Abstract: It has long been realized that turbulent mixing of vertical refractive-index gradients is responsible for most clear-air echoes seen by UHF radars. The assumptions that the turbulence is isotropic and homogeneous then let ...

Abstract: Four years of data from three radar wind profilers and collocated anemometers are used to examine the airflow regimes near Juneau, Alaska. Wind direction probability density functions and wind rose histograms show the ...

Abstract: Two independent radar methods for estimating the turbulent eddy dissipation rate ? are applied to a common dataset, and the results are compared. The first method estimates ? from backscattered power and relies on the ...

Abstract: The authors examine measurements of boundary layer height zi and entrainment zone thickness observed with two lidars and with a radar wind profiler during the Flatland96 Lidars in Flat Terrain experiment. Lidar backscatter ...

Abstract: The accuracy of the radial wind velocity measured with a radar wind profiler will depend on turbulent variability and instrumental noise. Radial velocity estimates of a boundary layer wind profiler are compared with those ...

Abstract: A 1991 Study on Observational Systems discussed the need for universities to produce graduates capable of developing the next generation of observing systems and interpreting data from emerging complex sensors. It further ...

Abstract: Boundary layer wind profilers are increasingly being used in applications that require high-quality, rapidly updated winds. An example of this type of application is an airport wind hazard warning system. Wind shear can ...

Abstract: AbstractThe best way to train the next wave of observational talent is through direct experience. In 2012 and again in 2014, students at St. Cloud State University (SCSU) welcomed deployments of professional atmospheric ...

Abstract: The authors describe and present early results from the July_August 1996 Lidars in Flat Terrain (LIFT) experiment. LIFT was a boundary layer experiment that made use of recently developed Doppler, aerosol backscatter, and ...
