How to make the mode use downloaded CO2 data

[Ambition_hhh]

./create_newcase --case HistClm50BgcCrop --res f09_g16 --compset IHistClm50BgcCrop --mach myintel --compiler intel --run-unsupported

I created this case, I want the model to use my own file download of co2 (cmip6 download rcp2.6 data)
/home/hlh/cesm/inputdata/atm/datm7/CO2/fgco2_Oyr_CanESM5_rcp26 - cmip5_r1i1p1f1_gn_2006 - 2100.nc

1. I changed it in the run_run.xml file:
<entry id="DATM_CO2_TSERIES" value="none">
<type>char</type>
<valid_values>none,20tr,20tr.latbnd,rcp2.6,rcp4.5,rcp6.0,rcp8.5</valid_values>
<desc>DATM CO2 time series</desc>
</entry>

2. I changed it in the run_run.xml file:
<entry id="DATM_CLMNCEP_YR_START" value="2006">
<type>integer</type>
<desc>starting year to loop data over</desc>
</entry>
<entry id="DATM_CLMNCEP_YR_END" value="2100">
<type>integer</type>
<desc>ending year to loop data over</desc>
</entry>

3. I changed it in the run_run.xml file:
<entry id="CLM_CO2_TYPE" value="diagnostic">
<type>char</type>
<valid_values>constant,diagnostic,prognostic</valid_values>

4. I added to the user_nl_datm file:
co2_type = 'diagnostic'
fgco2_file = '/home/hlh/cesm/inputdata/atm/datm7/CO2/fgco2_Oyr_CanESM5_rcp26-cmip6_r1i1p1f1_gn_2006-2100.nc'
/

But an error is reported:
hlh@hlh-desktop:~/clm5.0/cime/scripts/my_custom_co2_case$ ./case.build --skip-provenance-check
Building case in directory /home/hlh/clm5.0/cime/scripts/my_custom_co2_case

ERROR: Variable 'fgco2_file' from file '/home/hlh/clm5.0/cime/scripts/my_custom_co2_case/Buildconf/datmconf/namelist_infile' is not in the namelist definition.


I found that errors occurred when I added contents in the user_nl_datm file and the user_nl_clm file

How do I get the model to use my CO2 data

Thanks for your answer

Hi,

What version of CESM are you using? It looks like you're using a fairly old version. I would recommend you update to a newer release - Community Earth System Model 2 (CESM2) | Community Earth System Model

你好

您使用的是哪个版本的 CESM？看起来您使用的是相当旧的版本。我建议您更新到较新的版本 - 社区地球系统模型 2 （CESM2） |社区地球系统模型

My version is cesm2.2.0

May be I just get started, do not know how to debug, can you help me to answer?

Thanks for your answer!

For what you are trying to do, I recommend the following troubleshooting steps:
1) Confirm that your version of the model runs without any changes to the files or the code.
2) Confirm that the modified co2 file that you wish to use has the same format as the default one.
3) Now try replacing the default co2 file with yours, and hope that it works correctly.

...but possibly before all that, the error message says that fgco2_file is not a valid namelist variable. You need to find out what it should be.

我的版本是 cesm2.2.0

可能是我刚开始，不知道怎么调试，能帮我解答一下吗？

...但可能在这一切之前，错误消息说 fgco2_file 不是有效的 namelist 变量。你需要找出它应该是什么。

I've tried a lot of names, but I don't understand what a namelist variable is.

Namelist variables are explained in the CESM tutorial:

Overview — CESM Tutorial

I think your specific problem is related to the fact that you are using the namelist variable fgco2_file in your user_nl_datm file. That variable doesn't exist. For the historical case you've created, there should be a datm streams file in your CaseDocs directory called:

datm.streams.txt.co2tseries.20tr

Copy that to your case directory and prepend "user_" to the file name, e.g.,

cp CaseDocs/datm.streams.txt.co2tseries.20tr ./user_datm.streams.txt.co2tseries.20tr

and then change the file name as needed in user_datm.streams.txt.co2tseries.20tr.
Then run preview_namelists to see if you are pointing to your file.

Was everything I did before this operation correct? I still report the same mistake

After the create_newcase step, I would go directly to @oleson's instructions:

How to make the mode use downloaded CO2 data

./create_newcase --case HistClm50BgcCrop --res f09_g16 --compset IHistClm50BgcCrop --mach myintel --compiler intel --run-unsupported I created this case, I want the model to use my own file download of co2 (cmip6 download rcp2.6 data)...

Are you still referring to this error:

ERROR: Variable 'fgco2_file' from file '/home/hlh/clm5.0/cime/scripts/my_custom_co2_case/Buildconf/datmconf/namelist_infile' is not in the namelist definition.

Please attach your user_datm.streams.txt.co2tseries.20tr
