Change
Under the Analysis sub-menu it is possible to select either Change, Model
(i.e., model baseline) plus Change, or Obs. (observed baseline) plus Change
-- or view the baselines alone. Selecting 'Error' will give the difference,
model baseline (MB) minus observed baseline (OB). For temperature, it is
the difference MB-OB that is displayed. For precipitation, 100*(MB-OB)/OB
is displayed.
