Externally forced simulations for the climate of the late-Holocene (2-3ka BP - present), and future climate, shall be undertaken, using
either the ECHO-G or ECHAM5/MPI-OM AOGCMs. Existing simulations of the
mid-Holocene (7-4.5 ka BP) may also be extended. Consistency tests
between these palaeoclimate simulations with climate reconstructions
derived from proxy data shall be undertaken, using statistical
downscaling and regional model simulations for particular periods.
This work aims to reduce uncertainties in climate reconstructions and
to validate climate models. As part of the ongoing work into the DATUN
(Data assimilation through upscaling and nudging) methodology,
atmospheric circulation reconstructions derived from long instrumental
records and palaeoclimate proxy data will be assimilated into the
ECHO-G coupled atmosphere-ocean GCM. The aim of this work is to bring
together proxy or instrumental data and numerical model simulations
to gain an improved estimate of past climate variability.
