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 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. **Data Details** Data Begins: 2019-07-08\ Data Ends: 2019-09-23 Date/Time PST Standard\ Wind Speed m/s (Site 300 10 m)\ Wind Speed m/s (Site 300 23 m)\ Wind Speed m/s (Site 300 52 m)\ Wind Speed Sigma m/s (Site 300 10 m)\ Wind Speed Sigma m/s (Site 300 23 m)\ Wind Speed Sigma m/s (Site 300 52 m)\ Wind Direction (from) degrees (Site 300 10 m)\ Wind Direction (from) degrees (Site 300 23 m)\ Wind Direction (from) degrees (Site 300 52 m)\ Air Temperature Celsius (Site 300 2 m)\ Air Temperature Celsius (Site 300 10 m)\ Air Temperature Celsius (Site 300 23 m)\ Air Temperature Celsius (Site 300 52 m)\ Relative Humidity percent (Site 300 2 m)\ Relative Humidity percent (Site 300 10 m)\ Atmospheric Pressure (above ground level) mb (Site 300 2 m)\ Air Density (above ground level) g/m^3 (Site 300 2 m)\ Precipitation in (Site 300 2 m)
