Fallout-Particle-Trajectory Computations and Fallout-Particle Arrival Time Calculations.

摘要

This report describes the Weather Service Nuclear Support Office (WSNSO) procedure for deriving estimates of fallout-particle arrival times along a fallout pattern. Analyses of meteorological data are discussed. The equations and calculations used in deriving particle-sedimentation velocities and times in layers are discussed. 17 refs., 21 figs., 6 tabs.
