Upwelling longwave flux in air measurements from AWS located on the Werenskioldbreen. The sensors are installed on a mast that is mounted in the glacier ice. During the season, the distance between the glacier's surface and the sensors increases. The station is serviced at least once a year between March and April.

Wind speed measurements from AWS located on the Werenskioldbreen. The sensors are installed on a mast that is mounted in the glacier ice. During the season, the distance between the glacier's surface and the sensors increases. The station is serviced at least once a year between March and April.

Wind direction measurements from AWS located on the Werenskioldbreen. The sensors are installed on a mast that is mounted in the glacier ice. During the season, the distance between the glacier's surface and the sensors increases. The station is serviced at least once a year between March and April.

Relative humidity measurements from AWS located on the Werenskioldbreen. The sensors are installed on a mast that is mounted in the glacier ice. During the season, the distance between the glacier's surface and the sensors increases. The station is serviced at least once a year between March and April.

Hornsund area extracted from different archive data. Detailed description of the source data and accuracy data for glaciers from hydrological basin of Hornsund can be found in: Błaszczyk M., Jania J.A., Kolondra L., 2013: Fluctuations of tidewater glaciers in Hornsund Fiord (Southern Svalbard) since the beginning of the 20th century.

High resolution orthophoto images from Geoeye, WorldView-2 and Pléaides processed in OrthoEngine module of PCI Geomatica. Data format: grid, UTM 33X / EGM 2008. Spatial resolution: 0.5 m (panchromatic and pansharpened) and 2 m (multispectral).

Downwelling longwave flux in air measurements from AWS located on the Werenskioldbreen. The sensors are installed on a mast that is mounted in the glacier ice. During the season, the distance between the glacier's surface and the sensors increases. The station is serviced at least once a year between March and April.

The data contains excerpts from GPR profiles located near snowpits performed on Hansbreen during the spring seasons of 2008, 2011, 2016, 2018, and 2019. (see Grabiec: ‘Synthetic and Actual GPR Data for Improved Snow Structure Analysis on Arctic Glacier’, Fig.1., Tab.1). The GPR profiles consist of 21 traces pre-trimmed to a time window TW=50 ns (TWTT). Profiles 2011_hansIIItest4 and 2011_hansIIItest5 were not pruned due to the original TW<50 ns. The files presented in the collection have not been further processed. A single GPR profile consists of a set of files with the same name and extension: .rad, .rd3, .utm (UTM coordinates), .rep, rad.vm (Mala Geoscience format)
