Fogwash 1, An Experiment Using Helicopter Downwash

Abstract

The report documents Project Fogwash 1, an experimental program in which the technique of helicopter downwash for fog dissipation was used. Meteorological and microphysical data collected during the experiment are presented. Meteorological data indicated an improvement in visibility as a result of the downwash. There were indications in the microphysical data obtained that particulate number varies directly as relative humidity and inversely as temperature and that sulfate particles increase with increased relative humidity.
