Book Description
This contract between the Air Force Geophysics Laboratory and Utah State University provided for the investigation into the nature of the disturbed and undisturbed atmosphere with particular emphasis placed upon the spectral, spatial, and temporal behavior of atmospheric emission and the controlling stimuli that initiate such emission. A major thrust was concentrated on the development of new instrumentation and measuring techniques and their use in the measurement program, particularly in atmospheric disturbances. (Author).

Book Description
This book sets out to give a rigorous mathematical description of the greenhouse effect through the theory of infrared atmospheric emission. In contrast to traditional climatological analysis, this approach eschews empirical relations in favour of a strict thermodynamical derivation, based on data from NASA and from the HITRAN spectroscopy database. The results highlight new aspects of the role of clouds in the greenhouse effect.

Book Description
Introduces the physical processes and meteorology required to understand the behaviour of light and radiation in the atmosphere. Integrating the treatment of atmospheric optics from the ultraviolet to the microwave, the book presents a detailed overview, together with discussions, on the associated meteorology and atmospheric composition, which gives the meteorological background necessary to deal with the varying conditions found in the real atmosphere. Mathematical details provide a concise description of results thus allowing readers with a knowledge of meteorology or a single wavelength region to comprehend the transmission, emission and scattering in all wavelength regions. Rayleigh and Mie scattering are covered as well as the aerosol and raindrop distributions found in the atmosphere. Detailed models of the atmosphere and the distribution of trace gases are supplied, and finally a chapter is devoted to standardised software and available data bases.

Book Description
This contractual effort consisted of three elements: laboratory studies of key chemical and transfer reactions which are of special interest to atmospheric IR emissions, ground-based field measurements of carefully selected infrared (IR) airglow and auroral emissions, and detailed modeling of the dynamics of atmospheric processes that are not in local thermodynamic equilibrium. Laboratory efforts centered on the production and detection of highly rotationally excited OH. Data sets obtained at the Bear Lake Observatory during MSX satellite data collection over the site were examined in depth. Conducted the preliminary analysis and interpretation of image data collected at Yucca Ridge, CO., during the SPRITES '96 campaign. A photochemical model for the sodium airglow emission was developed during this period. Work unit updated 5 MAR 98. During the update period, effort concentrated on the investigation of newly documented field observations of extreme non-local-thermodynamic-equilibrium (NLTE) phenomena in the IR airglow and auroral emissions. These new IR observations have significant systems implications. During this period, work continued on the development of the turbulent layer detection algorithm. This effort searched for the connection between the generation and breakdown of gravity waves into turbulence, resulting in spatial and temporal structure. Work also continued on the laboratory studies of NLTE atmospheric infrared emissions relating to the infrared background problem.

Book Description
Of prime interest are the radiation data from that portion of the infrared spectrum known as the atmospheric water-vapor window, ranging from about 8 to 12 microns. Infrared signals received by weather satellites and aircraft depend, in clear air, on surface temperature, atmospheric interference and surface emissivity. For the latter, very different data in literature are found for clouds, water, rocks, etc. In this report correct emissivity data were sought in three ways: (1) Reflectivity of polished rock samples was tested in an infrared spectrograph for 5-16 microns wavelength. Using Kirchhoff's law this method yielded emissivities for near normal incidence. (2) Using an 8-13 microns sensitive radiometer and an aggregate, called emissivity box, the emissivity of many surfaces was measured directly. (3) A summer noon time flight of Tiros over the Mediterranean and the Sahara was evaluated.

Book Description
Meeting the need for teaching material suitable for students of atmospheric science and courses on atmospheric radiation, this textbook covers the fundamentals of emission, absorption, and scattering of electromagnetic radiation from ultraviolet to infrared and beyond. Much of the contents applies to planetary atmosphere, with graded discussions providing a thorough treatment of subjects, including single scattering by particles at different levels of complexity. The discussion of the simple multiple scattering theory introduces concepts in more advanced theories, such that the more complicated two-stream theory allows readers to progress beyond the pile-of-plates theory. The authors are physicists teaching at the largest meteorology department in the US at Penn State. The problems given in the text come from students, colleagues, and correspondents, and the figures designed especially for this book facilitate comprehension. Ideal for advanced undergraduate and graduate students of atmospheric science. * Free solutions manual available for lecturers at www.wiley-vch.de/supplements/

Book Description
This report documents research that has been carried out for the purpose of furthering the understanding of infrared emissions in the non-LTE regions of the Earth's atmosphere. Our effort has consisted of developing and exercising computer models of the quiescent and aurorally disturbed atmosphere, analyzing data from rocket and satellite experiments to validate and extend the models, and drawing upon our experience to help plan for the MSX mission. Specifically, we have used our models to simulate data from the SISSI and MAP/WINE campaigns and the CIRRIS mission, perform benchmark calculations to validate radiative transfer algorithms, and study the effects of gravity waves on non-LTE populations and atmospheric cooling in the mesopause region. We have performed spectral analysis on CIRRIS data, and used the models to identify processes contributing to the 4.3 um emissions seen in the data. We present a detailed description of how to use Atmospheric Radiance Code (ARC), the non-LTE code that we employ for these purposes. We also summarize our role in MSX experiment planning, and software development for automated analysis of MSX Spectrographic Imager data.

Book Description
A Nike-Javelin rocket (NJ-74-1) was launched at Poker Flat, Alaska, on 11 Apr 74 at 0801 hours UT during a non-auroral condition. A near-zenith spectral radiance profile was obtained from 54 km to an apogee of 118 km on ascent and from 118 km down to about 85.6 km on descent, using a circular variable filter spectrometer. About 464 spectral scans were obtained during flight, covering the range from 1.7 to 5.4 micrometers at a resolution of about 4 percent. The dominant emission feature was at 4.3 micrometer, which is attributed to the CO2 nu3 fundamental. The upward viewed spectral radiance appeared to range from about 215 MRmicrometer at 54 km to less than the noise equivalent spectral radiance of 3 MR /micrometer at 118 km. In this report are given the first quiet condition (no aurora) rocket data in the auroral zone. (Author).
