./namelists/default/schemes.nl. This means that two Kalman Filter schemes can be defined but
with different values for its ratio parameter. The schemes have been grouped into the components defined in
 Components. As an example,
scroll down to the Downscaler section in ./namelists/default/schemes.nl:
# Downscaler
dNearest     class=DownscalerNeighbourhood neighbourhoods=n1
dDist16      class=DownscalerNeighbourhood neighbourhoods=n16 weightOrder=2
n1           class=NeighbourhoodNearest num=1
n16          class=NeighbourhoodNearest num=16
   Here two downscaling schemes have been set up. First, the nearest neighbour scheme has been defined, and
   given the name dNearest. Configurations wishing to use this schemes would use this name to
   refer to it. This scheme uses the neighbourhood scheme called n1, which is
   also defined in the schemes namelist. The dDist16 scheme weights the 16 nearest
   neighbours by the inverse square distance that the points are away.
To add a scheme, look up the class name in Components and fill in any of the options.
The naming convention is to start all selectors with the letter 's', downscalers with 'd', neighbourhoods with 'n', and correctors with 'c'. More conventions may be added later.
