Lidar - HilFlowS - LLNL ZephIR300 - MOP - Processed Data

Published by Wind Energy Technologies Office (WETO) | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-10-11T00:00:00Z
**Overview** 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°. **Data Details** Data begins: 2019-07-12\ Data Ends: 2019-09-23 Additional Information, files begin with: \ Time and Date \ Timestamp (s)\ Battery (V)\ GPS\ Met Compass Bearing (deg)\ Met Air Temp.
