Book excerpt: Earth is part of solar system and it has some special features, which makes it beautiful and has conditions conducive for the humans to survive on it. It is well known that the main source of energy for the Earth is Sun. So any changes in, of and on the sun, affects the Earth's environment also called as Space weather. Any changes in Earth's atmosphere due to space weather may affect the Earth and in turn, the human life. Like this, there could be many phenomena which could spontaneously occur on the Earth's, in turn affecting the human life directly (seismic activity, variation in Earth's magnetic field, increase in temperature due to greenhouse effect, to name a few)The objective of this book is paying attention to study the short and long term variation over anomaly crest region. The quantitative understanding of low latitude ionosphere is still incomplete. It is needed to explore more therefore. In present work the behavior of characteristics of spread F, sporadic E, variations over the anomaly crest region using some space and ground based experiments. In this work, we are considering the 23rd solar cycle.

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.

Download or read book The Earth s Ionosphere written by Michael Kelly and published by Elsevier. This book was released on 2012-12-02 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth's Ionosphere: Plasma Physics and Electrodynamics emphasizes the study of plasma physics and electrodynamics of the ionosphere, including many aeronomical influences. The ionosphere is somewhat of a battleground between the earth's neutral atmosphere and the sun's fully ionized atmosphere, in which the earth is embedded. One of the challenges of ionosphere research is to know enough about these two vast fields of research to make sense out of ionospheric phenomena. This book provides insights into how these competing sources of mass, momentum, and energy compete for control of the ionosphere. Some of the topics discussed include the fundamentals of ionospheric plasma dynamics; equatorial plasma instabilities; high-latitude electrodynamics; and instabilities and structure in the high-latitude ionosphere. Throughout this text only the region above 90 km are discussed, ignoring the D region entirely. This publication is a good source of information for students and individuals conducting research on earth’s ionosphere.

This book was released on 2013-12-17 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last week of September 1968, ESRIN (the European Space Research Institute) held the ESRIN-ESLAB Symposium on 'Low-Frequency Waves and Irregularities in the Ionosphere' in Frascati, near Rome. The symposium was attended by about 60 participants, including speakers from most of the ESRO member states, the U.S.A., the U.S.S.R., and Peru. The main topics covered were: (a) observations of ionospheric irregularities by radar scattering, (b) scintillations of satellite signals, (c) geomagnetic micropulsations, and (d) whistlers. Both theoretical and observational aspects were treated. In addition, laboratory results on low-frequency waves in plasmas were discussed, emphasis being given to their possible relevance to low-frequency ionospheric phenomena. Finally, a brief presentation (not included in these proceedings) of the ESRO rocket and satellite program was given by Dr. Pedersen of ESLAB. The symposium provided an exchange of information among workers in closely related fields. It was also valuable in bringing together people whose experience is predominantly in ionospheric observations with others whose field of interest is mainly in plasma physics (theoretical or laboratory) - a combination that seemed particularly appropriate to ESRIN's program and functions.

Three months' observations obtained at Brisbane of the scintillations of the 20 Mc/s transmissions from Explorer VII were analyzed in detail. The scintillations have a Gaussian distribution of amplitude and a scintillation rate which peaks at 2 c/s. The phenomenon is mainly a night-time one but some slight activity persists into the daylight hours. There is no evidence of a correlation with sporadic E but the scintillations are found to be associated with both the frequency-spreading and range-spreading types of spread-F. The scintillation activity is found to increase with zenith angle in a manner which can be interpreted in terms of the same system of irregularities, at heights of the order of 200 to 600 km., producing both the scintillations and spread-F. The irregularities are shown to be field-aligned and to have dimensions of the order of 1 km. The irregularities associated with frequency-spreading are found to occur in patches with horizontal dimensions of the order of 100 km. or more. (Author).
