Abstract : In the second year of its full-scale weather-modification program, the Air Weather Service carried out four supercooled-fog dissipation projects, two airborne and two ground-based. Airborne techniques using crushed dry ice and silver iodide fuses can now be considered fully operational, although testing will continue in order to optimize the equipment and techniques. The ground-based liquid-propane technique has reached a point to justify an operational test program using a network of fixed propane dispensers. The results of the ground-based warm-fog dissipation test, using sized sodium nitrate, indicated that this approach offers a possible solution to the problem.
