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 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...
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...
Cloud and precipitation information data was collected using a ship-based vertically pointing Doppler radar at the S-band, adapted to primarily measure...
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...
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...
During the ASCOS expedition the temperatures of the cloud-base, ambient air, and surface were very accurately measured using the Marine-Atmospheric Emitted...
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...
In-situ boundary-layer meteorological observations were made from the ice using sensors hanging under a tethered balloon which was quasi-continuously winched...
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 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 profile data was obtained by sound detection and ranging (SODAR) which transmit audible sound pulses at several wave lengths. Using the Doppler shift of...
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,...
