Abstract: Clear-air Doppler wind profilers perform poorly in dry, calm conditions when reflectivities are low. One solution to this problem is to use acoustic waves, generated by a collocated acoustic source, as the scattering target ...

Abstract: An experiment to observe the spatial distribution of radio acoustic sounding system (RASS) echo intensity and Doppler shift using the MU radar is described. Various transmitting configurations are used to confirm that the ...

Abstract: An experiment describing the use of a 50-MHz wind profiler Radio Acoustic Sounding System (RASS) to observe the vertical velocity, precipitation, and buoyancy structure of convection is discussed. In most cases the RASS ...

Abstract: New algorithms for removing ground and intermittent clutter contamination from wind profiler data are presented. The techniques use wavelet transforms to ?filter? the contribution of clutter to the wind profiler signals. ...

Abstract: A numerical technique is described for synthesizing realistic atmospheric temperature and humidity profiles. The method uses an ensemble of radiosonde measurements collected at a site of interest. Erroneous profiles are ...

Abstract: Radar wind profilers (RWPs) sense the mean and turbulent motion of the clear air through Doppler shifts induced along several (3?5) upward-looking beams. RWP signals, like all radars signals, are often contaminated. The ...

Abstract: An algorithm to compute the magnitude of humidity gradient profiles from the measurements of the zeroth, first, and second moments of wind profiling radar (WPR) Doppler spectra was developed and tested. The algorithm extends ...

Abstract: AbstractForecasts by mid-2015 for a strong El Niño during winter 2015/16 presented an exceptional scientific opportunity to accelerate advances in understanding and predictions of an extreme climate event and its impacts ...
