Abstract : Launch plume imagery, airborne and ground-level HCl measurement results, and meteorological data measured during the launch of a Titan IV vehicle at Vandenberg Air Force Base on 5 December 1995 (mission K-15) are presented. These data is used to determine the accuracy of the Rocket Exhaust Effluent Diffusion Model (REEDM). The imagery showed the separation into ground cloud and launch column segments, with the ground cloud stabilization height occurring 28% higher than predicted by REEDM. It also moved in a direction 24 deg more clockwise than predicted by REEDM, and 21% faster, but in good agreement with that calculated for the rawinsonde T-15 minute data. Of 34 dosimeters placed along the projected plume path, all but three provided usable data, ranging from 13 to 340 ppm min dosages. Aircraft data during cloud fly throughs were obtained using both the Geomet and Spectral Science instruments.
