HYCOM data serve as initial and boundary conditions

#1 Unread post by Arvin_Yin »

Hi everydody. I want to use HYCOM data to generate my own initial and boundary condition files. But I am very confused about the interpolation.

I used the RNT toolbox before. First I fill the HYCOM data use linear interpolation, then use rnt_2Doa to interpolate HYCOM data to ROMS grid, at last do the vertical interpolation. To be honest, the result was not good enough.

Unfortunately, when I updated my matlab to version 2013a, the RNT toolbox could not work anymore. So I want to try a new interpolation way now. Is it OK if I simply use matlab interp2 function instead of rnt_2Doa?
Anyone help?
Thanks a lot!

We have some Python tools for doing this, dependent on pyroms.

Thank you, kate! You are so kind. I searched "pyroms" and found this link
https://github.com/kshedstrom/pyroms
Is it right? I have never use Python before, but now I couldn't wait to learn it.

Yes, that's right. I just pushed out a new example with the HYCOM files in it.
