4. What types of plot are
available? As described in the
temperature paper we have constructed various
ways of visualizing the sources of uncertainty:
(a) On the 'Regions' pages there are:
Fractional variance - the fractions of the total variance
contained in each source of uncertainty
Relative error - shows the uncertainty divided by the mean
prediction
Total error - shows the absolute values of the sources of
uncertainty
Total variance - shows the absolute variances of the sources of
uncertainty, stacked.
Signal to noise - shows the mean prediction divided by the total uncertainty
The slider at the top changes the period of time meaning applied to
the temperature predictions. The region can be chosen on the left hand
side, and this will be highlighted pink in the map.
(b) On the 'Maps' pages you can choose the source of
uncertainty in annual, pentadal or decadal mean surface temperatures
and show:
Fraction of total variance
Absolute value of uncertainty
Total signal to noise The lead time can be chosen using
the slider at the top. For precipitation, different seasons can be
selected, but only decadal means are available.
