Figure 7

Example of forecast correction. The paneels show how the LETKF data assimilation algorithm corrects the background forecasts in Experiment 2 at t = 240, 300, 360 days. The left column shows the mean of the 60-day background forecast mean for the indicated period and the middle column shows the analysis mean after the synthetic noisy MR imaging data have been assimilated. The right column shows a "spaghetti plot" showing the contour, for each of the 50 ensemble members, where the total tumor cell density is one-half of its maximum value.
