Paper Abstract

The Cryogenic Limb Array Etalon Spectrometer (CLAES) is one of a complement of instruments on the NASA Upper Atmosphere Research Satellite (UARS) which will study atomospheric photochemistry, energy input, and dynamics following a 1991 launch. CLAES will measure stratospheric altitude profiles of temperature, pressure, 03, H2O, CH4, N20, NO, NO2, N205, HNO3, C1ONO2, HC1, CFC-11, and CFC-12. These data will be obtained typically between 10 and 60 km, with 2.5-km vertical resolution and 500-km horizontal grid size. Coverage will be obtained between latitudes 80° north and south, thereby providing substantial coverage of the Antarctic spring polar ozone-hole region. The experiment will have a minimum useful on-orbit operating lifetime of 15 months, as dictated by the lifetime of the stored solid-neon/solid-CO2 cryogen. CLAES derives the listed geophysical parameters from measurement of earth-limb spectral emissions between 3.5 and 13 μm. Brief discussions of the measurement concept, instrument design, and performance are presented, followed by a more detailed discussion of scientific capabilities and measurement modes.
