Eddies detected on land about py-eddy-tracker

[Fanny-Chenillat]

Thanks Antoine for your question that gave me a clue: it was actually necessary to mask the data (zeta in this case).

So I replaced the 0's with nan's at the land point from sea surface level (zeta=np.where(mask_rho==0,np.nan,zeta in the locally modified eddy_identification function), and that was it: no more eddies on the Balearic islands!

Cheers!

Island are masked by nan or by a mask?

Island are masked by nan or by a mask?

For the model, there is a gridfile where island are masked by a mask, but values are typically 0 on island for the dataset of surface sea level. There is also a mask on the datafile and it seems that it is not correct (it is nan everywhere). Does pyeddytracker used the mask on the datafile? Or should I directly mask the data on the ncfile?

I double-checked for the AVISO data where values are masked by NaN.

Best regards

Fanny

could share one croco file which produce detection over land, and how you run this detection?

Would you mind if I send you documents by email?

You're welcome, I didn't do anything
