Book Description
An analytic representation of the quiet daily variation of the geomagnetic field, Sq, was obtained for the North American region with a mean error of less than 10% of the daily variation range. The month by month 24-, 12-, 8-, and 6-hr Fourier components of the field in H, D, and Z were found to have significant annual and semiannual changes that, in general, agreed with the expectations for ionospheric current sources for the changes. Tables and computer programs are provided from which the quiet field representation may be constructed for any selected North American location. At the equator the Sq(H) variation was over 125 gammas and showed significant equinoctial maxima. At 30 deg to 40 deg the lowest values of Sq(H) (less than 20 gammas) were representative of the region of the ionospheric current vortex. Mid latitude Sq(D) values were about 50 gammas in range. Great enhancements of the daily field, particularly in Sq(H) and Sq(Z) occurred at high latitude with a strong summertime maximum range of about 90 gammas in Sq(H) at about 75 deg lat. Five-degree latitude representation of the quiet daily field change illustrate the variations occuring during the day and in different months of the year. (Author).

Handbook of Geophysics and Space Environments
Author: Air Force Cambridge Research Laboratories (U.S.)
Publisher:
ISBN:
Category : Geophysics
Languages : en
Pages : 728
Book Description
This handbook is a comprehensive collection of data, formulas, definitions, and theories concerning the natural environment. It was written by scientists of the Air Force Cambridge Research Laboratories (AFCRL) which, in 1976, became the Air Force Geophysics Laboratory (AFGL). It was designed to serve a broad spectrum of users: the planner, designer, developer, and operator of aerospace systems; the scientist who will find the tables and figures a convenient reference in his own field; the specialist who needs environmental data in another discipline; and science minded people who seek a summary of space-age environmental research. Revisions of individual chapters and sections of this handbook will be published as additional environmental research efforts pay off in new knowledge.
