Matching instruments to science goalsScience Goal Instruments Wake interaction, merging, meandering Long range scanning lidar, radar, profilers, towers,

balloons Wake recovery and dissipation Radars and scanning lidar to measure wakes,

balloons, towers, profilers to measure turbulence, and ambient conditions. Drones could also be useful.

Wake impingement on downstream turbines Loads measurements, remote sensing (ground and turbine mounted), balloons and profilers out ahead of the wind farm

Deep array effects/internal boundary layer Radar, lidar, drones, towers, profilers, balloons

Atmospheric stability and surface heat flux Satellites, modeling, ceilometers/profilers, radar, lidar, towers

Wind direction, shear and veer Profilers, balloons, radar/lidar Wind plant wake radar, scanning lidar, satellite, airborne

measurements, turbine strain instruments

Momentum transport within, around, above and below the farm
