Abstract : Launch plume visible and infrared imagery were accomplished during the launch of Titan IV Mission #K13 at Vandenberg Air Force Base on 20 December 1996. These data will be used to improve the accuracy of the Rocket Exhaust Effluent Diffusion Model (REEDM). The imagery from three sites measured a cloud stabilization height of 828 m AGL compared to a REEDM-predicted stabilization height at 753 m AGL. This height was reached in 4 to 7 min compared to a REEDM prediction of 3.67 min. The imagery-derived cloud trajectory was 296 deg compared to the 332 deg trajectory predicted by REEDM. Measurements of aerial and ground-level concentrations of hydrogen chloride (HCl) were not taken during this launch.
