Abstract: Previous whiteout work done by CRREL from 1954 to 1962 is outlined and field studies by CRREL in 1963, including instrumentation, seeding materials, and test procedures are discussed. The 1963 experiments were designed to test the feasibility of using recently developed rockets (cold-propellant and solid-fuel types), continue the investigation of tethered balloon techniques, and field test the organic compound phloroglucinol, which was recently found to be an effective ice-nucleating reagent in the laboratory. A ground-based system for fog dispersal is feasible. Of the many systems tested, the CRICKET is the most promising. It can be moved easily to any suitable area, penetrate fog or clouds to heights of about 4000 ft, and is less expensive to buy and operate. It was concluded that better tracking and observing techniques are needed to determine if the seeding is effective. Monitoring a test from the ground in a dense low fog is difficult because (1) observers easily get lost, and (2) variable air movements make uncertain the drift of the seeded area.
