Optical/IR Characteristics of Alkali Halide Aerosol Clouds over the Ocean.
Artificial fogs grown on hygroscopic alkali halide (Salty Dog) nuclei were produced over the North Atlantic Ocean using 180 pound pyrotechnic generators deployed from the USNS LYNCH. Canopy Clouds were produced when heat from the burn carried the material aloft, if the relative wind at the ship was...

Artificial fogs grown on hygroscopic alkali halide (Salty Dog) nuclei were produced over the North Atlantic Ocean using 180 pound pyrotechnic generators deployed from the USNS LYNCH. Canopy Clouds were produced when heat from the burn carried the material aloft, if the relative wind at the ship was small during the burn. Surface clouds wee formed if the burn took place while the ship was in motion relative to the surrounding air. When the wind speed was less than the ship's speed, it was possible to re-enter the surface clouds and make measurements on the size distribution of the aerosol particles. Shipboard instrumentation measured the particle size distributions and light scattering characteristics of those clouds which the ship could enter. The agreement between measured extinction and that calculated form particle size was good. Only remote sensing could be used for canopy clouds, and sun photometer measurements of the light extinction by the canopy clouds were consistent with theoretical estimates of changing particle size distributions.
