Abstract: The analysis of CIRRIS 1A (Cryogenic InfraRed Radiance Instrumentation for Shuttle) interferometric and radiometric data obtained during the flight of STS-39 (28 Apr - 6 May 1991) reveals the presence of IR emission in the 400 - 900 cm$+$MIN@1$/ (11 - 25 $mu@m) region not attributable to atmospheric emission. In this paper, data are shown which identify the signal as near- field water vapor present during all CIRRIS 1A observations. Variability of the near-field water vapor emissions is characterized and compared to mass spectrometer data also obtained on STS-39 (QINMS). Further investigation indicates that the water is excited to extremely high effective temperatures, possibly in excess of 9000 K. The data presented support the theory that water outgassed from the shuttle tiles is highly excited by collisions with atmospheric O, classifying is as a type of shuttle-induced glow never before measured in the LWIR.!15
