Abstract
Recently, with an increase in the number of high-rise buildings, information about wind velocity at high altitudes has become more important. Boundary layer radar observations were carried out for about three months following completion of improvements in the observation system at the Meteorological Research Institute in Tsukuba. This paper shows the vertical profiles of wind velocity and a comparison with the results of wind profiler and high-rise tower observations, The results indicate that boundary layer radar can observe wind velocity up to an altitude of two to three kilometers and is of great use as a device for collecting wind data at high altitudes.
