Models and Observations to Test clImate Feedbacks
The big MOTIF logo
A research project supported by the European Commission under the Fifth Framework Programme and contributing to the implementation of the Key Action Global change, climate and biodiversity within the Energy, Environment and Sustainable Development Contract No: EVK2-CT-2002-00153

(Proposal No EVK2-2001-00263)
The MOTIF project proposes a coordinated approach to use past states of the climate system as a demanding test of the capabilities and reliability of the latest generation of coupled ocean-atmosphere-vegetation general circulation models (OAVGCMs).
The project will capitalise on recent advances in the availability and interpretation of palaeoenvironmental data, and especially the increase in the number of terrestrial and marine records with high temporal resolution. We will produce estimates of the climate at 6 ka and 21 ka with state-of-the-art models, and an assessment of the realism of these estimates through comparison with palaeoenvironmental observations.
The project will identify the role of key subsystems in the coupled climate system (vegetation, ocean, sea-ice) and determine whether the relative importance of specific feedbacks changes under different climates. It will assess the realism of the simulated changes in mean climate and in interannual to multi-decadal variability.
