Hi,
I am trying to run my land-only simulations forced with atmospheric data from SSP-RCP scenarios using CLM5. I understand there are some previous threads; however, I still have a few questions after reading these threads. On my side, I want to simulate GPP and crop yield changes from 2025 to 2100, and I am using the GSWP3V1 forcing dataset. This is my understanding below:
a. Identify the anomaly forcing data on derecho: p/cesmdata/cseg/inputdata/atm/datm7/anomaly_forcing/xxx
Identify the driver on derecho: nuopc
b. Create a new case: ./create_newcase --case ~/XXX/XXX --res CLM_USRDAT --compset SSP370_DATM%GSWP3v1_CLM50%BGC-CROP_SICE_SOCN_MOSART_SGLC_SWAV --project UIUC0025 --run-unsupported
c. Revised env_run.xml:
<entry id="DATM_CLMNCEP_YR_ALIGN" value="2000">
<entry id="DATM_CLMNCEP_YR_START" value="2000">
<entry id="DATM_CLMNCEP_YR_END" value="2014">
<entry id="RUN_STARTDATE" value="2025-01-01">
<entry id="STOP_OPTION" value="nyears">
<entry id="STOP_N" value="76">
<entry id="HIST_OPTION" value="nyears">
<entry id="HIST_N" value="1">
d. Revised user_nl_datm:
anomaly_forcing = 'Anomaly.Forcing.Precip','Anomaly.Forcing.Temperature','Anomaly.Forcing.Pressure','Anomaly.Forcing.Humidity','Anomaly.Forcing.Uwind','Anomaly.Forcing.Vwind','Anomaly.Forcing.Shortwave','Anomaly.Forcing.Longwave'
As stated, I wrote all the steps I knew. (1) Could anyone please help me check if I consider all the stuff? In addition, for step d (Revised user_nl_datm), although I followed the instructions in 1.5.9. Running with anomaly forcing — ctsm CTSM master documentation, I am not sure if it is right. (2) Could anyone please show me a SSP example that contains the content in the user_nl_datm? I'd like to look at what it is.
Thanks!
