The problem is that the IDV does not handle derived quantities that
involve derivatives when the domain of the grid is straight lat/lon.
This is listed in the known bugs, but probably not as evident as
what your problem is.  With lat/lon grids, we need to account for the
decreasing spacing of longitude lines with increasing latitude.
