Book Description
A satellite experiment has obtained nadir-viewing atmospheric radiance measurements in the 1100 to 2900 angstrom wavelength region from the polar orbiting satellite S3-4. This report describes the instrumentation, measurement techniques, and initial results. The observed emission is from airglow, solar scatter, and auroral regions. Spectral and spatial measurements previously unavailable have been made for the nitrogen Lyman-Birge-Hopfield emission, vacuum ultraviolet aurora, hydrogen geocorona, tropical ultraviolet airglow, twilight fluorescence nitric oxide spectrum, and night oxygen Herzberg band emission. Low values of the day and night background radiance values have been found; these values can be applied to improved missile detection techniques. Spatial resolution down to about one kilometer will enable possible variability to be sought. Observations were made in the period March to September 1978. Correlations with other geophysical factors such as solar flux, magnetic index, and seasonal variations will be made after the data base from the experiment is completed.

Book Description
This report describes airglow and stellar observations made on the TEM-1 rocket flight as a part of the Multispectral Measurements Program (MSMP). The observations were in the 1100 to 3000 A wavelength range from 65 to about 230-km altitude, and they include a number of scans of the viewing direction through the earth's horizon. Night airglow emissions observed include the hydrogen Lyman alpha geocorona and the oxygen Herzberg bands. A number of stars were observed including alpha-Eridanus, which is found to match previous intensity measurements. The instrumentation consists of filter photometers with 10 x 10 element digicon spatial detectors and a spectrometer using a 1 x 36 element digicon for spectral resolution. The report describes the instrumentation, discusses the observations, and compares the results with previous measurements. (Author).

Book Description
Data concerning the spatial and temporal inhomogenities of atmospheric density and composition and their implication concerning the atmospheric infrared radiance are reviewed. Preliminary estimates of the variability in the radiance are presented. In addition, the range of scale sizes from small-scale variations is also considered.

Book Description
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
