Download or read book Riometry as an Aid to Ionospheric Forecasting written by Raymond J. Cormier and published by . This book was released on 1970 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report deals with the use of riometers as an aid in ionospheric forecasting during both disturbed and undisturbed conditions at various geographical regions of the earth. Both the physical and technical aspects of riometry are discussed. Riometer observations during special solar geophysical events such as polar cap absorptions, auroral absorptions, and solar flare effects are presented and discussed. Suggestions for the improvement of riometer output and a description of experiments to be performed using riometers as an integral part of forecasting systems are presented. (Author).

Download or read book Thule Riometer Observations of Polar Cap Absorption Events 1962 1972 written by Raymond J. Cormier and published by . This book was released on 1973 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polar Cap Absorption (PCA) events have been observed at Thule, Greenland, using a ground-based riometer for the past decade. The riometer was operated at a fixed frequency of 30 MHz, and used a two-element Yagi antenna directed toward the zenith. This report provides information for operational systems personnel and systems designers concerning the mean behavior of PCAs and other aspects of the phenomenon; for example, the extreme cases in duration and magnitude. In addition, included as an appendix are plots of dB absorption and proton flux (obtained from satellites) versus time for each event. The total number of events is 29. (Author).

Shea and published by . This book was released on 1974 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Campaign for Integrated Observations of Solar Flares (CINOF) was a period of extensive solar flare studies conducted 5-29 June 1972. During this period two discrete solar particle injections occurred, in addition to which significant modulations to the low energy solar particle background flux were present. This report contains fifteen individually authored papers presenting the x-ray, solar particle, and other related interplanetary and geophysical measurements obtained from 28 May - 30 June 1972. A final paper summarizes the particle measurements for the eleven particle enhancements identified during this period.

Book excerpt: At Goose Bay, Labrador, 30-MHz riometers using a four-corner reflector antenna have been in operation since November 1971. An 18-MHz riometer using a zenith-pointing antenna has been operational since June 1972. A quiet day curve of 30 MHz has been constructed for the Goose Bay 30 MHz, and useful hours of operation for an 18-MHz riometer at this particular site are discussed. The usefulness of the four-corner reflector antenna over a single zenith-pointing antenna is discussed, in particular, in an auroral environment. Examples of data illustrating the performance of the antenna system are presented. The data selected are for the geomagnetically active period of mid-April to early May 1973. (Author).
