Aerosol particle number size distribution data collected during the Arctic Ocean 2018 expedition

Aerosol particle number size distributions in the size range 10⁠ – 921 nm were measured with a custom built differential mobility particle sizer (DMPS)...

Concentration of particles larger than 2.5 nm collected during the Arctic Ocean 2018 expedition

The concentration of particles larger than 2.5 nm was measured with an ultrafine condensation particle counter (UCPC). The concentration was corrected for...

Data from a modelling study on the importance of Aitken mode particles for cloud sustenance in the high Arctic

This dataset presents the model output from two large-eddy simulation models. The model simulations were performed with the aim to investigate the importance...

Frequent new particle formation over the high Arctic pack ice by enhanced iodine emissions, ancillary data

This dataset contains a collection of ancillary data that were used for the publication Frequent new particle formation over the high Arctic pack ice by...

Mask to identify polluted periods during the Arctic Ocean 2018 expedition

Aerosol and trace gas measurements are strongly affected by the ship exhaust and other human activities (e.g., helicopter flights). Therefore, it is important...

Size distribution of aerosol particles between 2.5 and 920 nm measured during the Arctic Ocean 2018 expedition

The aerosol size distribution was obtained combining measurements from a neutral and air ion spectrometer (NAIS) with a differential mobility particle sizer...

Size distribution of interstitial and total particles between 18 and 660 nm collected during the Arctic Ocean 2018 expedition

The aerosol size distribution was measured with a custom made scanning mobility particle sizer (SMPS), range 18⁠ – ⁠660 nm. Aerosols are important...

Size distribution of neutral and charged particles smaller than 42 nm collected during the Arctic Ocean 2018 expedition

The size distribution of neutral and charged particles was measured using a neutral cluster and air ion spectrometer (NAIS) instrument. The concentration was...

Ultrafine particle concentration measured during the Arctic Ocean 2018 expedition

The ultrafine particle (UFP) concentration is the concentration of particles having a diameter between 2.5 and 15 nm, it is reported in terms of particle...

All-Sky cloud imager data from the high-Arctic ASCOS expedition 2008

An all-sky cloud imager consists of a polished half-spherical dome mirror with a camera on top looking down. The camera takes images of the dome, which...

Ceilometer backscatter and cloud base height measurements from the high-Arctic ASCOS expedition 2008

The height to the lowest cloud base, or to more than one cloud base in the case when the lowest cloud layer does not cover the whole sky, was measured by three...

Ceilometer measurements, FMI, from the high-Arctic ASCOS expedition 2008

The height to the lowest cloud base, or to more than one cloud base in the case when the lowest cloud layer does not cover the whole sky, was measured by three...

Dual-channel microwave radiometer measurements from the high-Arctic ASCOS expedition 2008

Vertically integrated water vapor (PWV) and cloud liquid water (LWP) was measured using a microwave radiometer, simultaneously observing the microwave...

Millimeter cloud radar Doppler moments measurements from the high-Arctic ASCOS expedition 2008

Cloud information data was collected using a ship-based vertically pointing millimeter cloud radar (MMCR), which is a Doppler radar at the Ka-band,...

Multi-sensor cloud microphysics product from the high-Arctic ASCOS expedition 2008
