Impact of the sampling procedure on the specific surface area of snow measurements with the IceCube

Julia Martin and Martin Schneebeli

Abstract. The specific surface area (SSA) of snow is directly measured by X-ray computed tomography or indirectly using the reflectance of near-infrared light. The IceCube is a well-established spectroscopic instrument using a near-infrared wavelength of 1310 nm. We compared the SSA of six snow types measured with both instruments. The IceCube measured significantly higher values with a relative percentage difference between 20 to 52 % for snow types with an SSA between 5 to 25 m2 kg−1. There is no significant difference for snow with an SSA between 30 to 80 m2 kg−1. The difference is statistically significant between snow types but not uniquely related to the SSA. We suspected that artificially created particles were the source of the difference. These were sampled, measured and counted. Numerical simulations with radiation transfer solver TARTES confirm the observation.
