title: NASCENT campaign data for Motos et al. 2023

description: The data are described in detail in the paper "Aerosol and dynamical contributions to cloud droplet formation in Arctic low-level clouds" (https://doi.org/10.5194/egusphere-2023-530, 2023).
This dataset includes particle number size distribution data from two DMPSs, chemical composition data from a Tof-ACSM, updraft velocity from an ultrasonic anemometer and a wind lidar, cloud droplet number concentration from a HOLIMO and meteorological data (wind speed and direction, temperature).
Note that aerosol composition from a filter pack system, organiccarbon massfrom a high volume sampler and eBC concentration from a MAAP are available on EBAS and therefore not included here
