Problem in creating surface dataset for RCP scenarios in CLM5 (CESM2.1.0)

[umair@skku_edu]

Hy all,

I am trying to create a surface dataset for SSP-RCP scenarios for a regional case. I have followed the steps 1.6.3. Running Single Point Configurations — clmdoc release-clm5.0.01 documentation from the user manual.
Step 1: Creation of grid file (Successful).
Step 2: ./mkmapdata.sh -f $GRIDFILE -r $PTNAME -t regional --> map data creation (successful)
Step 3: ./mksurfdata.pl -r usrspec -usr_gname $PTNAME -usr_gdate $CDATE -y "1850-2000" --> surface data creation for historical data and dynpft (successful)
Step 4: ./mksurfdata.pl -r usrspec -usr_gname $PTNAME -usr_gdate $CDATE -ssp_rcp "SSP2-4.5" --> (gives error)
** Invalid ssp_rcp: SSP2-4.5

Step 4 shows the RCP scenarios data creation and cannot be run, might be due to wrong -ssp_rcp name. Can you please suggest me what are the right Scenario names to make the surface date.

From the help, It shows that:
-ssp_rcp "scenario-name" Shared Socioeconomic Pathway and Representative Concentration Pathway Scenario name(s).
"hist" for historical, otherwise in form of SSPn-m.m where n is the SSP number
and m.m is the radiative forcing in W/m^2 at the peak or 2100.

I followed the above pattern, but it didn't work.

I would be very grateful for any positive feedback on this.

Thanks

This is something that was fixed in later versions of release-clm5.0. If you update to the very latest release version release-clm5.0.30 you won't see this problem.

Here's information on the problem:

mksurfdata.pl aborts with "** Invalid ssp_rcp:" for default and explicit ssp_rcp argument. Quotation marks interfere in is_valid_value() function · Issue #672 · ESCOMP/CTSM

Thank you so much for your prompt reply. It worked by adding (noquotes=>1) and changing "ssp-rcp" to "ssp_rcp" in line 534 of mksurfdata.pl.

Thanks

I have one more question related to this.

./mksurfdata.pl -r usrspec -usr_gname $PTNAME -usr_gdate $CDATE -ssp_rcp "SSP2-4.5" -y "2000-2100"

This step works fine now, by following the above link.
But the problem is, even I am giving "SSP2-4.5", the landuse_timeseries_SSP2-4.5_16pfts_Irrig_CMIP6_simyr2000-2100.txt file generates all the link for SSP5-8.5.

I think it is generating for a by-default option and may be not accepting the command line option of -ssp_rcp. I tried to search in /home/cesm/cesm2.1.0/components/clm/bld/namelist_files (namelist_definition_clm4_5.xml and namelist_defaults_clm4_5.xml) files, but could find any default value related to SSP5-8.5.

Can you please give your thoughts on this issue.

Thanks

Also find the attached mksurfdata.pl file.
