Palaeoclimate reconstruction
1. `Pseudo-observations' based on proxy measurements have a
high spatial resolution, but sparse coverage, and can be rather
inaccurate
2. Climate simulator runs have full coverage but low spatial
resolution, and there is the problem of simulator limitations
. . . Can we construct a synthesis of these two sources of
information which combines their strengths?
This is a very generic problem. A statistical solution emphasises
the assessment and role of uncertainty, represented probabilistically.
