Table 4.15
Type of spatial processing used to arrive at a given data value from the source data
Notes: (1) This method assumes that each field really represents box averages/maxima/minima where each box extends halfway to its neighboring grid point in each direction to represent averages/maxima/minima of values from the source grid with no interpolation.
(2) Budget interpolation means a low-order interpolation method that quasi-conserves are a averages. It would be appropriate for interpolating budget fields such as precipitation. This method assumes that ithe field really represents box averages/maxima/minima where each box extends halfway to its neighboring grid point in each direction. The method actually averages bilinearly interpolated values in a square array of points distributed within each output grid box.
(3) Performs a budget interpolation at the grid point nearest to the nominal grid point.
