    Abstract: Knowing snowpack stratigraphy is paramount for avalanche forecasting. In many forecasting operations the stratigraphy information comes from manual observations and traditional ramsonde measurements. However, manual assessments are inherently subjective. Ram profiles can help to estimate the amount of erodible snow or identify large weak basal snow layers but lack the resolution necessary for identifying thin or soft layers. To overcome these challenges, digital cone penetrometers such as the SnowMicroPen (SMP) offer accurate stratigraphy data but are often limited by cost and primarily used for research purposes. In contrast, the snow SCOPE developed by PropagationLabs is cheaper, seems user-friendly, swiftly recording resistance profiles, and thus presents a promising alternative. The goal of this study is to objectively evaluate the SCOPE profiles with co-located SMP and standard measurements measured throughout the Alps. Our analysis, which is based on a dedicated matching algorithm, enables us to quantify the agreement with SMP measurements regarding force and vertical positioning.
