**Overview** Wind and lidar turbulence profiles from 40 m to 220 m above the surface. **Data Quality** These two-minute-averaged data files consider the 1 Hz line-of-sight measurements that pass the -22 dB CNR quality control threshold. **Uncertainty** Line-of-sight measurements are converted to horizontal wind speed by assuming horizontal homogeneity in the measurement volume (as discussed in several publications, including Rhodes and Lundquist 2013 and Lundquist et al. 2015). In inhomogeneous flow, this assumption may not be valid. These instruments were sited to avoid breaking the horizontal inhomogeneity assumption, although the Gordon's Ridge sight may be problematic in this respect.
