Figure 6

Results of the observing system simulation experiments after the final assimilation step. The first, second, and third rows show the results of Experiments 1, 2, and 3, respectively, at t = 360 days using the parameter ranges listed in the respective columns of Table 3. The left column shows the final ensemble analysis mean, and the middle column, the pointwise absolute difference between the analysis mean and the "true" tumor. The right column shows the ensemble mean of free runs of the models, i.e., the mean 360-day forecast without data assimilation.
