Abstract
Two 1290 MHz Sodar/RASS instruments have been operated between November 2006 and June 2007 in an industrially used narrow valley with an average crest height of approx. 300 m in Central Austria and in the Austrian flatlands east of Vienna. Vertical profiles of temperature, wind direction and speed, vertical velocity and sigma-w up to a height of 600 m above ground, i. e. well above average crest height at the valley site, have been obtained. Specific features of the valley atmosphere, like the change of wind direction and wind speed with height and the seasonal changes of wind speed and temperature are presented. A comparison of average vertical profiles of wind speed, temperature, and σw shows characteristic differences between the two sites.
