The Gonio-RAdiometric Spectrometer System (GRASS) is an instrument that records quasi-simultaneous, multi-angle, hyperspectral measurements of the Earth’s surface reflectance. Our project consisted of carrying out multi-angular radiometric measurements of the sea ice at the SERF facility using the sun as a natural illumination source. Measurements of the bidirectional reflectance distribution function (BRDF) of sea ice are rare, yet of paramount importance for the correction and calibration of Earth observation satellite sensors.
