POAM III  

Definition

  • The Polar Ozone and Aerosol Measurement III (POAM III) instrument was developed by the Naval Research Laboratory (NRL) to measure the vertical distribution of atmospheric ozone, water vapor, nitrogen dioxide, aerosol extinction, and temperature. Measurements are made using the solar occultation technique; the Sun is observed through the Earth's atmosphere as it rises and sets as viewed from the satellite. Solar extinction is measured in nine narrow band optical channels, covering the spectral range from 350 to 1030 nm POAM III is an improved version of POAM II. It has an improved electronic system that provides lower noise and more accurate measurements. The optical filters were manufactured with a better technology that yields higher transmission and greater ability to withstand the space environment. The wavelengths and bandwidths of the science channels differ slightly from those in POAM II. POAM III, like POAM II, was fabricated by ThermoTrex Corporation in San Diego, California.
