#  Data prep of the NDAS Guess for the SREF
#  Programmer: Jun Du
#  Date:       04/25/2001
#  Change log --
#  11/14/2001: Jun Du  modified for Nam 12km version
#  05/17/2002: Jun Du  input global data changed from 
#                      T170-specific to more general format
#  10/16/2003: Jun Du  (1) resulted ndas resolution was changed 
#                      from 48kmL45 to 32kmL60; (2) ndas truncation
#                      source code was updated to include new
#                      cloud fields and skin-T adjustment due to 
#                      topo difference etc.. (Thanks to Hui-Ya 
#                      and Eric!).
#  04/18/2005: Jun Du  modified to be T382-compliant
#  07/19/2005: Jun Du  change SST data from NESDIS 50km SST analysis to 
#                      the Real-time Global SST analysis
#  03/22/2006: Jun Du  add two off-time cycles (03z and 15z)
#  06/01/2006: Jun Du  switch from Eta-based ndas to NMM-based GSI ndas
#  06/25/2006  HUI-YA CHUANG, modified to run 32 km ETA MOS
