The scale factor evolution for test case scenario A.2). As in Fig. 5, the evolution is presented over the entire period and for two different areas of high (left) and low (right) variability of the OIMF. Again, both local results (grey) and spatial mean (red) are shown. However, in the assimilation shown here, an exponentially decaying spatial covariance structure is used at the beginning of the assimilation
