The Improved Stratospheric and Mesospheric Sounder (ISAMS) measured vertical profiles of temperature and a number of atmospheric constituents. An instrument on board UARS (Upper Atmosphere Research Satellite) measured global stratospheric and mesospheric temperature, CO, H2O, CH4, O3, HNO3, N2O5, NO2, N2O and aerosol extinction. Gridded, global measurements between 80S and 80N, October 1991 - July 1992. This data is the raw level 0 and engineering data used in calibration. The data is as found on the mission ground segment support computer.

Abstract This computation involved: DETAILS NEEDED - COMPUTATION CREATED FOR SATELLITE COMPOSITE. deployed on Upper Air Research Satellite (UARS). The satellite was launched in 1991 by the Space Shuttle Discovery. It is 35 feet long, 15 feet in diameter, weighs 13,000 pounds, and carries 10 instruments. UARS orbits at an altitude of 375 miles with an orbital inclination of 57 degrees. Designed to operate for three years, UARS was finally decommissioned in December 2005. UARS measures ozone and chemical compounds found in the ozone layer which affect ozone chemistry and processes. UARS also measures winds and temperatures in the stratosphere as well as the energy input from the Sun. Together, these help define the role of the upper atmosphere in climate and climate variability.
