Abstract:
The Hyperspectral camera Specim IQ measures relative reflectances for 512x512 pixels in 204 bands in a wavelength range from 400 nm to 1000 nm. Within the field of view, there was a white reference placed so that the reflectances can be compared to other datasets. During the MOSAiC expedition, the camera was installed at the remote sensing site on the ice. It was looking at the snow and ice, taking an image every 30 minutes for periods in April 2020 and July 2020. Each data record is a folder (compressed as one file) readable by the Specim IQ software, which is downloadable free of charge from the manufacturer (Specim) after registration.
This dataset is from an experimental setup to explore the use of spatially resolved hyperspectral imaging of Arctic sea ice.
