calculating ubar and vbar

Hi, I want to calculate ubar and vbar using u and v. Is it calculated using following formula, ubar = ubar + u*dz vbar = vbar + v*dz but in this case the units of the 2d vertical integrated momentum component will be m2/s (m/s * m) because we multiply with the thickness of the layer. In climatology ...

Re: REGRID - input gridded data does not contain model grid:

Okay, now it makes sense because, i interpolated wind components to u and v points. I will change my code and re try. I hop it will work in this time. Anyway, i think that this point is not clear in documentation but i will check it again. In ROMS forcing page sustr and svstr are in u and v points (...

Re: REGRID - input gridded data does not contain model grid:

I check the grid dimensions and they are same. May be i am little bit confused, so please tolerate me but i think that the error is expected when i use the lat-lon rather than x-y because lat-lon is in Lambert Conformal projection. See the attached plots that represent the grid points location (lowe...

Re: Compiling ROMS with ESMF

Hi, I think the problem is related with differences between versions of the ESMF. The coupling code is created with older version of ESMF. So, I apply following patch into Master/esmf_roms.F 552,553c552 < ! CALL ESMF_ArrayGet (romsGrdArray(igrid,ng), & < CALL ESMF_ArrayGet (romsGrdArray(igrid,ng),0,...
