[MITgcm-support] exf interp for smooth wind stress curl

[Menemenlis, Dimitris (3248)]

Chris and Matt, did issue below regarding bicubic exf_interp ever get resolved?

Is there a way to get smooth wind stress curl for hi-res integrations from coarse-res atmospheric forcing?

Basically the plot of the curl of wind velocity looks the same as the plot I sent you previously of wind-stress curl.  lThe problem appears not to be the bilinear interpolation of the buoyancy forcing terms; it appears that the bicubic interpolation of the wind velocity is not smooth enough to yield a smooth gradient.
