The old regrid2() (user defined) function is only available with grads 1.x.
For grads 2.x your options for regridding includes the bi-linear
interpolation function lterp(), and re()/regrid2() in opengrads. The
regridding functions re()/regrid2() are more capable than lterp(), as they
include several interpolation/remapping options. See:

For examples, look at the cookbook:

This can also be accomplished with lats4d:
