Possible Issue with Longitude Data in ocean_tide NetCDF Files (FES2022b)

[ruby-vallarino]

Hello everyone,

I’m currently working with CoastSat - Tidal Correction, in particular with the NetCDF files provided in the ocean_tide folder (FES2022b), and I’ve encountered an issue with the longitude data that seems to be incorrect.

Upon inspecting the files, I noticed that the longitude (lon) variable has invalid values. Specifically, the valid_min and valid_max attributes are both set to 0.0, which is not typical for longitude data. Additionally, the longitude array itself seems to be filled with either 0s or _FillValues (e.g., 1.84467440737096e+19), indicating missing or invalid data.

But when I run the CoastSat - Tidal Correction code for tidal time series, it only provides tidal data for the eastern coast of Australia. However, I’ve tried several other locations, such as the Pacific coast of the Americas and the coast of Portugal, but no tidal data is generated for these areas.

Has anyone else encountered this issue with the longitude data? Is there a fix or workaround available for this, or could this be an issue with the dataset itself?

Any advice or insights would be greatly appreciated!

Thanks in advance for your help.
