Getting NaN Values

[Former user]

Hi,

I have created a simple code to generate a tidal time series at one particular location near the Canarian Islands and I am getting all nan values. It happens in other location but it does not happen in a point next to Maldives.

Thanks in advance,

Angel amores.

If the grid data is undefined, the function returns NaN. Try to download the HR grids from the AVISO site.
