BASIC SPACE PLASMA PHYSICS BAUMJOHANN PDF

The blue emission paints the expanding sphere of the original neutral atoms. At F-region altitudes the sun is still visible and the Barium atoms become ionized by solar UV radiation. Once created, the Barium ions start gyrating and are thus bound to a particular magnetic field line. But the ions still move along the equatorial field lines, leading to the formation of the pink striations.

In an effort to achieve this goal, coordinated experimental campaigns, involving aircraft, balloons, rockets, satellites, and ground-based radars and optical instruments, have been conducted on a world-wide basis. These diverse and comprehensive data sets should play a crucial role in elucidating the cause-effect relationships governing the different regions in the solar-terrestrial system.

However, because the data are typically collected at different regions and times, physics-based models of the different solar-terrestrial regions can play an important role by providing a basis for interpreting and synthesizing the extensive data sets. Specifically, they can relate measurements made at different times and places by taking into account time delay effects. The main goal of this effort was to identify physics-based ionospheric models that could be made available to the international community in some fashion, either via a collaboration with the model developers on specific modeldata comparisons or via the acquisition of a specific model.

This handbook was assembled in order to identify what ionospheric models exist, what physics and chemistry the models are based on, and how the models can be used. The models cover the D, E, and F-regions at low, middle, and high latitudes. There are global ionospheric models as well as models that describe the self-consistent coupling of the ionosphere to the mesosphere, thermosphere, plasmasphere, and electrodynamics. No: each model is particularly well suited to a certain set of issues and problems.

Many of the models whose complex mathematical details are presented here are available for use by others on the World Wide Web. Some sample results are also presented here. Michael J. John Wiley and Sons, Chichester, U. Asgeir Brekke has used his knowledge, accumulated over a long and distinguished research career on the upper polar atmosphere, to write a comprehensive and authoritative book on the fundamental physics that underpins this subject.

The core of the book is a very detailed and comprehensive description of the physics of the upper atmosphere. There is also a reasonable description of the key elements of the chemistry of the upper atmosphere.

There are even short but accurate descriptions of the greenhouse effect and of the loss of ozone from the stratosphere. There are labelled equations in the book, and three that are not annotated!

Thus the approach of the book is much more mathematical than most other books published on various aspects of geospace in recent years.

The large number of equations is necessary because many of the fundamental principles are derived in a very detailed way. This approach will be particularly valuable to students. The book is well produced, and remarkably free from errors. The figures are carefully selected and complement the text well. At the end of each chapter there are some carefully chosen references that provide further information and a few, not particularly imaginative questions.

As with any book there are some aspects that might have been improved or topics that could have been covered more thoroughly. For example the index is somewhat thin and the description of planetary waves in the mesosphere limited.

This excellent book describes all the key fundamental physical processes of the upper atmosphere. It is excellent value for money, and likely to become the type of book that all self-respecting upper atmospheric scientists will have on their shelves, and use frequently. Then the origin and effects of collisions and conductivities and the formation of the ionosphere are discussed. The first part ends with an introduction into magnetospheric dynamics, including convection electric fields, current systems, substorms, and other macroscopic aspects of solar-wind magnetosphere and magnetosphereionosphere coupling.

The second part of the book presents a more rigorous theoretical foundation of space plasma physics, yet still contains many applications to space physics. It starts from kinetic theory, which is built on the Klimontovich approach. Both, fluid and kinetic theory are then applied to derive the relevant wave modes in a plasma, again with applications from space physics.

Is this book successful in meeting its objectives? Undoubtedly yes-the material is presented in a lucid and systematic way, without beating about any bushes. In the case of the Vlasov equation, the Liouville theorem holds only if collisions and correlations between the particles and microscopic fields can be neglected. Measured distribution functions, macroscopic variables, MHD, the solar wind flow, discontinuities.

This is a most impressive book which will be invaluable when teaching the subject matter. I recommend it highly. Their study and that of the coupling of different regions of geospace is therefore central to the International Solar Terrestrial Physics programme.

In the U. A review of current understanding of this field in this context is the subject of this monograph. The first paper, having ten authors, is an overview of current understanding and outstanding questions; by also summerising the results of some contributed papers they introduce the papers of this book, which are grouped in eight subject areas.

The solar origins of geomagnetic storms 4 papers include events related to solar flares and coronal mass ejections. Large scale solar wind streams, especially if associated with many hours of southward interplanetary magnetic field, are effective in causing magnetic storms. The interplanetary origins of geomagnetic storms 2 papers include shocks; there are marked variations through the 1I year solar cycle.

The role of magnetosphere-ionosphere coupling in magnetic storm dynamics 1 paper focuses on energetic oxygen ion observations made aboard CRRES. At solar maximum, much of the plasma responsible for magnetic storms comes from the ionosphere; however, its energistation acceleration is powered by the interaction of the solar wind with the magnetosphere. The relationship between substorms and storm-via electric fields-is explored 2 papers by R.

McPherron and by G. Rostoker el al. There are 3 papers on computer modelling of magnetospheric processes-R. Wolf et al. Chen et al. Kozyra et al. The impact of a geomagnetic storm on the thermosphere and ionosphere is discussed by T. Fuller-Rowe11 and by G. Prolss, in terms of Universal Time effects due to the separation between geographic and geomagnetic poles , temperature and consequent composition changes, travelling atmospheric disturbances, and effects at low latitudes.

The final section 2 papers is on forecasting geomagnetic storms, using either artificial intelligence techniques or linear time series prediction techniques, plus verification analyses.

In conclusion, I am surprised that no paper here makes reference to C.
