Book Description
The photochemistry of the earth's upper atmosphere is controlled fundamentally by the incident radiation from the sun, especially the ultraviolet that is absorbed at levels above the tropopause. This atlas presents the incident solar irradiance with the high spectral resolution necessary to calculate the reaction produced when this energy is absorbed by atmospheric molecular gases. Many of these molecules have absorption bands that consist of very narrow lines. Solar irradiance in units of (mu)w/sq cm/A are presented in the wavelength range of 2226 to 2992 A. The curves were determined from high-resolution rocket echelle spectrograms photographed above the earth's atmosphere. Each panel of the atlas covers 14A, with some overlap from panel to panel. The spectral resolution is approximately 0.03A.

Book Description
The widespread tendency in solar physics to divide the solar atmosphere into separate layers and to distinguish phenomena of solar activity from phenomena of the quiet Sun emphasizes the wide ranging diversity of physical conditions and events occurring in the solar atmosphere. This diversity spans the range from a neutral, essentially quiescent atmosphere to a highly ionized, violently convective atmosphere; from a domain in which magnetic field effects are unimportant to a domain in which the magnetic pressure exceeds the gas pressure, and from a domain in which the particle motions are Maxwellian to a domain in which an appreciable fraction of the particles is accelerated to relativistic energies. It is now widely recognized that the chromosphere and corona have a common origin in the mechanical energy flux generated in the hydrogen convection zone lying beneath the photosphere. Furthermore, magnetic field phenomena appear to be as vital to the structure of th~ quiet Sun as to the active Sun. For these reasons it appears desirable to present a unified treatment of the entire solar atmosphere, both active and quiet, in a single volume. On the other hand, such a treatise must be very long if it is to avoid being superficial, and it is very difficult for a single author to write authoritatively on such a wide range of topics.

Book Description
An ultraviolet spectral atlas of different solar features, including sunspots, active regions, and an explosive event is available from the Institute of Theoretical Astrophysics at the University of Oslo. The spectra are based on observations obtained with the U.S. Naval Research Laboratory (NRL) High Resolution Telescope and Spectrograph (HRTS) with the best available spatial and spectral resolution. A listing of the contents of the atlas and an abstract of a paper describing the atlas are available.

Book Description
Infrared Solar Physics contains the proceedings of the 154th Symposium of the International Astronomical Union held in Tucson, Arizona, March 2--5, 1992. Aimed at active workers and graduate students in solar physics, this volume provides the first comprehensive view of a rapidly expanding discipline that gives us a new perspective on the sun. Measurements across the wide infrared spectral range -- here, from 1 mum to 1 mm -- can probe the solar atmosphere from below the visible surface through the outer reaches of the corona. Taking full advantage of revolutionary advances in detector technology, infrared observations from the ground, aircraft and space have led to a better understanding of solar magnetic fields, atmospheric structure and activity, and elemental abundances. The infrared has also provided new interpretive challenges, such as the appearance of the 12-mum emission lines of magnesium. These and other developments are discussed here by the leading contributors to the field, who also give their perspectives on the future of this rich field of study.
