Figure 1. Snowpack (blue) with slightly undulated snow surface and layers. Waves incident at nadir angle θ n are refracted at the snow surface followed by volume scattering with backscatter σ d 0 (left)
Figure 2. Geometry of the n-layered snowpack with up- and down- down-welling intensities A and B
Figure 3. Left: snow-pit overview with the locations of the SnowMicroPen (SMP) measurements (arrows) surrounding the  pro-file wall (black rectangular)
