Atmospheric environment for Space Shuttle Atlantis (STS-43) launch

A summary of selected atmospheric conditions observed near Space Shuttle Atlantis (STS-43) launch time on August 2, 1991, at Kennedy Space Center, Florida is presented. Values of ambient pressure, temperature, moisture, ground winds, visual observations (cloud), and winds aloft are included. The sequence of prelaunch Jimsphere-measured vertical wind profiles is given. The final atmospheric profile, which consists of wind and thermodynamic parameters versus altitude, for STS-43 vehicle ascent was constructed. The STS-43 ascent atmospheric data profile was constructed by Marshall Space Flight Center's Earth Science and Applications Division to provide an internally consisted data set for use in postflight performance assessments and represents the best estimate of the launch environment to the 400,000-ft altitude that was traversed by the STS-43 vehicle.
