Each member of the ERA5 ensemble has a roughly equivalent rank. This is a
feature of a good ensemble, where all members are drawn from the same probability
distribution.
It is also shown that there are other sources of uncertainty which could not be
quantified. In this exercise, this was mainly related to the emission uncertainty from
other sources of radioxenon which were not taken into account in the challenge, which
results in an ensemble spread that does not represent therefore the full uncertainty.
