Abstract:

The report describes lidar laser radar observations of the dust and steam clouds that resulted from the Pre-GONDOLA I series of four chemical explosions made near Fort Peck Reservoir, Montana, during October-November 1966. The neodymium lidar was well able to track the clouds even when they became too tenuous to be seen visually or photographed. Observational data were analyzed to obtain cloud dimension, height, volume, rate of growth, volume backscatter coefficient and relative density variations.
