Abstract: | A double edge Mie Doppler lidar at 1064 nm was developed in Hefei, China in 2005 for low tropospheric wind measurement. Intercomparison
experiments with a wind profiler and a wiresonde were held. Intercomparisons of concurrent lidar and other instrument observations
show good agreement with expected measurement accuracy. The examples of validated lidar wind profiles obtained during these
experiments as well as an example of continuous wind observations are presented. The instrument has demonstrated the capability
of atmospheric wind field measurement from 0.2 to 5 km altitude, achieving below 2 m/s accuracy with 1 min averaging and 21.2
m vertical resolution. |
