Re: ROMS I4DVAR first cycle fwd0 looks very different to first cycle VERIFICATION, with seemingly identical inputs
Hernan et al., I have been applying a sponge layer via the recommended approach of writing the nondimentional spatial distribution arrays "visc_factor(i,j)" and "diff_factor(i,j)" into the grid NetCDF file. This works fine for the NLM_DRIVER and VERIFICATION runs, however I have found that for the ...

ROMS I4DVAR first cycle fwd0 looks very different to first cycle VERIFICATION, with seemingly identical inputs
Hello, I have been having various issues with a ROMS I4DVAR configuration. The configuration is for a recent 5 month period, but is based on previous configurations that worked well. I have run a 5-month VERIFICATION run and all looks good and as expected. When I run the very first cycle of the ...

Re: /usr/bin/env: perl^M: No such file or directory
Ahh OK thank you. I did this as the Gui was so much easier, then I copied to the Linux machine. Which I now realise is incorrect. I have now downloaded the code from the terminal and checked out the required version, and all is compiling well. Thank you. git clone https://www.myroms.org/git/src ...

Re: Obs file altered in VERIFICATION run such that Zgrid is wrong, then observations rejected
The Zgrid values in my obs file are all between 1-50 where nlayers=50, and the depth values are all 0 or less (0 or negative). From the ROMS code I cannot see how it is then possible that the Zgrid values in the obs file are being overwritten. When I have run similar VERIFICATION runs in the past ...

Re: Obs file altered in VERIFICATION run such that Zgrid is wrong, then observations rejected
Thank you for your help. I have double and tripled checked and I believe my Zgrid and depth values are correct. Yet the observations are still being rejected. Is there a way I can find out why ROMS is rejecting the obs? I see that they are rejected in the log file but cannot figure out why. They are ...

Obs file altered in VERIFICATION run such that Zgrid is wrong, then observations rejected
Hello, I am seeing some unusual behaviour with Zgrid when running VERIFICATION. When I kick off the VERIFICATION run, the input observation file is altered. It then has incorrect Zgrid, so the observations are rejected and hence incorrect values are output to the mod file (NLmodel_value output in ...

Re: /usr/bin/ld: cannot find -lnetcdff
Thank you.
I did not know that I had to install the Fortran netCDF library and the netCDF C library separately.
I installed netcdf-fortran and now I have netcdf.mod, typesizes.mod and libnetcdff.so as you said, and can compile ROMS!
Thanks so much for your help.
