Temporal and perpendicular baselines for the a ALOS-2, b ascending Sentinel-1, and c descending Sentinel-1 image pairs. The blue circles represent individual SAR acquisitions, and the lines connecting them represent the pairs from which small baseline interferograms are formed. The red lines in (b) and (c) indicate pairs with temporal separation less than 60 days and the green lines indicate those less than 400 days
