Arctic cloud and aerosol measurements from Zeppelin Observatory, Svalbard, November 2015 to February 2018

Linn Karlsson, Radovan Krejci, Makoto Koike, Kerstin Ebell, Paul Zieger

The dataset includes cloud, aerosol and meteorological data from Zeppelin Observatory, Svalbard, for the period 27 November 2015 to 4 February 2018. This includes cloud residual, aerosol particle, and cloud particle number size distributions and number concentrations, as well as temperature, wind speed, visibility, and some additional parameters.

A ground-based counterflow virtual impactor inlet (GCVI) was used to sample cloud particles, while a whole-air inlet sampled both interstitial (non-activated) and cloud particles.

This dataset can be used to study aerosol-cloud interactions for Arctic conditions.

Data description

The dataset is provided in two NetCDF-4 files. Their headers are also available as corresponding plain text files.

Content of the data files:

• zeppelin-cloud-aerosol-1_part1.nc4 (17 data variables, 5 coordinate variables): Cloud residual and aerosol particle number size distributions measured with a differential mobility particle sizer (DMPS), time resolution 5⁠ – ⁠7 min in 30 diameter bins. Other variables in this file have been averaged to the DMPS time resolution. These variables include cloud particle size distribution, temperature, visibility, wind speed/direction, updraft, Cloudnet target classification, and various parameters related to the analysis done in the study by Karlsson et al. More detailed information can be found in the same publication and in the file metadata.

• zeppelin-cloud-aerosol-1_part2.nc4 (2 data variables, 3 coordinate variables): Aerosol particle number size distributions measured with two other DMPS systems than contained in the first part (overlapping size ranges). These two DMPS systems are synchronised as one, with a lower time resolution than the DMPS in the other file, which is why these data are in a separate file.
