Some preprocessing and postprocessing characteristics of the Eta model are shown. The preprocessing routines (version 1989) seem to be inadequate if the model runs in polar regions and thus the horizontal interpolation procedure must be checked very carefully in these cases. New preprocessing routines have been developed and an application of a new horizontal interpolation is shown. New postprocessing routines, based on an operational version of the Eta model, are also implemented.
