The Filtering mode of MetCal runs a 25-point smoothing box over the
entirety of the domain for the two or three dimensional variable
specified in the Identifier entry. The shape and weights of
the cells in the filter are shown graphically, and may be modified by
the user to smooth more heavily or lightly, as required. There is
no “magic number” up to which the cell-totals must add, so feel
free to modify the filter to fit your requirements. One of the drawbacks
of the MetCal interface distributed with version 1.7.1
of this distribution is that the output identifier is set equal
to the Identifier. This oversight will be corrected in
future versions of the interface.
