Ground Cloud Dispersion Measurements during the Titan IV Mission Number K19 (10 July 1995) at Cape Canaveral Air Station.
Abstract
Launch plume imagery and ground-level HCI measurement results and meteorological data determined during the launch of a Titan IV vehicle at Cape Canaveral Air Station (CCAS) on 10 July 1995 (mission #K19) are presented. These data will be used to determine the accuracy of the Rocket Exhaust Effluent Diffusion Model (REEDM). The imagery data, recorded from three camera sites, show that the ground cloud blew out to sea with a northeasterly trajectory (2220) consistent with T-I hour rawinsonde data (215-218%). For this 8:38 EDT (12:38 Zulu time) morning launch, visible and infrared imagers viewed the launch plume against the rising sun. The infrared imagery results were found to be superior to the visible imagery results during most of the #K19 plume tracking since parts of the visible imagery were saturated with scattered sunlight. The imagery data show that the stabilization height of the ground cloud (1850 m) was twice that predicted by REEDM, as was found for the Titan IV #K23 launch. Ground-level HCI measurements made by dosimeters placed on the pad's lightning towers and perimeter fence, as well as along Phillips Parkway, also show that the ground-cloud moved to the northeast.
