This report indexes characteristic parameters of and describes a means of access to 2,320 wind wave frequency-direction spectra observed at the Texaco Oil Company Harvest Platform during calendar year 1994. Located at about the 2OO m depth contour approximately 20km west of Point Conception, California, the platform supports a spatial array of six pressure gauges, data from which are processed with an iterative maximum likelihood directional estimator. Nine parameters are defined, listed, and graphed in time series form: characteristic wave height, peak frequency, peak direction, four circular moments (mean direction, width, skewness, and kurtosis), and two parameters (directional spread and asymmetry) derived from quartile points of directional spectra. Ths report is the second in a series.
The Internal Refractive Index Spectra of Clouds from Forward Scatter Radar Observations
A multiyear series of wind wave frequency-direction spectral measurements has been undertaken at the Field Research Facility of the Coastal Engineering Research Center, U.S. Army Engineer Waterways Experiment Station. Cross-spectra of surface-corrected signals from a spatial array of 16 bottom- mounted pressure sensors have been used in conjunction with an iterative maximum likelihood algorithm to estimate frequency-direction spectra in about 8 m of water, approximately 900 m offshore. This report provides an index of and describes a means of access to 2,683 spectral observations obtained from September 1992 to August 1993. This period represents the seventh year of data collection. In addition to a list of data collection start times, bulk parameters are provided to characterize the observations. Included are characteristic wave height, spectral peak frequency and corresponding peak period, peak wave direction, directional spread, and reflection coefficient. Time series graphs of these parameters, as well as local winds and currents, illustrate some of the salient climatology. Frequency-direction spectra, Wave database, Wave climate, Wind waves.
Index of Vibrational Spectra of Inorganic and Organometallic Compounds
Infrared Spectra of Inorganic Compounds is a comprehensive compendium of reference infrared spectra and empirical spectra-structure correlations of inorganic compounds in the solid phase. The majority of these compounds are (powdered) crystalline solids in which the crystallographic unit cell may contain several polyatomic ions or molecules. This book begins with an overview of the use of infrared spectroscopy in the identification of inorganic compounds. The experimental procedures for scanning the mid-infrared spectra are then described. The spectra are arranged to bring together compounds containing similar anions, in order to facilitate recognition of characteristic group frequencies. The arrangement is based on the position in the periodic table of the central atom in the anion. Two indices are provided, the first containing compounds as they appear in the book in numerical sequence, and the second arranged alphabetically by anion. Characteristic infrared frequencies and band intensities of the different anions are summarized, along with frequency assignments for the fundamental vibrations of complex anions taken from the literature. This monograph should be useful to physicists and inorganic chemists.
Astronomical Spectroscopy An Introduction To The Atomic And Molecular Physics Of Astronomical Spectroscopy Third Edition
The third edition of Astronomical Spectroscopy examines the physics necessary to understand and interpret astronomical spectra. It offers a step-by-step guide to the atomic and molecular physics involved in providing astronomical spectra starting from the relatively simple hydrogen atom and working its way to the spectroscopy of small molecules.Based on UCL course material, this book uses actual astronomical spectra to illustrate the theoretical aspects of the book to give the reader a feel for such spectra as well as an awareness of what information can be retrieved from them. It also provides comprehensive exercises, with answers given, to aid understanding.
