<p>Halo-Photonics Streamline XR doppler lidar measurements performed using several scan configurations (Velocity Azimuth Display – VAD and Doppler Beam Swing – DBS) and elevation angles of 60° and 80°, are compared to wind observations conducted by various in situ instruments (tethered balloon, meteorological mast, and radiosondes). Good agreement is obtained, with an R<sup>2</sup> over 0.90 for wind speed and a standard error <=18.90° for wind direction for the VAD scan method. Best performance was attained with VAD and lower elevation scans (60°). These results are consistent with the higher spatial lateral homogeneity exhibited by lower angle scans. The boundary layer structure along a diurnal cycle is analyzed by utilizing retrieved backscatter data and wind measurements in conjunction with WRF simulations. Presence of multiple inversions which allow the coexistence of different layers within the studied profile is also verified using data acquired by several radiosondes. Synergic use of Lidar data with WRF simulations for low SNR regions is demonstrated.</p>
