An atmospheric phenomenon is considered as 'explained' when we have succeeded in deducing it on the basis of accepted principles of physics. (H. Ertel, Methods and problems of dynamical meteorolo gy,p. l) Until recently, noctilucent clouds were regarded merely as a curious atmos pheric phenomenon, the occurrence of which aroused only limited scientific attention. However, in the last two decades the interest they have been given has markedly increased. The clouds, usually pale blue in colour, may be seen on a clear night at high latitudes. Typical examples are illustrated in the book. Clouds looking like these in daytime would be classified as cirrostratus. What sets noctilucent clouds apart is their occurrence in the middle of the night, their very obvious pale blue colour, and their disappearance into the dawn close to the onset of civil twilight when the Sun is 6° below the horizon. as being set apart from ordinary Noctilucent clouds were first recognized clouds in 1884/1885 and in a series of sightings that followed their return in the summer of 1885. That year marked the beginning of observations and the interpretation of twilight phenomena. The impetus came from the extraordi nary Krakatoa eruption, which was not only one of the most spectacular volcanic eruptions in recorded history, but which also turned out to be a startling event in atmospheric science with repercussions even in our time.

This book is a multi-author treatise on the most outstanding research problems in the field of the aeronomy of the Earth’s atmosphere and ionosphere, encompassing the science covered by Division II of the International Association of Geomagnetism and Aeronomy (IAGA). It contains several review articles and detailed papers by leading scientists in the field. The book is organized in five parts: 1) Mesosphere-Lower Thermosphere Dynamics and Chemistry; 2) Vertical Coupling by Upward Propagating Waves; 3) Ionospheric Electrodynamics and Structuring; 4) Thermosphere- Ionosphere Coupling, Dynamics and Trends and 5) Ionosphere-Thermosphere Disturbances and Modeling. The book consolidates the progress achieved in the field in recent years and it serves as a useful reference for graduate students as well as experienced researchers.

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

"Most naturally occurring optical displays can be seen from an airplane, and some are best viewed while airborne. This book is an introduction to optical phenomena in the natural world - primarily in the atmosphere (or "in the air"). It follows a simple approach that can be understood and enjoyed by readers without scientific training. A variety of optical phenomena are illustrated with photographs and explained with simplified line diagrams and descriptions. These phenomena range from everyday sky and sunset colors to the elusive noctilucent clouds and aurora, as well as a whole world of too-often-ignored occurences such as sun glitter patterns on bodies of water, colorful ringed glories and coronas, rainbows that cling to the clouds below a high-flying airplane, and ice halos that spring up as an airplane passes through high-altitude ice clouds"--

"Meteoric phenomena" is the accepted term for the complex of physi cal phenomena that accompany the entry of meteoric bodies into the at mosphere of the earth (or of any planet). "Meteoric bodies" are usually defined as cosmic bodies observed by optical or radar techniques, when they enter the atmosphere. The limiting sensitivity of present-day radar equipment makes it possible to record meteors of up to stellar magnitude +14, while the most brilliant bolides may reach magnitude -19. On a mass 7 7 scale this corresponds approximately to a range of 10- to 10 g. How ever, met~or astronomy is also concerned with larger objects, namely crater-forming meteorites, or objects that cause large-scale destruction when they arrive through the atmosphere (an example is the Tunguska River meteorite). Consideration of the interaction of such objects with 12 the terrestrial atmosphere extends the mass range to 10 g. On the other hand, scientists studying fragmentation processes in meteoric bod 7 ies have to consider particles with masses less than 10- g, and the use of data from meteoric-particle counters on rockets and artificial satel lites, from microcraters on the lunar surface, and from noctilucent clouds 12 lowers the minimum mass to 10- g. Therefore, the mass range of meteoric bodies, or meteoroids, encompasses 24 orders of magnitude. Although recent years have witnessed considerable development in meteor research, both in the Soviet Union and elsewhere, the main mono graphs on meteor physics were published twenty or more years ago.

This book presents current knowledge on chemistry and physics of Arctic atmosphere. Special attention is given to studies of the Arctic haze phenomenon, Arctic tropospheric clouds, Arctic fog, polar stratospheric and mesospheric clouds, atmospheric dynamics, thermodynamics and radiative transfer as related to the polar environment. The atmosphere-cryosphere feedbacks and atmospheric remote sensing techniques are presented in detail. The problems of climate change in the Arctic are also addressed.
