1PCT CO2 simulation error (CESM2.1.4)

[Jie Hsu]

Hi,

I used CESM2.1.4 to run the 1% CO₂ experiment. The component settings are as follows:

1850_CAM60%1PCT_CLM50%BGC-CROP-CMIP6DECK_CICE%CMIP6_POP2%ECO%ABIO-DIC_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD

This corresponds to the B1850 1% CO₂ increase experiment. However, the simulation produced the following error message:

I have also attached the cpl.log file and the run script for your reference.

Thank you for your help.
