The project aims to improve the methodology for reconstructing Quaternary climate. Climate reconstructions offer the only way of quantifying past climate variability beyond the instrumental period. They are essential for validating climate models which can test hypotheses about processes of climate change and provide scenarios for future climate change. Botanical fossils (pollen and macro remains) are well suited for climate reconstructions, because plants strongly depend on climate. This project aims at implementing and testing an advanced reconstruction method based on Bayesianstatistics which is robust against no analogue situations of past vegetation, but enables reconstructions to be as precise as possible. Reconstructions will be performed and evaluated with the new approach and with established methods for European Late Glacial and Holocene records. The reconstructions are expected to be of great value for data-model comparisons.

该项目旨在改进重建第四纪气候的方法。气候重建提供了唯一的方法来量化过去的气候变率超过仪器的时间。它们对于验证气候模型至关重要，这些模型可以检验关于气候变化过程的假设，并为未来气候变化提供假设。植物化石（花粉和大型遗迹）非常适合气候重建，因为植物强烈依赖于气候。该项目旨在实施和测试一种基于贝叶斯统计的先进重建方法，该方法对过去植被的无模拟情况具有鲁棒性，但使重建尽可能精确。重建将进行和评估的新方法和欧洲晚冰期和全新世记录的既定方法。重建预计将是非常有价值的数据模型比较。
