where can I get the spin up restart file of f09_g16

[dhj1986]

Dear everyone

I am trying to run the case B1850_f09_g16_CAM5, however, I cannot find any restart file for cesm1.2. The only one I find is "b.e11.B1850C5CN.f09_g16.005_yr402_cesm2_v4",

I have three questions for these files.

First, if I use this file, will there be any problem, since the restart files are created by a newer version model?
Second, does the pre industrial case reach spin up at 402th year?
Third, is there any website, from which I can get the restart file (spin up) for the case B1850_f09_g16_CAM5 or B1850_f09_g16_CAM5_CN.

Thanks for your help.

Best wishes.

For some general advice about spinup of model simulations see this

is this case (b.e11.B1850C5CN.f19_g16.0850cntl.001) nearly spin up

I found a case b.e11.B1850C5CN.f19_g16.0850cntl.001 in the ccsm4_init, where the restart file at 850th year is offered. I am wondering whether I can call the case nearly reach the spin up at 850th year, or I still need to integrate for some time. Best wishes. Haijin

For your first point I would compare the versions between the restart version and the model version you are going to run with in terms of things that significantly change answers. If the differences aren't significant it likely won't matter. For the second see the above discussion it all depends on what you are trying to do. The only website is the experiment database. Not everything is saved so you can't necessarily find something that matches everything you want.
