Divergent sea ice motion breaks the ice and opens fractures and leads. Depending on the air temperature, those open-water areas can quickly refreeze. The open water or thin ice...

During winter, a significant part of the Arctic Ocean is covered with sea ice. Sea ice works as an insulation layer between the ocean and the atmosphere. The presence of leads...

Wind lidar measurements of the atmospheric boundary layer (ABL) were performed during the Multidisciplinary drifting Observatory for Study of Arctic Climate (MOSAiC) from...

This dataset contains information about the state of the central Arctic lower atmosphere during the Multidisciplinary drifting Observatory for the Study of Arctic Climate...

This dataset contains ground-based radiometer observations from the University of Manitoba Surface Based Radiometer (UoM SBR) at 19, 37 and 89 GHz taken during Leg 1 to Leg 5 of...

We present the isotopic dataset of near-surface water vapour, continuously surveyed from the Polarstern research vessel during the Leg 1 of the Multidisciplinary Drifting...

The total snow and ice thickness (distance from the snow surface to the ice-ocean interface) was measured by the electromagnetic induction (EM) method. On MOSAiC transects, we...

The infrared camera (7.5–14 µm) was mostly observing the snow surface and aligned instruments at the remote sensing site during the MOSAiC expedition in the central Arctic,...

During the MOSAiC drift, vertical profiles of turbulence and auxiliary parameters were measured with MSS microstructure profilers manufactured by Sea and Sun Technology,...

The Optical IP Camera was mostly observing the snow surface and aligned instruments at the remote sensing site during the MOSAiC expedition in the central Arctic, saving 4K...

At MOSAiC, we collected snow depths by Magnaprobe - an automated snow depth probe, throughout the seasons, most often alongside electromagnetic measurements for deriving total...

This dataset gives an overview on the hydrographic properties encountered during the Multidisciplinary drifting observatory for the study of Arctic Climate (MOSAiC). It is not...

During the one-year MOSAiC expedition the multiwavelength polarization Raman lidar Polly (POrtabLe Lidar sYstem) (Engelmann et al., 2016, 2021) was continuously operated aboard...

Horizontal ocean currents were measured from drifting sea ice, using an RD-Instruments 75 kHz ADCP (acoustic Doppler current profiler), Longranger, deployed pointing...

The SnowMicroPen (SMP) is a portable device for high-resolution in-situ measurements of penetration resistance in snow and can be correlated to snow microstructure. The...

Raw data acquired by two thermosalinographs (SBE21, SeaBird GmbH) on board RV Polarstern were processed to yield a calibrated and validated data set of temperature, conductivity...

The radar system on board of Polarstern features a rotating antenna that is mounted on the observation deck, above the bridge. The antenna transmit microwave pulses at short...

The dataset includes computed snow water equivalent (SWE) in mm and depth (m) of the snowpack for MOSAiC leg 1 - 3, derived from SnowMicroPen (SMP) penetration force signals....

The IDEAL Ice Force Panel System is a stress sensor system designed for use under harsh conditions, e.g. extreme weather. It is especially suitable for the measurement of...

Snow height was measured by the Snow Buoy 2019S96, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during MOSAiC (Leg 1) 2019/20. The resulting time...
