Answer 1

The thickness of the ozone in a column of air from the ground to the top of the atmosphere is measured in terms of Dobson units (DU). It is named in honour of British meteorologist G.M.B. Dobson, who invented the device Dobson Meter, and established a worldwide network of ozone monitoring stations, which continue to operate to this day.
