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...
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...
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...
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...
Vertically integrated water vapor (PWV) and cloud liquid water (LWP) was measured using a microwave radiometer, simultaneously observing the microwave...
A subset of reanalysis data, interpolated to the Icebreaker Oden's position during the ASCOS expedition. ERA-Interim data is a reanalysis effort from the ECMWF...
During the ASCOS expedition the temperatures of the cloud-base, ambient air, and surface were very accurately measured using the Marine-Atmospheric Emitted...
Micrometeorological observations were collected from two masts on an ice floe a few hundred meters from the Icebreaker Oden during ice drift of the ASCOS...
Cloud information data was collected using a ship-based vertically pointing millimeter cloud radar (MMCR), which is a Doppler radar at the Ka-band,...
This data set includes retrievals of cloud type, characteristic particle size, and condensed water content for both liquid and ice hydrometeors. These...
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...
Profiles of ozone concentration were measured by a Vaisala add-on ozone sonde, for a few of the radiosoundings launched from the helipad of the Icebreaker Oden.
Profiles of radioactivity were measured by a Vaisala add-on radioactivity sonde for a few of the radiosoundings, measuring Geiger–Müller tube count rates...
High resolution (in time and space) vertical profiles of temperature were obtained from a 60GHz scanning microwave radiometer. The radiometer measures the...
Radiosoundings were launched every six hours (00, 06, 12 & 18UTC), and additionally before each helicopter flight (if not at one of the normal times), using...
Cloud and precipitation information data was collected using a ship-based vertically pointing Doppler radar at the S-band, adapted to primarily measure...
Wind profile data was obtained by sound detection and ranging (SODAR) which transmit audible sound pulses at several wave lengths. Using the Doppler shift of...
In-situ boundary-layer meteorological observations were made from the ice using sensors hanging under a tethered balloon which was quasi-continuously winched...
Incoming and outgoing ultraviolet radiation was measured by a semi-portable sensor with a NILU-UV multiband filter-radiometer. This was sometime located at the...
Visibility data was collected using a Vaisala visibility sensor based on forward scattered laser light deployed on the aft starboard side on the 7th deck of...
The Icebreaker Oden's weather station was mostly located on the 7th deck about 27 m above sea level, on top of the bridge. Sensors were distributed over the...
The WeatherPak station is an integrated unit mounted approximately mid-ship on the forward railing on the Icebreaker Oden's 7th deck about 27 m above sea...
Wind profiler consensus data was obtained using a Doppler radar wind profilers transmitting at 449MHz. Using the Doppler shift of the return signals and...
Wind profiler moment data was obtained using a Doppler radar wind profilers transmitting at 449MHz. Using the Doppler shift of the return signals and algebra,...
Upper ocean gas bubbles generate airborne droplets when they burst at the surface, either "film droplets", from remnants of the surface of a bubble, or "jet...
Profiles of pressure, temperature, salinity, potential density and Turbulent Kinetic Energy (TKE) dissipation rate were measured at the ocean site of the ice...
Upper ocean turbulence data was measured at the ocean site of the ice floe roughly 100 m from the Icebreaker Oden, using instruments mounted in a tower...
Spectrally resolved short-wave radiation was measured at the ocean site of the ice floe; downwelling from the atmosphere, reflected by the surface, and under...
