The evolution of the scale factor over the entire assimilation period. The convergence of the scale factor is considered in two different areas: an area of high OIMF variability located in the Southern Indian Ocean (left side) and an area of low OIMF variability located in the Eastern Pacific (right side). The grey lines denote the point-wise local factors, and the red lines highlight the area’s spatial averaged mean and uncertainty (posterior standard deviation). The horizontal, dashed, black line indicates the true scale factor
