摘要

Dual-Doppler lidar and heliborne sensor were used to investigate the three-dimensional structure of the wind field over Sendai Airport in June 2007. We applied a variational method developed for multiple Doppler radar measurements to dual-Doppler lidar analysis. The comparison of wind fields retrieved from dual-Doppler analysis to wind fields measured by the JAXA heliborne sensor reveals differences of horizontal wind speed and wind direction of 0.11 m s~(-1) and 10.1°, on average, with standard deviations not exceeding 0.75 m s~(-1) and 16°, respectively.
