The Operational Dissipation of Supercooled Fog
Author: Herbert S. Appleman

ISBN:
Category : Dry ice
Languages : en
Pages : 10
Book Description
In the winter of 1967-1968, the Air Weather Service (AWS) carried out its first operational weather-modification program at Elmendorf AFB. An AWS weather-reconnaissance aircraft (WC-130E) was used to seed supercooled fog with dry ice. A prescribed flight path was flown a specified distance upwind from the target area, and crushed dry ice disseminated at rates of 12.5 or 25 pounds per mile. It was found that a clearing generally occurred in 30 to 45 minutes. The only real failure occurred in a case that may have been an ice fog; in addition, proper positioning of the hole proved to be a major problem throughout the program. Despite these difficulties, an estimated 200 successful take-offs and landings were made using the artificially produced clearings. Supplemental tests were carried out using airborne liquid CO2 dispensers and silver iodide pyrotechnics.

Area-dosage Relationships and Time of Tracer Arrival in the Green Glow Program
Author: William P. Elliott
Publisher:
ISBN:
Category : Geomorphological tracers
Languages : en
Pages : 50
Book Description
An empirical relationship between the area in which a given dosage is equalled or exceeded and the value of the dosage itself are developed using Green Glow data. It is found that the logarithm of the area is nearly a linear function of the logarithm of the dosage divided by the source strength and multiplied by a representative wind speed. These results differ only slightly from similar results obtained from Prairie Grass data. Observations of the time of first arrival of the tracer near ground level at distances of 8 and 16 miles from the source indicate that the tracer material which first arrives has travelled with a wind speed greater than the surface wind (about 15 ft). It would be necessary to have wind speed measurements between 50 and 100 ft above ground in order to estimate the time of first arrival at these distances even though the source is no higher than 15 ft.
