The German research programme “Our way to Europe“ (CRC 806) studies the history of the Modern Man in an interdisciplinary framework by using geoscientific and archaeological methods. One aim of the climatological group is the spatial climate reconstruction for Europe by including all available proxy and model data.
This contribution looks at the comparison between model simulations, which are taken from the PMIP3 database, and statistical climate reconstructions based on pollen data. The aim is to optimize the model data by including the probabilistic information of the occurring taxa. This concept will be presented and discussed.
For the Mid-Holocene (6 ka BP), especially summer temperatures change clearly when assimilating the PMIP3 multi-model ensemble to the observed pollen data. In this case, the original PMIP3 simulated temperature data are increased through the inclusion of the paleo pollen data. This happens especially over land. The added value can be detected by the predominantly positive Brier skill scores.
