Fig. 54.1 Mean rank for the
10 ensemble members. The
mean rank over all six IMS
stations is shown
Fig. 54.2 Observed (black
dots) and simulated (blue
lines) activity concentration
(mBq/m 3 ) for the 10
members at the IMS station
NZX46. Observations below
the detection limit were set
to zero
54.4 Discussion
When we compare these results with the scores obtained during the Maurer et al. [1]
intercomparison exercise, it is found that the setup using the ERA5 data results in a
good rank (the median rank for all participants in Maurer et al. [1] was 2.07).
