The chemistry of ozone destruction involves very small quantities of stratospheric gases which change rapidly with altitude. UARS is able to determine the altitude variation of these gases by looking at the atmosphere edge on. This is called limb sounding. The Microwave Limb Sounder (MLS) measures microwave emission from ozone and chlorine monoxide, a major ozone destroying radical.
