Ocean Modeling Discussion

Hello,

I want to have a look at into the nesting grid files for the realistic nesting case "US East Coast", but I can't find the links of the files on ROMS website. Maybe I missed something although I tried best to search.
Could anybody please help me on this?
Thanks in advance.

Sorry, Arango. I think I must misunderstood something about the parallel I/O options and missed some information about the release news. Hope this feature can be ready to test.

Thank you anyway, and sorry for bothering everyone here.

Any body/help here?

Hello, I compiled ROMS 564 with PGI fortran and netcdf4.4.1, and tried to active CPP definition HDF5 and PARALLEL_IO. The compilation is ok, but when I ran the executable by 6 CPUs, I got error message: ERROR: Abnormal termination: NetCDF OUTPUT. REASON: Parallel operation on file opened for non-par...

I didn't try to restart it yet, I'll do that ASAP and post the result here. I didn't define PERFECT_RESTART in either case. I applied NtileI,NtileJ = 8 and 16, total is 128 processors. The output result looks reasonable. If PERFECT_RESTART can explain the file size of ocean_rst.nc, can it explain th...

Although NetCDF4/PARALLEL_IO has been available for a long time, I just finished the compilation recently. And now I still have some problems when I ran it. I took the UPWELLING case as the test, and I compiled it to two versions. One was compiled with NetCDF4/HDF5 libraries by turn on PARALLEL_IO, ...

Hello Kate, Thank you. I just realize maybe I misunderstood the poster https://www.myroms.org/forum/viewtopic.php?f=17&t=1802&start=0 and made a mistake by changing nf90_clobber to nf90_noclobber. I am very sorry about this. But I am really cofused about LDEFOUT. Seems no matter True or Fals...

Hello, I tried to restart ROMS from an existed rst file, but ROMS just quit the job with such kind of message: NETCDF_CREATE - unable to create output NetCDF file: /output/ocean_his_0003.nc call from: def_his.F DEF_HIS - unable to create history NetCDF file: /output/ocean_his_0003.nc Actually, befor...

Hello, I learned that ROMS do the parallel IO with NETCDF4 and HDF5, but for some reason I don't have them in hand so far. So I want to know if ROMS can do the parallel IO with pnetcdf? If ROMS can do this, how do I modify makefile and *.mk? And, does it need HDF5? Any help will be appreciated. M.

I think they are the same. When you set the value of dqdt in "ana_sst.h", you need to divide it by (rho0*Cp), and then the unit of dqdt is m/s. Do I need to divide dQdSST by (rho0*Cp) when I am preparing the forcing file? In the varinfo.dat: 'dQdSST' ! Input 'surface net heat flux sensiti...

Thanks a lot Kate.

What if I want to relax the model SST to another SST dataset which has finer resolution than Tair?
From ROMS cppdefs I can only find QCORRECTION to do it. Is there any other way to do this like SCORRECTION
or SRELAXATION?

Hello, Is dqdt in set_vbc.F same as dQdSST in forcing file? stflx(i,j,itemp)=stflx(i,j,itemp)+ & & dqdt(i,j)*(t(i,j,N(ng),nrhs,itemp)-sst(i,j)) If so, the unit of stflx is "degC m/s", while the unit of dQdSST is "Watts meter-2 Celsius-1". It seems the units of both sides ...

Are you using BULK_FLUXES? If so, it is already computing a sort of nudging to SST via the computation of the heat fluxes as a function of SST . The justification for nudging to SSS is that there is no feedback to SSS in the bulk flux routine. Hi, Kate, Do you mean BULK_FLUXES has the nudging to SS...

Thanks very much, Kate.

Hello everyone,
Is there any possible I can find an older version of ROMS?
The revision I want is 58.
Thanks!

thank you very much!

something like this? cc -O -I/usr/local/include -c -o binio.o binio.c cpp -P -I/usr/local/include <blkdat> blkdat.f ifort -c -fast -O3 -align -free blkdat.f cpp -P -I/usr/local/include <curv_to_cart> curv_to_cart.f cpp -P -I/usr/local/include <roms_v5d> roms_v5d.f ifort -c -fast -O3 -align -free rom...

another question:

Do I need ncargf90 or NCARG?

Hi roms-idemoc, I am a beginner of ROMS and Vis5d, and I encountered some problems on compiling roms_to_v5d. Here is the compiling environment: system: RedHat Enterprise Linux, 64-bit compiler: ifort netcdf version: 3.6.1 It seems something wrong with compiling options such like "-lnetcdf"...

new results: In perfect_restart case, the restart file was created, but no variable was written into it. I also compared my .h file with upwelling, and I put following scripts into my .h file: #ifdef PERFECT_RESTART # undef AVERAGES # undef DIAGNOSTICS_BIO # undef DIAGNOSTICS_TS # undef DIAGNOSTICS_...

> 1) does your app work ok without perfect restart ? (so does it work ok with just the normal restart) yes, it works without perfect restart. > 2) did anything get written to the restart file? was a restart file actually created? yes, restart file was created, and had something in it. > 3) the creat...

PERFECT_RESTART option works well in upwelling case.
What does this indicate to my case?

Thank you for replying me so quickly! I used 28 processors, and defined NRST=60 to make ROMS write rst file at 60th time steps. Here are the output informations: Model Input Parameters: ROMS/TOMS version 3.0 Operating system : Linux CPU/hardware : x86_64 Compiler system : ifort Compiler command : /u...

Hi,

When I define PERFECT_RESTART option in my .h file, ROMS will get a exit-signal to end the all processes, without any blowing up. I use the GLS_MIXING scheme in my test.

Is there anybody who can give me some advices? thanks!
