Abstract:

Results of launch cloud imagery and ground-level HCl measurements performed at Cape Canaveral Air Station CCAS during the launch of a Titan IV vehicle from Complex 40 on 22 December 1994 are presented. Meteorological data measured at numerous CCAS locations prior to launch and during dispersion of the launch cloud are also presented. Such data will be used to determine how accurately atmospheric dispersion models such as the Rocket Exhaust Effluent Diffusion Model REEDM can predict toxic hazard corridors during launches of Titan and other vehicles at the ranges. A wind from the northwest rapidly blew the launch cloud out to sea. This wind prevented the deployment of sensors for far-field 8-40 mi., downwind HCl monitoring. HCl detectors and dosimeters were thus deployed at selected near-field locations. The responses obtained with these sensors are consistent with the launch clouds trajectory. REEDM predicted a maximum ground-level HCl concentration 10.5 mi. downwind from Complex 40. No HCl sensors were present at far-field, offshore locations to determine the accuracy of this prediction. Future HCl monitoring efforts will emphasize far-field measurements. AN
