Synchronous observation of wind profiles with mobile Doppler lidar

Abstract

Abstract:

Doppler wind lidar is able to measure atmospheric wind field with high spatial and temporal resolution. A mobile Doppler wind lidar for wind profile and three-dimension wind field measurements was developed by Ocean University of China and then operated by China Meteorological Administration. In order to verify the measurement performance of the lidar, a synchronous observation campaign with the mobile lidar and radiosonde was carried out in the Spring of 2011 and obtained 55 intercomparison measurements. This paper introduces the synchronous observation campaign, shows a case study of wind profile intercomparison by lidar and radiosonde, and statistically analyzes all the intercomparison measurements. The results of the synchronous intercomparison shows that the root mean square deviation of wind speed measured by lidar and radiosonde is 2.76 m/s. By means of analyzing the deviation, the wind profiles measured by lidar are proved to be accurate.
