Operation GREENHOUSE. Scientific Director's Report of Atomic Weapon Tests at Eniwetok, 1951. Annex 1.3. Thermal Radiation Measurements. Part 1. Atmospheric Transmission. Part 2. Total Thermal Radiation. Part 3. Radiant Power as a Function of Time--Photoelectric Measurements. Appendix A and Appendix B
Abstract
Atmospheric transmission measurements were most important to the thermal program since they gave the information which was necessary to compute and cancel out the effects of intervening air paths on measurements of total thermal energy, radiant energy, radiant power with respect to time, and spectral emission of the bombs. The brightness temperature of each of the Operation Greenhouse firebals was measured in two wavelength regions as a function of time. The measurements were made with high-speed filtered photoelectric systems located at Parry Island. The Teller Light phenomena is also covered. The Thermal Radiation Project included specific objectives of recording the spectra of the release of visible and ultraviolet radiation by an exploding nuclear weapon in three stages: Teller Light, first maximum, and second maximum.
