Abstract: Root-mean-square error statistics were applied to tower wind data to find the optimum average times of the wind and azimuth to be used as predictors of a 2-min mean wind speed and direction, 0?10 min in the future. The ...

Abstract: Acoustic echo sounder (echosonde) and meteorological tower measurements of the turbulent velocity structure parameters D(r) and Cv2 and the rate of dissipation of turbulent energy ? are compared. The two acoustic Doppler ...

Abstract: We present a theoretical derivation for errors in calculated second moments arising from the temporal and spatial separation between individual wind measurements obtained from three-axis colocated monostatic Doppler sodar ...

Abstract: The Boulder Atmospheric Observatory (BAO) is a unique research facility for studying the planetary boundary layer and for testing and calibrating atmospheric sensors. The facility includes a 300 m tower instrumented with ...

Abstract: An acoustic sounding system placed on the NOAA Ship Oceanographer during GATE provided a unique meteorological data set. Examples of three distinct boundary-layer situations are discussed as they appear on the facsimile ...

Abstract: A boundary-layer categorization scheme based on GATE acoustic sounder data stratifies surface data and tethered balloon data from the NOAA research ship Oceanographer. The results indicate a clear increase in the sensible ...

Abstract: This paper describes an effort to identify instrumental and flow-related contributions to the mean vertical velocity offsets observed by sonic anemometers on the Boulder Atmospheric Observatory's 300 m tower. A simple ...

Abstract: It has recently become clear through advances in both theoretical and experimental meteorology, that improvements in modeling the transport and dispersion of pollutants will require on-site measurements of the atmosphere. ...

Abstract: Measurements of wind speed, wind direction, and the vertical component of turbulence, from four different commercially available Doppler sodars, are compared with similar measurements from in situ sensors on a 300 m ...

Abstract: Data from the Boulder Atmospheric Observatory (BAO) are used to investigate the wave and turbulence structure of the convective atmospheric mixed layer and the overlying inversion. Three cases are discussed, one in ...
