Description
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.
