皮亚琴察中期被认为是一个相对温暖的时期，与现在相比。对皮亚琴察期条件的全面了解既是一个概念模型，也是边界条件的来源，同时也是全球气候模式实验的验证手段。在本文中，我们提出了PRISM4重建，一个古环境重建的中期Piacenzian（类似3马）包含数据的古地理，陆地和海冰，海面温度，植被，土壤和湖泊。我们的追溯古地理考虑到冰川均衡调整和动态地形的变化。土壤和湖泊，都是重要的陆地表面特征，首次引入PRISM重建。海表温度和植被重建没有变化，但现在有信心评估。PRISM4重建被用作上新世模型相互比较项目第2阶段（PlioMIP2）实验的边界条件数据。
The mid-Piacenzian is known as a period of relative warmth when compared to the present day. A comprehensive understanding of conditions during the Piacenzian serves as both a conceptual model and a source for boundary conditions as well as means of verification of global climate model experiments. In this paper we present the PRISM4 reconstruction, a paleoenvironmental reconstruction of the mid-Piacenzian (similar to 3 Ma) containing data for paleogeography, land and sea ice, sea-surface temperature, vegetation, soils, and lakes. Our retrodicted paleogeography takes into account glacial isostatic adjustments and changes in dynamic topography. Soils and lakes, both significant as land surface features, are introduced to the PRISM reconstruction for the first time. Sea-surface temperature and vegetation reconstructions are unchanged but now have confidence assessments. The PRISM4 reconstruction is being used as boundary condition data for the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2) experiments.
