The altitude variation of the intensity ofλ 6300 line of OI atom and that ofλ 3914 (0–0 band of the first negative system of N2+) in the day airglow have been calculated. It has been found that photodissociation of O2 by the Schumann-Range continuum is mainly responsible for the emission ofλ 6300 line (intensity 65 KR).

A phenomenological description of the night airglow is presented, reviewing the historical background, and what is known about height, temporal and spatial variations in intensity, and movements. The very important relationship to aurora and evidence for latitude-seasonal effects are examined.

The phenomenology of the night airglow is reviewed with particular emphasis on the work of recent years. The major topics discussed are the spectrum; latitudinal dependency; diurnal variation; correlations in time and space; the effects of magnetic activity and of the sunspot cycle and solar activity; and conjugacy and the airglow.

During the past few years, the study of airglow emissions from tropical latitudes has led to progress in several areas of aeronomic research. The understanding of radiative processes involving recombining atomic and molecular oxygen ions has progressed to the point that F‐region dynamics can be inferred from simultaneous observations of selected lines.

The ionospheric glow is due to the desexcitation of neutral or ion molecules and atoms. Its computation requires the knowledge of a number of parameters including the production of the excited species. Several processes occur: resonant and fluorescent scattering, chemical reactions, recombination, photo-absorption or collisions.

Io is the innermost of the four Galilean satellites of Jupiter. In size, density, and distance from its parent planet it is quite similar to our own Moon. Most of its other physical properties are different from our lunar experience. To gain some familiarization with this satellite, the following brief discussion will highlight some of its observed ...
