<li>Ozone thickness is measured in Dobson Units (DU).</li>
<li>One Dobson Unit represents a layer of ozone that is 0.01 millimeters thick under standard temperature and pressure.</li>
<li>Average ozone layer thickness ranges from 300 to 500 Dobson Units.</li>
<li>Thickness varies based on geographic location and time of year.</li>
<li>Higher values are generally found at mid-latitudes.</li>
<li>Lower values are typically found near the equator and poles.</li>
<li>The Dobson unit is named after Gordon Dobson who built the first instrument to measure total ozone from the ground.</li>
