Description
Summary:Phase I of Project Whiteout was conducted in North Greenland to determine the extent to which whiteouts could be modified. Phase II is a laboratory experiment to develop specialized whiteout-dissipation procedures. Findings indicate that a 'stationary' seeding technique may modify supercooled clouds and fogs in the -5C to 0C range and the use of low-density, high drag flakes or pellets of dry-ice may permit an ex tension of conventional aircraft seeding techniques to warmer temperatures. Several types of seeding vehicles were examined, including drone aircraft, mortar shells, rockets, and standard aircraft. A mechanism for the conversion of liquid CO sub 2 into dry-ice pellets was conceived for use in emergency-seeding aircraft devices.
