Abstract

The Japan Aerospace Exploration Agency (JAXA) has conducted wind measurements over urban <br>canopy  to  build  numerical  wind  model  for  roof-top  heliport  operation  on  high-rise  building. <br>Doppler lidar and the JAXA’s research helicopter which is capable of measuring winds at 40Hz <br>were used to measure winds aloft. In the measurement, larger power exponent of wind speed profile, more  intensive  turbulent  intensity  and  smaller  turbulence  scale  length  were  observed  in  urban canopy  compared  to  the  existing  standard.  These  acquired  data  will  be  incorporated  into  the <br>numerical wind model.
