Book excerpt: Published data on the equatorial airglow are critically reviewed. A number of new results, based primarily on data collected during the IGY, are presented for the oxygen green line and the sodium line. It is shown that the diurnal variation of the green line in equatorial regions is markedly different from that in temperate latitudes. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Radio wave and optical experiments were conducted in March 1977 and March 1978 at low magnetic latitudes to investigate the effects of F region electron density irregularities on transionospheric communications links. Imaging photometer, ionosonde, 50 MHz backscatter radar and satellite amplitude scintillation measurements were used to arrive at a description of equatorial F-region disturbances. After sunset, regions of low electron density propagate from the bottomside, through the F-region peak and often reach to 1000 km altitude. These regions of low density, called bubbles or plumes, are visible as depletions in the 6300 A OI airglow; therefore, the size and motion of these depletions can be measured with an all sky imaging photometer. Electron density irregularities, with scale sizes from 3 m to 10 km, are found within these plumes, and give rise to amplitude scintillation, 50 MHz backscatter and spread F. This report presents a review of the experimental measurements used to arrive at the current description of equatorial F region plumes and associated irregularities. (Author).

This book was released on 2021-05-11 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive review of global ionospheric research from the polar caps to equatorial regions It's more than a century since scientists first identified the ionosphere, the layer of the Earth’s upper atmosphere that is ionized by solar and cosmic radiation. Our understanding of this dynamic part of the near-Earth space environment has greatly advanced in recent years thanks to new observational technologies, improved numerical models, and powerful computing capabilities. Ionosphere Dynamics and Applications provides a comprehensive overview of historic developments, recent advances, and future directions in ionospheric research. Volume highlights include: Behavior of the ionosphere in different regions from the poles to the equator Distinct characteristics of the high-, mid-, and low-latitude ionosphere Observational results from ground- and space-based instruments Ionospheric impacts on radio signals and satellite operations How earthquakes and tsunamis on Earth cause disturbances in the ionosphere The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Available in PDF, EPUB and Kindle. Book excerpt: Raylegh's published data on the airglow green line covering an entire sunspot cycle have been little used because of the manner of presentation. These data have been reexamined and the results for the different stations put on a common basis and converted to present-day units. The assumptions and constants used by Rayleigh in his absolute calibration have been carefully checked, with a resulting small change in the absolute intensity that he had reported. Since Rayleigh worked with wide bandpass filters, a discussion of current knowledge of the night-sky continuum and its correlation with the green line has also been included. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to the use of the ultraviolet for remote sensing of the Earth's atmosphere. It covers the Earth's UV radiative environment, experimental techniques, and current applications. it is my intention to provide the information needed to "make a first approximation" concerning the use of the ultraviolet and to provide access through the literature for a more thorough study.* Contains recent UV applications not previously available in book form such as ozone, auroral images, and ionospheric sensing* Features broad coverage of fundamentals of atmospheric geophysics with values for fluxes, cross-sections, and radiances* Covers techniques that illustrate principles of measurements with typical values* Contains numerous references to original literature
Download or read book Large Scale Optical Mapping of the Ionosphere written by E. J. Weber and published by . This book was released on 1977 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new instrument for all sky, spectrophotometric imaging of aurora and airglow was installed in the Air Force Geophysics Laboratory's Airborne Ionospheric Observatory. Initial observations of equatorial and near-equatorial 6300 angstroms OI airglow show the existence of north-south aligned regions of airglow depletion. These dark bands often extend more than 1200 km in the north-south direction and 50 to 200 km in the east-west direction. Simultaneous airborne ionospheric soundings indicate that these regions of airglow depletion are characterized by an increase in the virtual height of the F-layer. A simple model of field aligned electron density depletion in the bottomside of the F-layer explains both the airglow observations and the ionospheric soundings. Initial auroras zone measurements show the structure and dynamics of the subvisual auroras in the noon sector that result from dayside precipitation. UHF satellite-to-aircraft propagation through the f-region auroras result in amplitude scintillations, both in the noon and midnight local time sectors. (Author).
