Constraints for Rotor Inflow Benchmarks - Unstable Cases

Data to be used as constraints for the rotor inflow benchmarks (unstable cases) as defined in https://rotor-inflow-benchmark.readthedocs.io/

GL*.csv : time-averaged wind speed and veer over each period, obtained from ground-based vertically profiling lidar

UVW*.nc : high-frequency (20 Hz) time series of three-dimensional wind velocity vector over 24 hours centered on the periods of interest, obtained from meteorological tower sonic anemometers Note: the .nc extension here is a mistake; this is a csv. Please load it appropriately e.g. pandas.read_csv in python. We are choosing not to release a new version of the data just to correct a file name extension.

NL*.nc: low-frequency (1 Hz) time series of longitudinal wind velocity over each period, obtained from nacelle-mounted scanning lidar after quality control, temporal upsampling, interpolation to a regular grid and the use of a machine learning model to fill in gaps introduced by blade passage in front of the lidar

LES*.nc: low-frequency (1 Hz) time series of longitudinal wind velocity over each period, obtained from large-eddy simulations performed to match the experimental field measurements
