Ocean Modeling Discussion

I was running a 4DVAR experiment using a single observation on the North-Western Mediterranean sea to better observe the effect of one variable on another. For the difference between analysis and background, I noticed a lot of noisy patches, principally at the boundaries, gradually increasing as we ...

Thank you for you reply. In the roms.h I have: #ifdef NLM_DRIVER # define AVERAGES /* define if writing out time-averaged data */ #endif even if I did not find any NLM_DRIVER flag in cppdefs.h. However, I have also export MY_CPP_FLAGS="${MY_CPP_FLAGS} -DAVERAGES" in the build_roms.sh. The tricky ...

Dear users, I am running a RBL4DVAR experiment and I need to save hourly-average output for the u and v velocity components from the nonlinear run in daily files. The assimilation window is 3 days, from 2020-09-29 00:00:00 to 2020-10-01 23:59:60. Here they are the parameters of the sim: ! Time ...

Hello, I am using the new roms_metrics.m function (track_ticket #879). I noticed it gives different x_rho and y_rho variables (x_psi,...) with respect to previous tools, only concerning the first (1) and last grid points (Lp and Mp). They indeed result to be dx/2 and dy/2 spaced with respect to the ...

Dear all, I am running a nested grids configuration with two nesting levels (ONE-WAY) and the model works fine without floats. I would like to know if it is possible to add floats so they can move from a grid to another and vice-versa (in order that they are alternatively subjected to different flow ...

Dear all, I write to ask for a problem arose using the check_refine function to control the consistency between parent and child grid. It is not so crucial since it is a tool to check, instead of produce necessary files to run the model, but I am not sure a similar problem may arise somewhere else ...
