Abstract:

The problem, of determining the optimum height of release to obtain maximum area enclo ed by concentration isopleths for an aerosol munition, is discussed. A procedure is given for obtaining dimensionless crosswind depositions. The resulting curves are applicable for many sets of meteorological and physical conditions. When parameters characterizing these conditions have been estimated they re easiy put into the dimensionless solution to obtain real deposition. The dfference between aerosol ground and depositions resulting from many trias and ground depo ition from a single trial is explained. A method for obtaining horizontal and vertical flux of particles at height z, from a line sourc , un er a iabatic conditions is described. An approximation to the variance of coverage is derived when square exponential dosage fields are no mally distributed ov r a l rge target. Expressions for moments of total dosage were also obtained.
