Comparison of the model results and observations for two CIR events. Left: rot-2 (DOY = 184 and 191, 2007). Right: rot-11 (DOY = 58–68, 2008). Panels a and b: magnetic field and its fluctuations normalized with respect to the pre-event values (b and δb, gray and green; respectively). Panels c and d: solar-wind flow speed (dashed black) and the inverted CR(t) graph (blue). Panels e and f: observed CR(t) values (blue) compared to the model results based on the behavior of b (dashed gray) and δb (dashed green).
