Warming rather than cooling over the last millennium using CESM-LME

[ReiChemke]

Hello,

We are trying to reproduce the CESM LME 850-1849 runs. We followed the instructions here: https://www2.cesm.ucar.edu/projects/community-projects/LME/LME.850-1849.B1850C5CN.pdf, downloaded all the forcings files listed here: Instructions | Community Earth System Model. And integrated the CESM model using version 1.1.2 on our local cluster. The model runs smoothly (including the editing of the user_nl_clm every 250 years). However, we do not get the same climate evolution as in CESM LME, instead we get warming rather cooling over the last millennium. I am attaching a figure with the GMST evolution.

Any ideas on where this bias might be coming from?

Thank you,
Rei

Dear Dr. Chemke,

I hope this message finds you well. My name is Qianye Su, and I am a student from China with a keen interest in your research area. I have experience running CESM2.1.3 and am very enthusiastic about the opportunity to further my studies under your guidance.

Could you please let me know if you are currently accepting PhD students? I am eager to contribute to and learn from your research team.

Thank you very much for considering my inquiry. I look forward to the possibility of working together.

Best regards,
