Re: ROMS output gradient calculation

You could try the XROMS Python package. It has a general function for calculating horizontal derivatives on the native ROMS grid, as well as specialized functions for calculating geostrophic surface velocity and horizontal buoyancy gradients. https://xroms.readthedocs.io/en/latest/calc.html ...

ROMS output gradient calculation

Dear All, Hope you are doing well. I wish to initiate again the geostrophic current issue for ocean ROMS community. I am trying to calculate it in Arabian Gulf with 1/120 degree resolution output. I am just curious how we can get gradient of pressure on skew curvilnear grid of ROMS output . My ...

Re: Calculation of Geostrophic Current

Hi Karsten, Hope you are doing well. I wish to initiate again the previous geostrophic current issue for ocean ROMS community. I am also try to calculate it in Arabian Gulf with 1/120 degree resolution output. I posted one actual problem regarding this on ROMS discussion recently. I just curious how ...

Calculation of Gradient on ROMS data

Hi All, I am doing some calculation to compute the geostrophic/thermal wind velocities but not able to get it correctly. I have the ROMS actual data on xi_rho and eta_rho grid. Can any one have idea how I can calculate it correctly? I need to calculate it on every vertical levels. For the ...
