Implementing a Time-Varying CO₂ Forcing in CESM 2.1.4 (B2000 Configuration)

[Jie Hsu]

Hi all,

I would like to run a CESM 2.1.4 experiment 500 years using the B2000 configuration, but with a time-varying CO₂ concentration (i.e., a user-defined CO₂ forcing scenario).
Could you please advise which NetCDF file I should modify to implement this?

Thank you!

Hi Haipeng,

I’m experiencing the same issue as described in the following link:

1pct CO2 run increase since 2000 (CESM2.1.4)

Hi, I have been tring to run CO2 1PCT increase since 2000 experiments run using “2000_CAM60%1PCT_CLM50%BGC-CROP-CMIP6DECK_CICE%CMIP6_POP2%ECO%ABIO-DIC_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD”, but there are some problems after submitting case. Cesm.log states “ERROR: flbc_inti: cannot specify...
