The assimilation results using an imposed OIMF based on a different ocean conductivity. The top left plot shows the final NRMSD between the rescaled and true OIMF anomalies, and in the top right, the corresponding uncertainty of the determined scale factor is shown. In the bottom left, the assimilation improvement demonstrates how the imposed deviations are changed through assimilation (presented as the difference between imposed NRMSD and rescaled NRMSD). As a comparison, the bottom right plot shows the best possible improvement by an optimal scaling
