Cloud droplet residual and aerosol measurements from the Arctic Ocean 2018 expedition

The dataset includes cloud droplet residual and whole-air aerosol particle number size distributions from the Arctic Ocean 2018 expedition, for a selected set of cloud events. It also contains other parameters averaged to the cloud droplet residual data time resolution, including meteorological data and aerosol chemical composition data, and some additional parameters, such as cloud event classification and cloud droplet residual number mean diameter groups.
A ground-based counterflow virtual impactor inlet (GCVI) was used to sample cloud particles, while a whole-air inlet sampled both interstitial (non-activated) aerosol particles and cloud particles.
Measurements were performed onboard Swedish icebreaker Oden during August and September 2018 along the track of the Arctic Ocean 2018 expedition in the central Arctic Ocean. These data can be used to study aerosol-cloud interactions in the high Arctic.

Data description
Data are provided for cloud events analyzed in a study by Karlsson et al. (2022).
The data are included in one NetCDF (nc4) file (15 data variables, 6 coordinate variables):
- Cloud droplet residual (GCVI inlet) and aerosol particle (whole-air inlet) number size distributions measured with two different differential mobility particle sizers (DMPSs).
- Time resolution 9 min in 27 diameter bins.
- time_DMPS coordinate is for the GCVI DMPS data.
- time_DMPS_whlr coordinate is for the whole-air DMPS data.
- Other variables in the data file have been averaged to the GCVI DMPS time resolution. These variables include:
- temperature
- visibility
- liquid water content
- aerosol particle chemical composition data.
More information can be found in Karlsson et al. (2022) and the file metadata.
Comments
Complete (not only cloud events) and higher time resolution versions of these data variables, and other related data, can be found in the Bolin Centre Database under the tags AO2018, AO18 or MOCCHA.
Data were collected during the Arctic Ocean 2018 expedition on board the Swedish icebreaker (I/B) Oden, which was organized by the Swedish Polar Research Secretariat.
The Swedish Polar Research Secretariat (SPRS) provided access to the I/B Oden and logistical support in collaboration with the U.S. National Science Foundation. We are grateful to the Co-Chief Scientists Caroline Leck and Patricia Matrai for planning, technical support, and coordination of AO2018, to the SPRS logistical staff and to I/B Oden’s Captain Mattias Peterson and his crew for expert field support.
