the simulation shows results on land and not on sea

[Parag0206]

The simulation produces results(all fields like SST,SSS,etc.) on land and not on the sea.

This maybe due to improper mask

[Parag0206]

Yes, the msks were the problem, the land and ocean masks both were swapped. But, after correcting, still the error persists

[Parag0206]

The topo file generation method is not the reason of the problem(whether topog file is generated from ETOPO or GEBCO does not matter).

[Parag0206]

further the ocean domain shows that all values are missing

[nmathewa]

• Topog is correct but the mask file is incorrect
• The depth should be positive not negative
• mask it accordingly

[nmathewa]

bath = etopo.depth.values

n_bath = -1*(np.where(bath > 0,0,bath))

Take a look, values greater than 0 will be 0 and less than zero will be multplied by -1

[nmathewa]

• Can you share the topo file for the specific problem (I also have to check which script I used) @Parag0206
• I will try to organize the codes as possible

[Parag0206]

As mentioned above, the problem is that the ocean values for bathymetry are below 0(sign convention). Convert them to positive as mentioned here

bath = etopo.depth.values

n_bath = -1*(np.where(bath > 0,0,bath))

Take a look, values greater than 0 will be 0 and less than zero will be multplied by -1

or use cdo expr to solve this
