Help for running CAM5-MAM7 with external forcing in SERIAL mode

Hi everyone I have a problem when I try to running the  FSTRATMAM7 in cesm1_2_2. I was doing some test runs and everything worked fine, until I changed ext-frc type to SERIAL mode and the model failed.
Particularly, with the files of ext_frc and surf emiss default the model finishes well when it runs in CYCLICAL mode, but now I have tried changing it to SERIAL mode and it does not work.
The default files for MAM7 are for the year 2000 so I have tried a run starting on 2000-03-15, since I understand that in SERIAL mode the model seeks to extrapolate forward and back, a simple run of 5 days does not work and I get the following message: QNEG3 from chemistry/H2SO4:m=131 lat/lchnk=    360 Min. mixing ratio violated at    5 points.  Reset to  1.0E-36 Worst =-1.1E-12 at i,k=  11 28

I have also read Guide to debugging WACCM runsbut in my bld directory I did'nt found a core.XXX file for run the gdb command. I really aprecciate a help with this, since I am very stuck and I can not continue.
Thanks!

Hi Adriana,the problem seems to be that you are using emission files that are designed to work for cyclical configurations only. Setting the model to serial requires emissions that cover the period you are planning to run. If you want to start Jan 1st, you need emission files available for that or an earlier date (so at least Jan 1st of that  year). Same for the end date of the simulation.Simone

Hi Simone thank you very much for your reply.

So that's mean that if I want to run just 5 days I will need a file with daily emissions really?

I wonder if I make a simulation for one months satarting 15st of February for example should work? Since the default files are monthluy.

Thanks

If you want to run a certain period, you need to make sure that your emissions cover that period. You can start your run at Jan 15 until Nov 15. If you expand your emissions to Jan 1st, than you can start on Jan 1st, please let me know if this does not make sense.

Tahnk you very much for your answer. Yes you are right the model works when I start from 15 of Jan. I realize that this problem occurs due to the MERRA data files when I included them in the user_nl_cam I obteined this error. I was using the FSTRATMAM7 compset ( 2000_CAM5%SMA7_CLM40%CN_CICE%PRES_DOCN%DOM_RTM_SGLC_SWAV)and then I thought that maybe the problem is due to the compset and I create a new compset (with success) where I change 2000 by GEOS like this: GEOS_CAM5%SMA7_CLM40%CN_CICE%PRES_DOCN%DOM_RTM_SGLC_SWABut I also get the same error and I dont know where I can see my problem because the cesm.log always say the same.nspec=           3

                                                                                                    It is possible that MAM7 have problems with nudging files??? How I can look more specifically the problem?
I really appreciate any help!
