3-D coherent Doppler lidar

updated on 12 Nov 2019

A 3-D coherent Doppler lidar system, developed by Mitsubishi Electric Co. (Tokyo, Japan), was installed on the rooftop of A-building of Fukuoka University (33.55 °N, 130.37 °E, 55 m above sea level) in Fukuoka city, and continuous 3-D wind and aerosol (SNR) measurements over the Fukuoka urban area (over the Fukuoka plain) have been conducted there since Nov 2016.
