Abstract. Acoustic sounding is a remote sensing technique which may be employed not only for the study of the structure of the lower troposphere, but also for the measurement of wind velocity using turbulent scattering regions as tracers or natural targets. Principles involved in the use of both angle of arrival and Doppler techniques for such wind measurements are summarized. Experimental results, which are presented for thermal plumes, structure associated with airflow over hills and a turbulent region of the radiation inversion, illustrate the potential of the acoustic sounding technique for research into boundary-layer meteorology.
Abstract. Clear-air plume and wave-like structures are revealed in the atmospheric boundary layer by combined acoustic remote sensing and meteorological tower measurements. The magnitude of turbulent production and dissipation plus properties of velocity and temperature spectra determined from the tower measurements are well correlated with phenomena indicated by the acoustic sounder. Interpretation of either set of records is greatly enhanced by the other. For example, the onset of a sudden burst of turbulent production from the tower measurements may correspond to plume passage or breaking of stable waves recorded by the acoustic echo sounder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
