Data collected by a drone backpack for air quality and atmospheric state measurements during Pallas Cloud Experiment 2022 (PaCE2022)

Abstract. A lightweight, custom-built drone backpack for air quality and atmospheric state variable measurements, mounted on top of consumer-grade drone, was used during the Pallas Cloud Experiment (PaCE) campaign's intensive operation period (IOP) between 12 September and 10 October 2022. The drone backpack measurements include 63 vertical profile flights from two close by locations at Pallasjärvi lake and 12 intercomparison flights against reference instrumentation at Sammaltunturi station. The observations include aerosol number concentrations and size distributions and meteorological parameters (temperature, relative humidity, pressure, and wind speed and direction) up to 500 m above ground level. The dataset has been uploaded to the common Zenodo PaCE 2022 community archive (https://zenodo.org/communities/pace2022/, last access: 5 June 2025). The datasets are available in two formats, NetCDF and CSV, from https://doi.org/10.5281/zenodo.14780929 (Brus et al. 2025a) and https://doi.org/10.5281/zenodo.14778421 (Brus et al. 2025b), respectively.
