Description
For aircraft operating in high latitude regions, communications using geostationary satellite relay may at times be affected by a phenomenon known as polar cap absorption (PCA). PCA is caused by charged particles, mainly protons, precipitating into the polar cap regions. The resultant increase of electron density in the lower ionosphere where the collision frequency is high, is responsible for the attenuation of signals passing through the region.In...

This report gives an account of the High Altitude Nuclear Detection Studies (HANDS) conducted at the Boulder Laboratories of the National Bureau of Standards and later of the Environmental Sciences Services Administration (ESSA) from approximately 1963 to 1968. This project represented a pioneer effort in the acquisition and processing of digital data from different disciplines of geophysics. It was one of the first in which an on-line computer formed...

Description
Reliable mapping of quasi-static total magnetic field changes to 0.1 gamma between stations separated by 1/2 km can be accomplished by use of a special paired rubidium magnetometer technique. This report discusses the limitations on profiling accuracy imposed by the intrinsic reproducibility of a rubidium horizontal gradiometer. It then describes a pier- differencing method of traversing which has been used to overcome this insufficiency and which...

Description
The instrumentation of small sounding rockets for scientific experiments in the region from 50 km to approximately 110 km is described. These particular rockets were developed to measure the diurnal variations of proton spectra and electron densities during solar proton events. Seven rockets were flown with each carrying a three-channel proton spectrometer and a three-frequency Faraday rotation experiment. The proton spectrometer and Faraday rotation...

Description
The response of a spherical particle to an accelerating environment is investigated. When the Reynolds numbers associated with such accelerations are small, the particle is in Stokes' regime and the linear equations governing its motion can be solved analytically. Outside Stokes' regime, which is the general case for spheres comparable in size to precipitation particles, the equations are nonlinear and must be solved numerically.The numerical solution...

O₂, N₂, and O number density profiles have been constructed in the 80-120 km region compatible with the U. S. Standard Atmosphere, 1962, and the U. S. Standard Atmosphere Supplements, 1966. Profiles have been constructed at 15, 30, 45, and 60°N, for winter, summer, and spring/fall.

Description
This report describes data acquisition and reduction methods that were used in investigations of large-amplitude, high-wave number, total magnetic field variations over exposed, basic volcanic rocks. The continuous profiling and discrete-station field operations procedures are detailed. A double-orthogonal-array mapping technique which eliminates mapping bias and allows full use of a folded (sin x)/x interpolator is also described. Discussion of the...

Description
The feasibility of operating an acoustic echo sounder in an urban or industrial environment, without serious degradation in performance and without contributing to noise pollution, is confirmed. Anechoic absorbers placed about the acoustic antenna are the key to improving the sounder performance. Optimum operating frequencies are between 1 and 2 kHz. The design and operation of the all solid state circuitry is described.

Description
The imagery data obtained from earth satellites are well known and applied extensively in the meteorological field. Although these applications are well published, considerable effort is required by a researcher to obtain information on the extent and varied uses of meteorological satellite data. This report is a review paper which brings together in one place summaries and examples of present research and applications utilizing meteorological satellite...

Description
Total field magnetic anomalies can be computed for groups of two-dimensional bodies of irregular cross section by assuming each body to be either bounded by a bundle of magnetic pole lines or enclosed by a set of planes within which the surface density of magnetic poles is a constant. Increasing the number of pole lines through use of an interpolator improves the quality of the pole-line method and makes it very useful for computing the anticipated...

Description
A study has been made to use the differences between the decay of electric and magnetic fields near lightning strokes to determine the distance from a single station to the lightning. In our analysis a model of a return stroke is used to compute the waveform of electric and magnetic fields, between l km and 100 km distance, and the associated frequency spectrum. At distances small compared with the length of the return stroke channel, the electric...

An electrochemical concentration cell (ECC) ozonesonde has been developed for measuring the vertical distribution of atmospheric ozone up to about 35 km. The sondes are normally flown coupled to NOAA National Weather Service or Air Force military type balloon-borne meteorological radiosondes; although, provision has been made in certain models of the instrument for additional coupling to Mastenbrook frost point hygrometers or Suomi-Kuhn net radiometers....

Description
Some consequences of SST engine emissions in the lower stratosphere are considered. Projected emission quantities of H₂O, CO, CO₂, NOx, SO₂, soot, and unburned hydrocarbons are compared with naturally occurring quantities of these substances. There is some present evidence that emissions from the SST will not produce measurable changes in the stratosphere. However, the very restricted knowledge of some stratospheric and operational parameters...
