which compset is used for the control and climatology run on cesm1_2_0

[yaozhixiong@foxmail_com]

Hi,I am going to run the climatology and control run of the atmosphere, ocean and coupled model on cesm1_2_0. The compsets are showd below, is it right? How to choose a proper compset?  Or how to know whether a compset is suitable for climatology or control run? My major is physical oceanogolophy, so I don not concern the biology and chemistry part.                         climatology run             control runatmosphere            F                              FAMIPocean                        C                             CECOcoupled                  B                              B1850 Thank you very much.Best regards,yao zhixiong

I am not sure I understand what you refer to when you say climatology and control run."Or how to know whether a compset is suitable for climatology or control run?"Please could you clarify ? FAMIP compset uses active atmosphere and land models with prescribed SSTs and sea-ice coverage. In this comspet, the datset (SSTs, greenhouse gases, etc) are varying from year to year.
B1850 compset uses active atmosphere, land, ocean and sea-ice model. The compset uses cyclical compset (1-year cycle) typically of pre-industrail condition,

We can see that the time period of "volc" is 1850-2008, "solar" 1610-2007, "ggas"  1765-2005. I think these are varying from year to year. But the "sst" data is a climatology data. It is 1-year cycle. I don't know how to choose a compset. For example, now I want to run the control run of the ocean model on CESM1_2_0, which compset should I use? And which compset should be used for the cliamotology and control on other models(e.g. atomosphere and coupled model)?

If you use the compset FAMIP, the sst should vary year to year.If you created a new case with:-compset FAMIP -res f09_f09The default SSTs will vary year to year. The default SST dataset is:   /glade/p/cesmdata/cseg/inputdata/atm/cam/sst/sst_HadOIBl_bc_0.9x1.25_1850_2012_c130411.nc

=========To answer your question "which compset should I use ?"
You need to review each compset to see if it fits your need. For instance, you could use:If you want cyclical dataset, you can use:Atmosphere: F1850 (for pre industrial) or F2000 (for present day)
Coupled: B1850 (for pre industrial) If you want year-to-year varying dataset:Atmosphere: FAMIP
Coupled:B_1850-2000_CN

For the ocean model, CECO will use cyclic year 2000 forcing and will also turn on BGC (biogeochemistry). You say "My major is physical oceanogolophy, so I don not concern the biology and chemistry part" so I would use the C compset for your control run instead. To have datasets vary from year to year, use the CIAF compset (IAF stands for inter-annual forcing, the dataset contains 62 years of data: 1948 - 2009).

Thank you very much. Sorry, I made a mistake. The compset FAMIP which I run before was in CCSM4 , not in CESM1_2_0. There are two different sst datasets when I run the compset FAMIP in CCSM4 and CESM1_2_0.CCSM4  ----  atm/cam/sst/sst_HadOIBl_bc_0.9x1.25_clim_pi_c100127.ncCESM1_2_0  ----  atm/cam/sst/sst_HadOIBl_bc_1.9x2.5_1850_2012_c130411.ncMaybe it is a problem about the different versions.

The correct SST for an AMIP run is:
atm/cam/sst/sst_HadOIBl_bc_1.9x2.5_1850_2012_c130411.ncI think FAMIP was not a supported compset for ccsm4. (I believe the commonly used AMIP compset was FAMIP_CN).Also,  you always need to check your simualtion is scientifically supported. http://www2.cesm.ucar.edu/models/scientifically-supported
