Download or read book A Study of Tropospheric Refractive Index Temperature Humidity and Velocity Fields Using Electromagnetic and Acoustic Wave Propagation Methods Supported by in Situ Measurements written by Anton G. Kjelaas and published by . This book was released on 1974 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper 1 summarizes the potentials of different electromagnetic and acoustic wave propagation experiments as diagnostic tools in the study of the refractive-index, temperature, humidity and velocity fields in the troposphere. Papers 2 and 3 discuss measurements of horizontal wind velocity using optical line-of-sight propagation techniques. Paper 2 deals with measurements of horizontal divergence while in paper 3 the spectrum of the spatial wind together with the spectrum of air-pressure are used to deduce the propagation speed and direction of progressive gravity waves in the troposphere. Paper 4 deals with the potentials of an array of vertically pointing acoustic echo sounders to study time-dependent structures, especially waves, in the boundary layer. In paper 5 a forward scatter technique (beam-swinging) is used to deduce the vertical spectra of refractive index and air velocity. The influence of atmospheric stability on these spectra is discussed. Paper 6 discusses the spatial structure of refractive index, temperature and humidity in the lowest 2000 m of the troposphere as deduced from tethered balloon measurements.

Book excerpt: Atmospheric turbulence effects on optical (visible-wavelength) and millimeter-wavelength (mmw) wave propagation can be described by the refractive index structure parameter C(N)(2). Field measurements were made in February and August 1988 at U.S. Army Dugway Proving Ground (DPG) to verify mathematical relationships between the optical (visible-wavelength) and millimeter-wavelength (mmw) refractive index structure parameters C(N)2 and three meteorological variables: (1) the temperature structure parameter C(t)(2), (2) the humidity structure parameter C(q)(2), and (3) the temperature-humidity structure parameter C(Tq). Using certain assumptions, these structure parameters can be estimated from measurements of the atmospheric fluxes of sensible heat and latent heat (humidity). The optical C(N)(2) computed for daytime conditions agreed well with the C(N)(2) measured by an optica scintillometer. However, because of the intermittency of turbulence in the stable nighttime atmosphere, the heat and humidity fluxes exhibited considerable variability in space and time. Consequently, the optical C(N)(2) calculated using flux measurements at a point showed considerable scatter about the path-averaged optical C(N)(2) measured by the scintillometer. Both incident short-wave and net radiation were found to be convenient indicators of temporal variations in optical C(N)(2) during the day, but not at night. Keywords: Scintillation, Millimeter-wave, Temperature flux, Humidity flux, Refractive index structure parameter, Temperature-humidity coherence, Climatology. (JG).
