Book Description
An analysis was made of the Satellite Temperature Sounding Technique to determine the extent of temperature errors arising from possible atmospheric CO2 variations. These possible errors are compared to probable ozone-caused errors and to errors resulting from the radiometer uncertainties.

Book Description
The general five-parameter band model for molecular absorptance in the infrared is used in the generation of numerous model variations in order to perform a feasibility analysis of band model representation of the 15-micron CO2 band. The accuracy of the models is evaluated by comparisons with the original line-by-line calculated spectra for vertical paths through a standard inhomogeneous atmosphere. The medium inhomogeneity is taken into consideration through the use of the Curtis-Godson relations, including moment variations. Line intensity effects are studied with actual intensity data averaged over 5/cm and with the use of a temperature-dependent factor. It is concluded that a band model representation may provide sufficient accuracy to be of value in meteorological applications only if the number and phenomenological nature of the band parameters are allowed to vary significantly throughout the band.

Book Description
Simultaneous measurements of scattered laser energy (6328A) and atmospheric particle concentration within three size ranges were made to determine the distribution of scattered energy as a function of angle and particulate concentration. A high number concentration was provided by a short but intense sand storm which fortuitously passed through the array during the experiment. Single and multiple regression techniques were applied to data taken at the peak of the storm and to that taken after it had subsided. Experimental results were used to derive empirical models in estimating the scattered energy distribution under both high and low background levels of particulate concentrations. (Author).

Book Description
Waves critically affect man in coastal regions, including the open coasts and adjacent continental shelves. Preventing beach erosion, designing and building structures, designing and operating ships, providing marine forecasts, and coastal planning are but a few examples of projects for which extensive information about wave conditions is critical. Scientific studies, especially those in volving coastal processes and the development of better wave prediction models, also require wave condition information. How ever, wave conditions along and off the coasts of the United States have not been adequately determined. The main categories of available wave data are visual estimates of wave conditions made from ships at sea, scientific measurements of waves made for short time periods at specific locations, and a small number of long-term measurements made from piers or offshore platforms. With these considerations in mind, the National Ocean Survey of the National Oceanic and Atmospheric Administration sponsored the Ocean Wave Climate Symposium at Herndon, Virginia, July 12-14, 1977. This volume contains papers presented at this symposium. A goal of the symposium was to establish the foundations for a com prehensive and far-sighted wave measurement and analysis program to fully describe the coastal wave climate of the United States. Emphasis was placed on ocean engineering and scientific uses of wave data, existing wave monitoring programs, and modern measure ment techniques which may provide currently needed data.
