tide-calibration

#1 Unread post by AMIRHOSSEIN »

Hi,
I used romstools for creating grid and tide and run the model

finally, I checked the zeta parameter in .his file but the results of the zeta were not in the desired range(should be somehow -1.5<zeta<+1.5 near the shore)

how can I prepare the zeta parameter?

Amir,

I looked at your log file and nothing jumped out at me.
While you are testing tides no need for 20 levels. You can speed things up that way.
Maybe try setting up a stations file. One of your stations could be near the mouth, say at 26.35N,55.7N.
You have to tell ROMS what the stations file name is. You need a line something like:
SPOSNAM = /home/Amir/Projects/Gulf/DATA/sta_Gulf.in
Also ensure LSTATIONS == T
...and the station outputs what you want
You can have as many stations as you like (I suggest one for each station where you have data or harmonics to compare)
The output file is also netcdf but is very simple so if that gui you are using to look at the data doesn't handle stations files,
you should be able to open it easily with python or matlab or whatever. You will need something more than the gui anyway, for checking
your harmonics or (for that matter) doing any serious science with ROMS outputs.
For two stations there would be something like:

NSTATION == 2

POS = GRID FLAG X-POS Y-POS COMMENT

1 1 53.8100 24.2637 !1 Near mouth
1 1 49.0000 29.7200 !2 Basra end

Good luck

John
