11! This routine interpolates gridded data, Finp, to model locations !
12! Xout and Yout. Input data are allow to have longitudes ranging !
13! from [-180 180] or [0 360]. Usually, the ROMS application have !
14! longitudes in the range [-180 180]. !
15! !
16! The Imin, Imax, Jmin, and Jmax indices are the global values of !
17! application domain in serial I/O. However, in parallel I/O they !
18! are the tiled values. !
