The influence of aerosol particles on the Arctic climate system and their role in the Arctic amplification remains uncertain. Further research is required to gain a broader understanding of the processes that drive or suppress new particle formation along with transport and spatial distribution of aerosol particles, especially in the atmospheric boundary layer. This dataset provides airborne measurements of the aerosol particle number concentration in different size classes alongside meteorological parameters. During the field campaign, the uncrewed aerial system (UAV) ALADINA (Application of Lightweight Aircraft for Detecting In-situ Aerosols) operated from the airport in Ny-Ålesund, Svalbard, between 20 May and 4 June. The 38 measurement flights consist of 143 vertical profiles up to 930 m altitude above mean sea level (MSL) and 62 horizontal flight legs above land and the Kongsfjord at multiple constant altitudes. A detailed description of the AIDA campaign (Aerosol variability and Interaction with ambient conditions based on small-scale vertical and horizontal Distribution of Arctic measurements), the ALADINA system and the applied methods during the post-processing will be provided by Schuchard et al. (in preparation).
