   <productDescription>The dataset contains the level 1 and level 2 data of vertical stare mode Doppler lidar during the FESSTVaL campaign 2020/2021. The dataset is retrieved from Halo Photonics Streamline XR Doppler lidar 161 during FESSTVaL 2020 and Doppler lidar 146 for FESSTVaL 2021. The data was measured during the period 1 June - 10 August 2020 and 25 May - 30 August 2021 at Falkenberg. The data is structured in folders as level1 and level2, one file per day. L1 data contains the configuration variable of Doppler lidar and the primary variable such as vertical velocity data, attenuated backscatter and intensity data. The vertical velocity variance and the estimated mixing layer height with 30-minute resolution and vertical velocity in 1-minute resolution are stored in L2 data.</productDescription>
   <limitations>The dataset period is only available during the vertical stare mode period. The unavailable period is due to the change in the scanning configuration.</limitations>
