The data set provides measurements of wind direction, wind speed, and vertical wind based on the unmanned research aircraft ALADINA (Application of Light-weight Aircraft for Detecting IN-situ Aerosol) that was used for a field application in Ny-Ålesund, Spitsbergen, between 24 April and 25 May 2018. 49 measurement flights were performed that consist of vertical profiles (in sum 230) with a total maximum altitude of 850 m above mean sea level (AMSL) above land and horizontal legs (around 300) that were operated at different heights crossing the coast, as well as above open. Measurements are provided with a data rate of 100 Hz, which allows processing the data for e.g. turbulence properties. As the quality of wind measurements was deteriorated during flight manoeuvres, wind measurements during unsteady flight states are not contained in the data set, and the data user will need to handle these data gaps within the measurements. Wind measurement is done by fusing the attitude and velocity information from the inertial navigation system and airflow measurements using a multi-hole probe. Further details on the particular set-up of the UAS ALADINA are found in Bärfuss et al. (2018).
