Abstract:

Preliminary data on Phases 4 and 5 of Crowflight are given. The recalibrated U-2 duct curves are given. Tritium and Carbon-14 concentrations in New Jersey rain and air samples during 1959 and 1960 respectively are reported. The manner of mixing and transfer of Strontium-90 in the stratosphere is described. The seasonal increase in mixing from the tropical to polar regions is noted. Tungsten-185 distributions are discussed. Measurements of Rhodium-102 indicate that TeakAND Orange debris has entered the lower stratosphere. A mean residence time of less than 10 years for this debris is suggested. Concentrations of Beryllium-7, a cosmic-ray product, are reported. Strontium-89 and Cerium-144 data is discussed in the light of the HASP mixing model. The size distribution and composition of stratospheric particles collected on electron microscope probes exposed in the stratosphere is described. Particles in the size range 0.1 to 1.5 microns appear to be composed of ammonium persulphate. A stratospheric inventory of 5.7 x 10 to the 7th power Kg of SO4 is deduced. Author
