Errors in Second Moments Estimated from Monostatic Doppler Sodar Winds. Part II: Application to Field Measurements

Abstract

In this paper we use the theoretical results presented in Part I of this paper to correct turbulence parameters derived from monostatic sodar wind measurements in an attempt to improve the statistical comparisons made with the sonic anemometers on the Boulder Atmospheric Observatory tower. We first show the approximate magnitude of the error due to spatial and temporal pulse volume separation as a function of mean wind angle relative to the sodar configuration and for several antenna pulsing orders. Sodar-derived standard deviations of the lateral wind component, before and after the application of the spatial and temporal volume separation correction, are presented. The improvement appears to be significant. The effects of correcting for pulse volume averaging derived in Part I are also discussed.
