Data sets

Optical aerosol profiles from the Raman Lidar Polly-XT during MOSAiC K. Ohneiser et al. https://doi.org/10.1594/PANGAEA.935539

Custom collection of categorize data from RV Polarstern between 11 Oct 2019 and 30 Sep 2020 R.Engelmann et al. https://doi.org/10.60656/00945b67503743f0

Initial radiosonde data from 2019-10 to 2020-09 during project MOSAiC M. Maturilli et al. https://doi.org/10.1594/PANGAEA.928656

Short summary

In this study, we focus on the potential impact of wildfire smoke on cirrus formation. Aerosol and cirrus observations with lidar and radar during the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition, presented in the companion paper (Ansmann et al., 2025), are closely linked to comprehensive modeling of ice nucleation in cirrus evolution processes, presented in this article. A clear impact of wildfire smoke on cirrus formation was found.
