Overview of the Dataset


This data set consists of years 21 - 329 of the 500-year pre-industrial control simulation forced by perpetual 1850 conditions on the Sunway TaihuLight supercomputer at Wuxi, China. The data will be accessible from both the Qingdao National Laboratory for Marine Science and Technology (QNLM) data server and the International Laboratory for High-Resolution Earth System Prediction (iHESP) data server at Texas A&M University (TAMU). Also released is the first fully optimized Sunway version of the Community Earth System Model code, which is publicly available through (https://github.com/ihesp) together with the original version of the code.


The simulation name-tags were based on the CESM1 convention.

Naming Convention - B.E.13.B1850C5.ne120_t12.sehires38.003.sunway
  • B. – CESM Atmosphere, Ocean, Land, Sea-ice and River-transport coupled model
  • E.13. – CESM version 1.3
  • B1850C5. – CESM Component set name
  • ne120_t12. – Short name for the ne120np4_tx0.1v2 grid used by the components
  • sehires38 – Specific SE-dycore high-resolution tag used in the simulations
  • sunway – The Chinese HPC system on which the data sets were generated by the CESM-HR_sw1.0 code.
Simulation Configuration - B.E.13.B1850C5.ne120_t12.sehires38.003.sunway

This Community Earth System Model version is based on CAM5.4/CLM4.0, POP2 and CICE4.0. The cases were generated by CESM create_new scripts and modified using namelist changes. The external forcing uses the same CESM code base.
