Code for Mannerfelt et al., (2025): Tracking glacier surge evolution using interferometric SAR coherence — examples from Svalbard

This repo contains code to download InSAR coherence data from ASF Vertex, and tools for plotting / analyzing manual low-coherence front measurements. The main files are query_insar.py (run it directly to start querying all Sentinel-1 InSAR scenes) and surge_propagation.py for all plotting/statistics functions.
