Small uncrewed aerial systems (UAS) are versatile tools to probe the atmospheric boundary layer. With single multicopter UAS, vertical profiles of temperature, humidity and wind can be collected. With a fleet of multiple UAS, distributed measurements at most flexible measurement locations are possible. We operate a fleet of 35 multicopters that are capable of turbulence resolving measurements of the three-dimensional wind vector and temperature. The wind algorithm was verified in wind tunnel experiments and validated in multiple field experiments. We show results of the FESST@MOL and FESSTVaL campaign, the TEAMx-pre-campaign 2022 and measurements upstream and in the wake of wind turbines. In all cases, the advantage of simultaneous wind measurements at multiple locations is demonstrated.
