IceCube
A2 Photonic Sensors IceCube

IceCube is an optical sensor manufactured by A2 Photonic Sensors. It measures the surface snow area (SSA) of a snow sample. It illuminates a snow sample at 1310 nm, measures the reflected light, and infers the snow reflectance. The reflectance is then converted to SSA using a radiative transfer model and calibrated reflectance standards. It is used for radiative transfer calculations, snow chemistry studies, snow grain-size analysis, and remote-sensing validation. IceCube has an acquisition time of less than one second and can operate at temperatures down to -40 degrees Celsius.
