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

[Jie Hsu]

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 flbc_cycle_yr if flbc_type is not CYCLICAL”.

I also add these scripts in user_nl_cam:
flbc_type='SERIAL'
flbc_file='/work1/u7719052/4xco2ramp/LBC_1pctCO2_rampup-rampdown.500yr.nc'
flbc_list='CO2','CH4','N2O','CFC11eq','CFC12'

How can I solve this problem? Could I get some advice?

For the better understanding, attaching my cesm.log file below:



Thank you.

Here is cesm.log file.

Hi Jie Hsu,

This error is saying you need to change

flbc_type='SERIAL'​

to

flbc_type='CYCLIC'​

in the user_nl_cam.

Best,
Rebecca

Hi Rebecca,

I also changed 'SERIAL' to 'CYCLICAL' and performed a test simulation for one year, but the new error message still appeared, as shown below.

ERROR: Unknown error submitted to shr_abort_abort.
flbc_inti: time out of bounds for dataset =

Thank you!

If you change
flbc_type='SERIAL'
to
flbc_type='CYCLICAL'

I think you also need to specify the flbc_cycle_yr
For instance:
flbc_cycle_yr = 2000
But this will cycle over one single year.

If you want 1pctCO2, I think you need to use a 1%co2 file. For instance:
flbc_file = '/glade/campaign/cesm/cesmdata/cseg/inputdata/atm/waccm/lb/LBC_CMIP6_1pctCO2ramp_y1-165_0p5degLat_c180930.nc'

Thanks! I got it!
