Snow is the most reflective and thermally insulating natural material on earth, and shields Arctic sea ice from atmospheric and solar forcing. Uncertainties surrounding the overlying snow on sea ice give rise to significant biases in radar-altimetry derived estimates of winter sea ice thickness. This is because we are uncertain how much snow exists on sea ice during winter, and we are unsure how deep the radar waves from satellites can penetrate through it.
