Abstract: | Summary A simple parameterization for the estimation of turbulent kinetic energy (TKE) and momentum flux profiles under near-neutral stratification based on sodar measurements of the vertical velocity variance has been tested using data from the LINEX-2000 experiment. Measurements included operation of a phased-array Doppler sodar DSDPA.90 and of a sonic anemometer USA-1 mounted at a meteorological tower at a height of 90 m. Good agreement has been found between the TKE and momentum flux values derived from the sonic and sodar data (with correlation coefficients r > 0.90 and a slope of the regression lines of about 1.0![thinsp](/content/x9pucj98ggf17b26/xxlarge8201.gif) ![hellip](/content/x9pucj98ggf17b26/xxlarge8230.gif) 1.1) suggesting the possible use of sodar measurements of w 2 to derive turbulence parameter profiles above the tower range. |
