Aerosol particles are considered to be one of the main contributors in affecting the feedback mechanisms of the Arctic Amplification. However, to which extent is far away from quantification and this is partly related to a sparse knowledge of the spatial distribution of aerosols, in particular of the vertical distribution in the atmospheric boundary layer. The data set provides measurements of aerosol particle number concentration (for different size classes, above 3 nm, above 12 nm, and in the ranges of 300-500 nm, 500-700 nm and ~700-900 nm) as well as the meteorological parameters of air temperature, air pressure and humidity 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 ... : Brief overview:A full description of the sensors that are installed in ALADINA and the applied methods that were used during the post-processing are provided in Lampert et al. (2020). The meteorological data is complimentary filtered and all available parameters are in 1 Hz temporal resolution, respectively. The aerosol compartment in ALADINA consists of two condensation particle counters (CPC) of the same type (model 3007, TSI Inc.) that are operated with two different detection limits in order to calculate the number concentration of ultrafine particles in the size between 3 and 12 nm. In addition, one optical particle counter (OPC) is used (model GT-526S, Met One Instruments Inc.) that measures larger particles via six different size channels. In this case, the first three channels were selected for particle sizes of around 300, 500 and 700 nm.---File descriptions:Each file consists of the measured and post-processed parameters according to individual flights that were performed with the unmanned research ...
