Lidar - HilFlowS - LLNL WindCube v2 - EOP - Processed Data

Published by Wind Energy Technologies Office (WETO) | Department of Energy | Metadata Last Checked: June 28, 2025 | Last Modified: 2021-10-11T00:00:00Z
**Overview** 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. **Data Details** Data Begins: 2019-07-03\ Data Ends: 2019-09-23 Additional Information, files begin with:\ Timestamp (end of interval)\ Wiper count Available at each level (40 m - 150 m):\ Wind Speed (m/s)\ Wind Speed Dispersion or Standard Devation (m/s) \ Wind Speed min (m/s)\ Wind Speed max (m/s)\ Wind Direction (deg)\ Z-wind or Vertical Wind Speed (m/s)\ Z-wind Dispersion or Standard Deviation (m/s)\ carrier-to-noise ratio (CNR), specified in decibels (dB)\ CNR min (dB)\ Dopp Spect Broad (m/s)\ Data Availability (%)
