Abstract : Launch plume visible and infrared imagery were accomplished during the launch of Titan IV Mission #K24 at Cape Canaveral Air Station on 23 February 1997. These data will be used to improve the accuracy of the Rocket Exhaust Effluent Diffusion Model (REEDM). The imagery from four sites measured a cloud stabilization height of 803 m AGL compared to a REEDM-predicted stabilization height at 920 m AGL. This height was reached in 2.75 to 3.75 min compared to a REEDM prediction of 3.89 min. The imagery-derived cloud trajectory was 76 deg compared to the 300 deg trajectory predicted by REEDM. Measurements of aerial and ground-level concentrations of hydrogen chloride (HCl) were not taken during this launch.
