UTD 200S: Revealing the Atmospheric Boundary Layer

Since April 21 the UTD 200S LiDAR is performing simultaneous triple lidar measurements, in coordination with the other two scanning lidars, Dalek 1 and 2. A preliminary data analysis shows a rich scenario for the characterization of the thermal stability of the atmospheric boundary layer, including Low Level Jets, Wind Shear, and Convective Cells.
