## 6 Conclusions  
In this study, we processed and analyzed Sentinel-1 DInSAR time series data over five years for five study sites (size: 0.15-0.65 km\({}^{2}\), elevation: 2500-3000 m a.s.l.) in the Central Swiss and Austrian Alps using a semi-automated procedure and open source programs to detect small-scale patterns in displacement direction and seasonality. Unlike previous studies, we decomposed LOS displacement from ascending and descending orbit into horizontal E-W displacement and elevation change. Comparison with movement derived from FT and elevation change from DEM differencing showed that DInSAR captures about one third of the total movement, which represents approximately the proportion of the year covered by the DInSAR time series. Accuracies (Pearson R: 0.42-0.74; RMSE: 4.7-11.6 cm; sd: 20-34 cm) are similar to other recent studies (e.g., [PERSON] et al. [34]), indicating that the higher spatial sampling of 5 m did not have a negative effect on the accuracy of the product. Systematic underestimation increases in areas with larger displacement rates (>0.4 m/a) due to phase unwrapping errors preferable at the front or lateral margins of rock glaciers but could be addressed in future by more advanced unwrapping methods such as deep learning based approaches (e.g., [86; 87]). However, our approach can accurately identify variations in velocity, movement direction and seasonal behavior within rock glaciers on the scale of few decameters also in more challenging settings such as areas adjacent to widespread layover and shadow as well as north oriented rock glacier lobes. Based on our results, the lower detectable boundary with 6 day interferogram stacks is at around 10 cm/a displacement, which is exactly the limit for active rock glaciers [15]. Spatial assessment of movement direction and seasonality showed (Pearson R in brackets): (i) Subsidence over rock glaciers increases with elevation. This effect is clearer at larger rock glaciers with a larger root zone where subsidence occurs due to plastic deformation (0.52-0.79). (ii) Increasing horizontal movement at steeper slopes is most likely obscured by the masking of phase unwrapping errors. (iii) Areas with high relative seasonality show little movement in the first 15 to 80 days after meltout of the snowpack and then preferably increasing subsidence (0.30-0.65) during summer. Hence, rising ground temperatures instead of snow melt water availability might trigger processes in these areas. (iv) Within rock glaciers, absolute seasonality increases towards the root zone (0.34-0.59) along with subsidence (0.49-0.8); additionally, acceleration might be not solely caused by the increased melt water availability here but rather by temperature increases or energy transfer of rainwater from the surface into the subsurface. (v) Strong variations in seasonality occur between adjacent and within rock glaciers, indicating that internal factors such as origin, permafrost temperature, ice content or state might additionally affect seasonality. In conclusion, our approach for Sentinel-1 6-day DInSAR time series can be used for outlining active rock glaciers as well as monitoring their dynamics, mostly during snow-free conditions. It could be implemented as a near-realtime warning system for rock glacier destabilization but also for longterm assessment of ongoing permafrost degradation. Direction and seasonality of movement are useful to differentiate rock glacier parts with different dynamics and drivers as well as to potentially identify variations in internal structure. However, more in situ measurements and geophysical investigations are required to link the observed movement variations with other parameters to achieve a more holistic understanding of rock glacier dynamics.
