Re: Tidal Forcing File

Giannis, Another thing you might want to look at are your barotropic boundary conditions. If you are using ADD_FSOBC & ADD_U2OBC as well as SSH_TIDES/UV_TIDES, and if the regional model you are downscaling from is not de-tied (i.e. it has tides) you might be giving ROMS the tidal forcing twice, whic...

Re: DSTART, TIDE_START & TIME_REF in the *.in file

Hello, The way I understand it is: dstart = time_start - time_ref tide_start = tide_base_date - time_start Where time_ref='19960101', time_start='19960501' and tide_base_date is the base date you used when generating the tide forcing file. Basically if your tide base date pre-dates your initializati...

Re: Lagrangian floats problem/question

Hello, I am having issues trying to use the lagrangian floats implemented in ROMS. I compiled ROMS using svn version 655 with #define FLAOTS. My input file looks like this: Lfloats == T ! Switch to control the printing of floats positions to standard output ! file, [1:Ngrids]. ! Fprint == T ! Flag i...

Re: Tidal forcing at the open boundary

Ok, I see your point it would be ideal for me to test both ways. I don't have any experience filtering the tides and from what I have read so far it doesn't seem trivial. Do you have any material that may be helpful, or could you point me in the right direction? Any suggestion is welcome and thanks ...

Re: Tidal forcing at the open boundary

Thanks for the reply Kate, Boundary conditions from NCOM are given every 3 hours and I would say tides are really good (they also assimilate altimetry) but I can't say if better than TPXO, probably not. So it would probably be better if I provide tide currents from OTPS or adcirc and filter tide sig...

Re: Tidal forcing at the open boundary

Quick question, I want to set up an operational system simulating full ocean physics in the Caribbean, meaning I want to simulate tides along with wind induced currents and so on. I am providing tidal forcing (tidal ssh and tidal induced currents) at the open boundaries via a netcdf tide forcing fil...

Re: Plot velocity vectors

Try putting a dot before the multiplication in {sqrt(-1)*v} So it should look like {sqrt(-1).*v} I think the reason dimensions do not agree is because you are doing a matrix multiplication of a single value and a matrix instead of an element-wise (or point-wise) multiplication of the matrix with the...

Re: Model blowing up

gloeg002: I have roughly 1 year of experience with ROMS but I'm pretty sure your problem is with your vertical grid. As you can see the model is blowing up at your first level (111 , 96, 01) , but more importantly your maximum grid stiffness ratios are off the roof! This is specially important if yo...

Re: Extreme zeta values and OBC

I had a similar problem in a real application. I would suggest as Kate mentioned to provide boundary values (including zeta), the better the temporal update on the values the better solution you may get. What I do in my model is extract initial and boundary values at 3hr intervals from a coarser val...

Re: Question about roms_tool?

Safoora, etopo2 is a 2min Global bathymetry by ngdc, WOAXXXX and COADS are the World Global Atlas and the Comprehensive Ocean Atmospheric Data Set, both global. These two are good for basin scale resolution or lower. If you are working with regional models closer to shore with resolutions higher tha...

Re: Doubts about Seagrid

I have never tried to load two coastlines at the same time in Seagrid, but I do know that coastline files are just a longitude, latitude pair where coastline segments are separated by Nans. So I would just try to separate file 1 and 2 by a pair of Nans so that Seagrid knows these are separated coast...

Re: Error encountered in compiling jobcomp using Romstools

Hi Jerry, I got this same error a couple of weeks ago using ROMS AGRIF version. You error is most probably because you are not giving the correct path for the netcdf libraries. Make sure your netcdf libraries are set correctly in your jobcomp script. From waht you posted my guess is your netcdf incl...
