Re: How could I get the corresponding latitude at each longitude for a chosen value's contour?

You can use linint2_Wrap.

Going to higher resolution does not add any additional information.

I don't think you can get the lat/lon of a contour line.

Peraps, at each longitude, you could find the
index values which straddle 5880; then interpolate
to find the estimated latitude of the 5880 line.

Good luck
