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...

ASCOS — Arctic Summer Cloud Ocean Study

The Arctic Summer Cloud Ocean Study (ASCOS) was a scientific expedition to the high Arctic in summer 2008, during the International Polar Year (IPY), which was...

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...

Micrometeorological data from an ice-floe adjacent to an open lead during the Arctic Ocean 2018 expedition

Fast response (20Hz) measurements of the 3-dimensional wind vector, temperature and humidity, derived micrometeorological variables, and mean meteorological...

Micrometeorological data from icebreaker Oden’s foremast during the SWERUS-C3 Arctic Ocean expedition in 2014

Fast response (20Hz) measurements of the 3-dimensional wind vector, temperature and humidity, derived micrometeorological variables, and mean meteorological...

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

This data set includes retrievals of cloud type, characteristic particle size, and condensed water content for both liquid and ice hydrometeors. These...

Navigation, meteorological and surface seawater data from the SWERUS-C3 Arctic Ocean expedition in 2014

Measurements from icebreaker Oden’s navigation, meteorological and surface seawater systems during the SWERUS-C3 expedition to the Russian Arctic Ocean....

Oden ceilometer cloud data from the high-Arctic ASCOS expedition 2008
