Hello, guys!

I'm really noob with the model and i'm stuck reading about how to set up the boundary condintions for 2D Field (10 S levels) of salinity and temperature for my model in the Cantabric Sea. By the time I succeded ran the model with "BULK" and "no BULK" atmospheric information in order to force the ocean surface and set up the boundary conditions of barotropic velocities and sea level. My objective now is to fix the problem with the salt/temp boundary information and then to set up a nudge condition to make more robust the model due to be used as operational system.

my *.h (upwelling) conditions setting:

** Input script: ocean_upwelling.in

I'm sure i'm setting something worng, but i didn't found the answer in all the post i read. Any help??
Thank you all for your time!

First of all, this must be from an ancient version of ROMS. Why are you not using the newest ROMS?

Second, this code is commenting out the M3 and T radiation boundary conditions. The TNUDGING is just a modifier on the radiation condition.

I'm ussing roms 3.5 but it's possible that *.h and *.in script was an old modified script from other version. I'm not prety sure about versions of ROMS beacouse it's my first time ussing ROMS (in fact i started with this model one month ago) so i don't known the "scene" at all. The reasson for use that version is that the system is an upgrade for another simple model (without heat, temp and salt) built up with that version, so at least i'll have to try with that version and if have time i'll have a go to the newest one.

I can't manage to read the salt and temp variables in my BRY setting the TRADIATON lateral conditions for my WEST and NOTH boundaries.
¿¿Maybe Am I missing something related with the boundaries in the *.in file??

I've read some info in other posts about declaration of lateral boundaries conditions in the *.in file but in mine's this block of code doesn't exist. So I'm stucked setting the boundaries in the *.h for salt and temp. (If you need some specific information for make a diagnosis please let me known)

Thank you Kate! Wonderfull ACTIVE forum, congratulations for all of you!

You need to have both TRADIATION and TNUDGING - it's the combination that we are using.
