air". Dobson Units (DU) - The number of ozone atoms in a column of atmosphere with a width and depth of a centimeter2 or meter2, and the entire height of the atmosphere from Earth's surface to the Sun (or the satellite measuring it). %wt or %vol - for a given amount of gas, how much of its mass (%wt) or volume (%vol) is just ozone. (Common for ozone generators.) mass/unit volume, pascals (partial pressure), and I won't atempt to chew up these definitions...

∙ 11y agoScientists measure the amount of ozone gas in a column of air. To measure this, they use Dobson units (DU). Dobson was one of the first scientists to research ozone.
One Dobson unit indicates 0.01 millimeter thickness of ozone gas in a column.
