These datasets contain normalized size distributions (dN/dlogDp) of excited particles of sizes 0.5 to 20 μm (optical diameter). The normalized size distribution datasets are...

These datasets contain the total particle number concentrations of hyper-fluorescent particles of sizes 0.5 to 20 μm (optical diameter). The WIBS measures the size, asymmetry...

Cylindrical snow and ice samples of radii 44 mm, 68 mm, 88 mm and a maximum height of 110 mm were taken from the field using a cylindrical drill and transported to the ship in...

In the designated snowpits, 100cm3 of snow was collected in the field, melted and measured for salinity in the laboratory on board Polarstern. Salinity of the melted snow...

Dielectric permittivity (ε′) and dielectric loss (ε″) measurements were made of discrete snow layers and at fixed vertical intervals. Measurements were made using the Stevens...

We used a regular foldable wooden ruler to measure the height of the snow and the SSL. The ruler was also used for height readings for all other measurements. 0 cm is the...

A density cutter of fixed volume (100 cm3) and known weight was used to measure the density profile of snow/SSL in 3 cm intervals. The height of the sampled volume was recorded...

The snow temperature was measured using a waterproof thermometer with a needle probe. A ruler was used to determine the measuring height. 0 cm indicates the snow-ice interface....

SWE is the amount of water contained within the snowpack. To determine SWE, the snow depth and density are required. Snow depth (HS) is related to SWE by the local bulk density...

For the majority of snowpits the snow surface type was recorded by the observer. The documented surface types include; new snow, rime, surface hoar, glazed, drifted snow, wet,...

A NIR camera allows a measurement of the reflectance of the snow profile wall to identify layers of snow grains with different specific surface area (SSA) with a spatial...

Overview photos were taken when arriving at the snowpit site of interest and before the snowpit was excavated. A standard digital camera (Olympus tough TG-5) was used to...

A Garmin GPSmap 62sc device was taken to each snowpit event to get the location measurement. If no GPS file is found, further GPS details can be retrieved from the SMP...

The small-scale surface roughness is important for scattering of shortwave visible and higher-frequency microwave radiation. A standard digital camera (Olympus tough TG-5) and a...

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 (density,...

Broadband surface albedo over Arctic Ocean sea ice was measured using an unmanned aerial vehicle (UAV) system called Spectra during Leg 5 of the MOSAiC expedition in...
