the lidar echo obtained by the horizontal scanning are shown in Fig. 5(b).
Although the scanning data are also corrected for the squared distance,
it is not corrected for the elevation angle. Thus, the graphs are plotted
in the beam propagation distance. The basic features of cloud echoes
agree well with the temporal variation in Fig. 5(a), while the spatial
structures of cloud are clearly detected in 9-12 h and 12-15 h by virtue of
the horizontal scanning for the first time. The advantage of the horizontal
