Thermal Flux and Albedo Measurements from Aircraft
Abstract
The primary objective was to obtain and evaluate experimental data of the basic thermal phenomena associated with the nuclear and thermonuclear explosions detonated between 5 May and 22 July 1956 at the Pacific Proving Grounds (PPG). These data were to be obtained from airborne instrumentation. The phenomena of interest were those of significance in the prediction of the thermal radiant exposure and irradiance at a point in space as a result of a nuclear explosion. The phenomena included: (1) fireball geometry, including size, shape, and rate of rise; (2) fireball characteristics as a thermal-energy source, including black-body quality, emissivity, and color temperature; (3) albedo effects of the earth's surface and of clouds; (4) effects of shadowing of the earth's reflecting surface (decrease in effective albedo at smaller angles of incidence because of surface roughness) and the obscuration by the fireball.
