Atmospheric turbulence and aerosol measurements in Surface Layer Turbulence and Environmental Science Test (SLTEST) facility in Dugway, Utah from 2019-06-10 to 2019-07-15

Using three Doppler scanning LiDARs, three Optical Particle Counters (OPCs), one Ceilometer, and one 3-D sonic anemometer, atmospheric measurements were conducted at the Surface Layer Turbulence and Environmental Science Test (SLTEST) facility in Dugway, Utah, during the period of 2019-06-10 to 2019-07-15. This unique location provides a natural facility to investigate near walled turbulence for a range of over 240 km streamwise and more than 48km spanwise in favorable conditions. Coupled with the sonic anemometer, the LiDARs provide high frequency and long-ranged simultaneous measurements of wind velocity and atmospheric backscatter field under all atmospheric stability regimes and wind directions. Moreover, the OPCs helps calibrate the simultaneous backscatter measurements from the LiDAR and Ceilometer (vertical profiles) to estimate collocated aerosol concentration throughout the domain range. This unique dataset will help investigate the coupling of a passive scalar in a near-wall turbulent flow under various flow regimes. Simultaneous data have been collected from all these instruments using coupled scanning strategies which provide a unique opportunity to study passive scalar entrainment and coupling with atmospheric turbulence. This dataset contains raw and processed vertical profiles of backscatter from the ceilometer, as well as the instruments user guide, daily quick-look plots, and a Readme file; raw and summary data from the sonic anemometer, in addition to a Readme file and Matlab scripts for processing the data; raw and processed data from each LiDAR instrument and a Readme file; and data for each ceilometer, including data from each of four units measuring at 6 m on the 28m tower.
