Available in PDF, EPUB and Kindle. Book excerpt: The technique of upper atmosphere measurements by analyzing the chemiluminescence of nitric oxide trails deposited by rockets was investigated using wind tunnel simulation. The nitric oxide was released from a model into the low density tunnel flow which had been partially dissociated upstream of the plenum chamber by microwave discharge. The radiant power produced was measured separately by photographic and photoelectric techniques under controlled nitric oxide and atomic oxygen concentration flow rates. The tests were conducted at Mach number 3.4 and at freestream pressures between 1 and 10 microns Hg. The geometric shape of the radiating mixing layer contained between two shockwaves was observed and described in terms of the flow rates. The chemiluminescent NO + O to NO2 + photon reaction rate measured by two independent techniques was found to be k = 3 (plus or minus 2) x 10 to the -12th power cu cm/molecules/seconds. Scaling laws were developed to relate the radiant power to the concentration flow rates. These scaling laws were then used to determine the absolute oxygen concentrations in the upper atmosphere from previously conducted flight experiments. Excellent agreement was obtained between the densities obtained by the nitric oxide release technique and mass spectrometer measurements. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Nitric oxide was injected into a supersonic stream of air containing atomic oxygen in a low density wind tunnel. A photon emission rate was measured in the reaction zone of 3 x 10 to the -12th power cc/sec which is higher by 4-5 orders of magnitude than observed in "ordinary" laboratory flow tubes. This confirmed observations during upper atmosphere releases of nitric oxide.

Available in PDF, EPUB and Kindle. Book excerpt: Freeze dried polystyrene aerogels or fluffs, when reacted with gaseous atoms, yield stable, free radical products at concentration levels dependent upon the concentration of the reacting atoms. These reactions, as applied to oxygen and nitrogen atoms, were investigated to determine the feasibility of their use as a means of atom sampling in the upper atmosphere. Electron paramagnetic resonance spectroscopy was used for qualitative and quantitative product analysis. The results of the preliminary investigation revealed that about 1% of the atoms passing through the fluff were captured. Measurements of lifetimes showed that about 1000 minutes were required for decay to half a starting product concentration. Such reaction efficiencies and product lifetimes are sufficient for upper atmosphere sampling and remote measurement. Oxygen atoms are in excess over nitrogen by one to three orders of magnitude. The reaction rates of both atom species with fluff are similar resulting in negligibly small interference from N atoms during oxygen atom measurements. (Author).

This book was released on 1965 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cumulus cloud events of the Florida peninsula that were observed during a 19-day period of photoreconnaissance in August and September 1957 are described and illustrated. The associated meteorological and rainfall events are also described and the intercorrelations among the various observations are pointed out. The study findings revealed that the principal factors governing the cloud and rainfall situations of the different days were (1) the low-level advection of water vapor into the peninsula from the oceanic surroundings, (2) the wind transport, into the heated peninsula from the oceans during the daytime, of pre -existing cumulus populations containing appreciable liquid water, (3) the low-level convergence, and associated updraft motion, engendered by the synoptic situation and the peninsula sea breezes, and (4) the precipitable water content of the lower Florida air mass.
