Abstract:
The High-Resolution Doppler Imager (HRDI) on the Upper Atmosphere Research Satellite (UARS) is a triple-etalon Fabry-Perot interferometer designed to measure winds in the stratosphere, mesosphere, and lower thermosphere. Winds are determined by measuring the Doppler shifts of rotational lines of the o2 atmospheric band, which are observed in emission in the mesosphere and lower thermosphere and in absorption in the stratosphere. The interferometer has high resolution (0.05 cm-1), good offband rejection and excellent stability. This paper provides details of the design and capabilities of the HRDI instrument.
