boundary file

[pooran]

Dear friends
i faced with open boundaries for first time. My domain has 3 open boundaries (east,west and north) and one closed (south). I think that it needs T,S,U,v and zeta data for each boundary. i become grateful if you help me:
1- would you please introduced the best way (especially Matlab routines) for creating boundary files.
2-should it need separate boundary files for each open boundary?
3-should boundary file include data along boundary line or in vertical plane? For example if we have “l” layers and there is “m*n” cells in each boundary , so each boundary file should have data m*n*l dimensions?
Many thanks for your time and attention
cheers

There are two examples of the boundary file structure in Data/ROMS/CDL. All can go in one file. For momentum, you can specify say both:

Code: Select all

	float vbar_west(bry_time, eta_v) ;
		vbar_west:long_name = "2D v-momentum western boundary condition" ;
		vbar_west:units = "meter second-1" ;
		vbar_west:time = "bry_time" ;

and

Code: Select all

	float v_west(bry_time, s_rho, eta_v) ;
		v_west:long_name = "3D v-momentum western boundary condition" ;
		v_west:units = "meter second-1" ;
		v_west:time = "bry_time" ;

For the matlab, have you downloaded the matlab tools from myroms.org? I expect there's something in there for making boundary files since most of us have to do it.
