Dear teacher,
Sorry to bother you. I try to simulate GPP from 1980 to 2010 and the future GPP(SSP585) from 2020 to 2050 using CLM5-FATES to run compset I2000Clm50FatesGs and res f05_g16. Here is my confusion about the steps.
(1) First create a spin-up case (I2000Clm50Fates_spinup) to evaluate the model's equilibrium and change CLM_ACCELERATED_SPINUP=on, CLM_FORCE_COLDSTART=on.
The query I have is to carry on such an experiment do I require to Spin-up the model for over 600 years? Would it be sufficient to recycle 30 times form 1960 to 1979 for spinup in I2000Clm50FatesGs, then is it reasonable to use the 600-year spunup file as initial file to simulate GPP for 1980-2010(I2000)?
(2) Then create a common case (I2000Clm50Fates) running from 1980 to 2010, and set the finidat in user_nl_clm as the output of spin-up case.
Is this the right approach for simulating GPP from 1980 to 2010? The CLM-FATES model doesnot have IHISTClm50Ftates--compset, and the CO2 is constant. I wonder to know whether I need to change the amount of co2 to simulate the history GPP?
(3) When I try to simulate the future GPP(SSP585) from 2020 to 2050 using CLM5-FATES to run compset I2000Clm50FatesGs and res f05_g16, I am not sure how to choose the surfacedata, domain data, and finiidat.
So at first, I want to build a case ISSP585Clm using compset ISSP585Clm50BgcCrop, The ISSP585 compset would give domain, surface, and finidar data containing transient landcover, CO2, aerosol and nitrogen deposition, year-specific atmospheric forcing, etc. Then I want to use the inputdata from compset ISSP585ClmBgcCrop to compset I2000Clm50FatesGs to simulate the future GPP(SSP585).
Is it reasonale for I to use the inputdata from ISSP585ClmBgcCrop to run compset I2000Clm50FatesGs using CLM5-FATES model?
If it works, what should I pay attention to? If it doesnot, What should I do to simulate the future GPP?
Any suggestions will be appreciated! Thanks in advance.
