Question

In which of the following units is thickness of ozone layer measured?

• A. Dobson
• B. Joule
• C. Newton
• D. Decibel

Answer 1

The Correct Option is A

The thickness of the ozone layer is measured in Dobson units (DU). This unit quantifies the total amount of ozone in a column of the atmosphere and is named after G.M.B. Dobson, a researcher who extensively studied atmospheric ozone.

Answer 2

The thickness of the ozone layer is typically measured in Dobson units (DU). A Dobson unit is defined as the thickness of the ozone layer if it were compressed to standard temperature and pressure (STP), and is used to describe the concentration of ozone in the atmosphere.

• 1 Dobson unit (DU) corresponds to 0.01 millimeters of ozone at STP.
• The average ozone concentration in the ozone layer is about 300 DU, which corresponds to a thickness of about 3 millimeters if the ozone were compressed to the ground level.
