Results of calculated surface air temperature anomaly of COSMOS Pliocene experiment 2 in NetCDF format

In this manuscript we describe the experimental procedure employed at the Alfred Wegener Institute in Germany in the preparation of the simulations for the Pliocene Model Intercomparison Project (PlioMIP). We present a description of the utilized Community Earth System Models (COSMOS, version: COSMOS-landveg r2413, 2009) and document the procedures that we applied to transfer the Pliocene Research, Interpretation and Synoptic Mapping (PRISM) Project mid-Pliocene reconstruction into model forcing fields. The model setup and spin-up procedure are described for both the paleo- and preindustrial (PI) time slices of PlioMIP experiments 1 and 2, and general results that depict the performance of our model setup for mid-Pliocene conditions are presented. The mid-Pliocene, as simulated with our COSMOS setup and PRISM boundary conditions, is both warmer and wetter in the global mean than the PI. The globally averaged annual mean surface air temperature in the mid-Pliocene standalone atmosphere (fully coupled atmosphere-ocean) simulation is 17.35 °C (17.82 °C), which implies a warming of 2.23 °C (3.40 °C) relative to the respective PI control simulation.本手稿详述了德国阿尔弗雷德·魏格纳研究所（Alfred Wegener Institute）为上新世模型比对项目（Pliocene Model Intercomparison Project，PlioMIP）开展模拟实验所采用的实验流程。本文对所使用的COSMOS耦合地球系统模型（Community Earth System Models，版本：COSMOS-landveg r2413，2009年）进行了说明，并记录了将上新世研究、解读与天气图绘制项目（Pliocene Research, Interpretation and Synoptic Mapping，PRISM）的中上新世气候重建数据转换为模型强迫场的具体步骤。针对PlioMIP实验1与实验2的古气候时段及工业革命前（preindustrial，PI）对照时段，本文分别阐述了模型配置与自旋启动流程，并展示了本模型配置在中上新世气候条件下的模拟性能通用结果。采用本COSMOS模型配置与PRISM边界条件模拟得到的中上新世全球平均气候较工业革命前参考时段更为暖湿。中上新世单独大气模式（完全耦合大气-海洋模式）模拟的全球年平均地表气温分别为17.35 ℃（17.82 ℃），较对应工业革命前对照模拟分别升温2.23 ℃（3.40 ℃）。
