The Polar Ozone and Aerosol Measurement (POAM) III instrument measures the vertical distribution of atmospheric ozone, water vapor, nitrogen dioxide, and aerosol extinction in the polar stratosphere and upper troposphere. The instrument was developed by the Naval Research Laboratory (NRL). POAM III was launched aboard the French SPOT 4 satellite in March 1998 into a Sun synchronous polar orbit.
