Air traffic is associated with the emission of high numbers of UFPs, which results in increased UFP number concentrations close to airports. So far, the spatial distribution and variability of UFPs is poorly understood  in the atmospheric boundary layer. The uncrewed aerial system (UAS) ALADINA (Application of Lightweight Aircraft for Detecting In-situ Aerosols, e.g. Altstädter et al., 2015) was operated close to the largest airport in Germany at Frankfurt airport (FRA) between 11 and 19 October 2024. The dataset provides airborne in-situ observations of the spatial distribution of aerosol particle number concentration with different sizes and meteorological parameters of temperature, humidity, wind, surface temperature and short-wave irradiance, as well as accurate position and orientation of ALADINA. Data are available from 26 measurement flights, comprising a number of 122 vertical profiles between ground and a maximum altitude of 750 m above mean sea level (ASL) and about 70 horizontal legs at different but constant altitude, e.g. in 100 m altitude intervals. Details about the ALADINA measurements will be provided in a publication (Harm-Altstädter et al., in prep.) soon.</description><description descriptionType="TechnicalInfo">This research was carried out as part of the UFP exposure study SOURCE FFR (Study On Ultrafine Particles in the Frankfurt Airport Region) commissioned by the Umwelt- und Nachbarschaftshaus (UNH).</description></descriptions><geoLocations><geoLocation><geoLocationBox><westBoundLongitude>8.555698</westBoundLongitude><eastBoundLongitude>8.571759</eastBoundLongitude><southBoundLatitude>50.074879</southBoundLatitude><northBoundLatitude>50.079555</northBoundLatitude></geoLocationBox></geoLocation><geoLocation><geoLocationPlace>Frankfurt-Schwanheim</geoLocationPlace></geoLocation></geoLocations></resource>
