High Plains Cooperative Program Cloud Survey and Seeding Research Aircraft and Associated Data Processing.

摘要

An instrumented aircraft capable of seeding clouds with silver iodide and dry ice was operated as part of the Hiplex Program of the USBR DAWRM at Miles City,Montana during June and July, 1976. Seeding systems included AgI-NH4I acetone generators,wing and fuselage mounted racks for ejectable and burn-in-place AgI pyrotechnic flares. Dry ice (CO2) in the form of small pellets were also released from the aircraft. Variable concentration and delivery methods were used to evaluate seeding materials and dispersion techniques. On on-board data system recorded cloud parameters during survey and seeding experiments. All flight observations of atmospheric data i.e. air temperature,dew point,pressure,indicated air speed,liquid water content,rate of climb were observed every 8.5sec and recorded on computer compatible magnetic tape. Seeding locations and pertinent data concerning seeding are given.
