About the component tides of the output file

#1 Unread post by tao »

Hello, everyone. I have a problem. I use AVERAGES DETIDE to obtain simulated tidal data. Now I generate roms_his and roms_har files, but I don't know how to obtain the amplitude and phase of each component tide :cry: . Is there any tool that can help me?
thanks for any suggest.

Hello. I've never used this module before, so I don't know what kind of variables are saved as output. But if the output file gives information enough, you can apply a simple harmonic analysis. Some good packages in Matlab and python were developed to make harmonic analyses and even predictions, and both use elevation time series. In MATLAB I always use t_tide package , and in PYTHON I've already used pytide routines. Additionally, there is a repository in Git Hub that was a more concise attempt to transcript t_tide script from Matlab to python, but it is still a work on progress.
