  • Total Ozone Mapping Spectrometer (TOMS) - provides global measurements of total column ozone on a daily basis
  • Dobson unit - (DU) - a measure of the thickness of the ozone layer.  Suppose all the ozone over a certain area of the earth is compressed down to 0oC and 1 atm of pressure.  If the thickness of the resulting slab is 3 mm, this is 300 DU.
