Provides tools and techniques to identify and address distortions and to interpret data coming from Lidar sensing technology This book covers the issues encountered in separating the backscatter and transmission terms in the LIDAR equation when profiling the atmosphere with zenith-directed and vertically-scanning Lidars. Solutions in Lidar Profiling of the Atmosphere explains how to manage and interpret the Llidar signals when the uncertainties of the involved atmospheric parameters are not treatable statistically. The author discusses specific scenarios for using specific scenarios for profiling vertical aerosol loading. Solutions in Lidar Profiling of the Atmosphere emphasizes the use of common sense when interacting with potentially large distortions inherent in most inversion techniques. Addresses the systematic errors in LIDAR measurements Proposes specific methods to estimate systematic distortions Explains how to apply these methods to both simulated and real data Solutions in Lidar Profiling of the Atmosphere is written for scientists, researchers, and graduate students in Meteorology and Geophysics.
The work is concerned with the problem of determining something of the nature of the turbulent atmosphere by studying the perturbations it induces upon a radio-wave which propagates through it. An experimental system is described which operates at a frequency of 34.89 GHz over a 28 km path. The receiver consists of an array of eight horizontally spaced antennas, and the transmitter consists of two horizontally spaced antennas which are time-shared by the receiving array. The data consist of amplitude and relative phase measured at each of the eight receiving points for both transmitters. The transmitters are alternated quite rapidly (relative to the characteristic time of the atmospherically induced fluctuations) so that from the data a variety of propagation geometries may be studied - one-transmitter-two-receiver, two-transmitter-one-receiver, and two-transmitter-two-receiver. The analyses consist primarily of calculating covariances between data channels (with and without time lags) for the various propagation geometries available. (Author).
