NASA NTRS1992

Submillimeter-wavelength heterodyne spectroscopy and remote sensing of the upper atmosphere

Remote sensing by means of heterodyne spectroscopy at sub-mm wavelengths, which are rich in the spectral lines of atmospheric molecules, can furnish measurements for monitoring changes and studying processes in the earth's upper atmosphere. An experiment for this purpose, covering spectral bands near 63, 183, and 205 GHz, has become operational on the NASA Upper Atmosphere Research Satellite; an experiment whose spectral bands reach to 2.5 THz is under study for future earth observations.

NASA NTRS1991

Submillimeter heterodyne remote sensing of upper atmospheric gases

Technology now becoming available for submillimeter heterodyne remote sensing of upper atmospheric gases is discussed. The general features of microwave limb sounding are reviewed, and the UARS Microwave Limb Sounder, a NASA mission dedicated to the comprehensive and integrated study of earth's upper atmosphere, is briefly described. The EOS Microwave Limb Sounder is briefly examined, showing its expected measurement capability for various gases.

The microwave limb sounder (MLS) experiments for UARS and EOS

Microwave limb sounding can provide important measurements for understanding global change and processes in earth's stratosphere, mesosphere, and lower thermosphere. An experiment for this purpose operating at millimeter wavelengths is now ready for launch on the NASA Upper Atmosphere Research Satellite (UARS). An enhanced experiment at submillimeter wavelengths is also being studied for the future NASA Earth Observing System (EOS).
