| 内容記述 | The NASA Ames Airborne Autotracking Sunphotometer was used to obtain correlative optical depth measurements in conjunction with LITE (Lidar-In-Space Technology Experiment) measurements during STS-64 Orbits 35, 66, and 82, The sunphotometer was operated on, board the NASA C-130 and obtained data in Canada a few hours prior to the shuttle overpass during Orbit 35. Because of the approximate two-hour slip in STS-64 launch time, all overpasses in Canada after Orbit 35 occurred after local sunset. Therefore, immediately following the Orbit 35 C-130 flight, the sunphotometer was removed from the C-130 and transported via commercial carrier to Southern California, where ground-based measurements were taken prior to and during the shuttle overflights of Orbits 66 and 82. Vertical profiles of optical depth spectra, as well as ground-based spectra, are shown. The spectra derived from measurements acquired during Orbits 66 and 82 are compared with analogous spectra derived from solar radiometer measurements obtained by the University of Arizona at various Southern California sites. Both data sets are available for comparison to nearby LITE measurements and for calculation of backscatter-to-extinction ratios, derivation of aerosol size distributions, and use in transmission-correction of LITE signal profiles. |
