In this paper, we will present preliminary results from the working group on coupled experiments. We first describe the boundary conditions and the models (section 2) and some aspects of the simulated mid-Holocene changes (section 3) as shown by both the basic PMIP experiments and the coupled OAGCM experiments. In sections 4 and 5, we present the data-sets and the methodology used for the model-data comparisons. We then focus on the evaluation of the coupled simulations over Northern Africa (section 6) and compare them with the basic PMIPAGCMsimulations. Finally we discuss the implications of these results for the future.
