The handbook sets forth the procedures and techniques for gathering and evaluating the meteorological data necessary for predicting the focus of air blast from surface or near surface explosions, and it describes simple devices to speed the calculations. All the graphs necessary for the evaluation are gathered for easy reference. Eighty-seven sets of vertical velocity gradients and the resulting sound ray paths are assembled for rapid determination of focal distance. These should cover most of the conditions to be expected throughout the continental United States.
