| Authors:
R. Kazmann
|
 | Probably the most time-consuming procedure associated with a deep-well disposal project is found in the follow-up, when the operation is monitored to make sure that the injected material has not escaped from the target aquifer. The experimental and theoretical work now underway at Louisiana State University may point the way to effective waste monitoring and provide criteria which will lead to the safe containment of wastes for periods comparable to ... |

Klaus Bibl; Joseph A. Patenaude; Bodo W. Reinisch; LOWELL TECHNOLOGICAL INST RESEARCH FOUNDATION MA
|
| Because of the complexity and extreme variability of the ionosphere, extensive measurements and evaluation of long time series of many geophysical parameters are necessary for the understanding of dynamic effects. Much data analysis and classification must precede attempts to explain trends and variations. Gathering the multi-dimensional information requires sophisticated, reliable measuring instruments and systems. In ionospheric physics these tools must be designed and fabricated by researchers. With the exception of ... |

| An Automatic Method for Deducing D-Region Electron Densities from VLF Sounder Data. |
JAN 1970 |
|
| Authors:
James N. Martin; NAVAL WEAPONS CENTER CHINA LAKE CA
|
| An automatic method for deducing electron density profiles consistent with experimental VLF-LF sounder data is described. The method uses a function optimization algorithm of Rosenbrock to minimize the differences between calculated and observed VLF-LF reflection coefficients. The calculated values are obtained by a numerical integration of the equations for wave propagation in an inhomogeneous, anisotropic ionosphere, and the experimental data is obtained from the Corona Laboratories' multifrequency, vertical incidence sounder. ... |

| Determination of Error Limits on Electron-Density Distributions Derived from VLF/LF Sounder Data. |

| Authors:
C. H. Shellman; NAVAL ELECTRONICS LAB CENTER SAN DIEGO CA
|
| A method is developed for mapping the standard errors of vlf/lf sounder data into error limits on ionosphere parameters determined from the data. In the case of electron-density and collision-frequency distributions the error limits take the form of error 'bands.' Interpretation of these bands is discussed. Results are given for two sets of actual data. An example is given to show the type of result which can be expected when ... |

|
| Authors:
Robert L. Mancuso; Roy M. Endlich; STANFORD RESEARCH INST MENLO PARK CA
|
| Three different aspects of a study to apply objective techniques to tropical weather analysis and forecasting are discussed. In the first section computer analysis techniques are used to analyze radiosonde observations taken by the U. S. Army in South Vietnam. These observations provide an unusually large number of upper-air soundings within a relatively small tropical region. The analyses are made at six-hour time intervals for a number of vertical layers ... |

| OPTIMUM ANTENNA ARRANGEMENT FOR A VLF VERTICAL-INCIDENCE IONOSPHERIC SOUNDING SYSTEM, |
MAY 1968 |
|
| Authors:
Elwin W. Seeley; NAVAL WEAPONS CENTER CORONA LABS CA
|
| A horizontal dipole near the earth is a useful transmitting antenna for vertical-incidence ionospheric sounding at VLF, but interference from a component of the ground wave presents a problem. Equations are derived to show that an angle of plus or minus 16 degrees off the axis of the transmitting dipole is the optimum position for placement of the receiving antennas to avoid this interfering signal.

Eduardo Galdon; OBSERVATORIO DEL EBRO TORTOSA (SPAIN) IONOSPHERIC SECTION
|
| From the data obtained at the Observatory del Ebro, Tortosa from the 40 and 41 MHz transmission of the Satellite Explorer 22 (AE-B, S66) the daily and seasonal variation of the total electron content are studied for the period November 1964-March 1968. With the help of the vertical ionospheric soundings of the same Observatory, the slab-thickness parameter has been deduced and its variation studied for the same period. The results ... |

Observations from eleven network stations spread throughout North America are being published in a series of reports. This fourth volume contains ozonagrams for individual ozonesonde ascents made during the period September 1964 to January 1966. The report also presents a statistical summary of the ozonesonde data for ... |

| Authors:
Shimshon Frankenthal; AMERICAN SCIENCE AND ENGINEERING INC CAMBRIDGE MASS
|
| The interaction of charged particles with the electrostatic and flow fields surrounding a rocket-borne mass spectrometer is considered. The objective is to relate the ambient density of various ionic constituents of the ionosphere to the corresponding currents reaching the spectrometer orifice. The interaction is analyzed at low altitudes where space charge effects can be neglected and at intermediate altitudes where these effects are dominant. At high altitudes, older results corresponding ... |

| Authors:
M. R. Epstein; STANFORD UNIV CA STANFORD ELECTRONICS LABS
|
| An experimental procedure to determine ionospheric-channel amplitude and phase statistics as a function of time and frequency is described. A coherent phase FM-CW sounder is programmed to sweep repetitively and rapidly (relative to ionospheric changes) a portion of the HF spectrum. The IF signal obtained by mixing the received signal with a replica of the transmitted signal possesses the amplitude and phase characteristics of the channel. These two characteristics are ... |

|
| Relying heavily on the Elsasser and Culbertson (1960) computational system, computations of terrestrial radiation incident at a black body interface have been programmed for an arbitrary atmospheric sounding. The program has been applied to a random sampling of 62 radiosondes from the 'Wark-sounding-catalog.' Since Wark et al. (1966) have kindly made available simulated Nimbus II channel 2 and channel 4 specific intensities for these same atmospheres, a multivariate regression was ... |

|
| Project High Altitude Research Program (HARP) is directed toward the use of guns for scientific probing of the upper atmosphere. The attractive features of guns for this purpose are the basic economy of such a system and the high inherent accuracy of guns for placement at altitude as well as accuracy in ground impact. The basic liability for such an approach lies in the very high acceleration experienced by gun-launched ... |

| Authors:
R. L. Murphy; R. B. Fenwick; G. H. Barry; STANFORD UNIV CA STANFORD ELECTRONICS LABS
|
| Two methods of oblique-incidence ionospheric sounding--sweep-frequency cw and pulse--were compared over the 8000-km path from Hawaii to Mass. Three cw frequency sweep rates, 25, 100, and 1000 kHz/sec, were explored at various power levels between 1 and 10,000 w. The pulse sounder employed 100-used, 30-kw pulses at a repetition rate of 50 pulses/sec. The tests were conducted in December 1965. (Author) |

| A procedure has been developed to selectively diagnose upper-air humidity from surface observations and to utilize both diagnostic and radiosonde data in an objective analysis of dew-point spread using the successiveapproximation technique. Northern-hemisphere surfacesynoptic and radiosonde data from August through October 1964 are used to develop diagnostic relationships between surface-observed variables at a single station and the dew-point spread at the 850-, 700-, 500-, and 400-mb levels above that station ... |
