The data was measured during the period 21 June 2021 through 02 July 2021 at the GM Falkenberg with the SWUF-3D fleet. The data was collected in association to the FESSTVaL field campaign. The data is structured as one file per UAS (level 1) as well as aggregated data from all UAS operating simultaneously in specific flights (level 2).  For level-2 data, time synchronization between individual UAS was done through interpolation. The different flight pattern are named after this convention: Quality: Uncertainty of wind measurement was validated to below 0.3 m/s. Temperature measurement radiation error was corrected with data from the radiation sensor sups_rao_rad02_l1.
