These are 10-min averaged data from a vertical-profiling ZephIR 300 lidar. Data collected at the Arlington airport for the WFIP2 project. March 10, 2016 - April 1, 2017
Data submission for WFIP2 at Vansycle Ridge (Oregon). Vertical-profiling lidar data from a Wind Cube v2, included 10-minute averages of wind speed and wind direction up to 200 m. Data collected during WFIP2.
The WindCube v2 is a pulsed LIDAR and uses four beams sent in succession in the four cardinal directions along a 28°scanning cone angle to measure horizontal velocity and wind direction. A fifth beam is sent in the vertical direction to measure vertical velocity. Measurement heights are user-programmed and range from 40 m to 200 m. During HilFlowS, the WindCube v2 was programmed to measure from 40 m to 150 m at 10-m intervals. The data sampling rate was 1 s, wind speed accuracy was 0.1 m/s, and direction accuracy was 1.5° for the instrument. The data were averaged across 10-min. averaging intervals.
The ZephIR300 is a continuous wave LIDAR with a range of 10 m to 300 m. During HilFlowS the ZephIR300 was programmed to measure from 10 m to 150 m. In addition, the ZephIR300 provided a measurement at 1 m height using an onboard meteorological sensor. The ZephIR300 has a 30° scanning cone angle, data sampling rate of approximately 15 s, wind speed accuracy of 0.5 percent, and direction accuracy of 0.5°.
The WindCube v2 was co-located with Site 300’s 52-m-tall meteorological tower so that measurements below 40 m could also be observed. The meteorological tower has three measurement levels: 10 m, 23 m, and 52 m. Wind speed was measured with a cup anemometer; wind direction with a wind vane. Data are available as 15-minute averages.

This dataset contains vertical profiling lidar data from AWAKEN site A1. This is the ZX300 unit #1381 lidar system. The .csv files are monthly data files with 10-min average data. The .zip files are daily high frequency data and zipped by month.
This dataset contains vertical profiling lidar data from the SGP ARM E36 site. This is the ZephIR-300 unit #345 lidar system. CLAMPS was also deployed at this site for some of AWAKEN during IOPs. This is an upwind AWAKEN site.
This dataset includes large-eddy simulation (LES) output from a convective atmospheric boundary layer (ABL) simulation of observations at the SWIFT tower near Lubbock, Texas on July 4, 2012. The dataset was used to assess the LES models for simulation of canonical convective ABL. The dataset can be used for comparison with other LES and computational fluid dynamics model outputs.
