C PROGRAM HISTORY LOG:
C    2000-03   P. SHAFRAN original program
C    2001-03   P. SHAFRAN added Pentad data
C    2001-03   P. SHAFRAN added Mexico data
C    2001-11   P. SHAFRAN 32-km version
C    2001-12   P. SHAFRAN 32-km version
C                               - 32-km version:
C                               - CONUS data now in GRIB
C                               - blending of US and Canada using new LDAS mask
C                               - blending of US and Mexico using new LDAS mask
C                               - blending of Mexico and CMAP using 50/50 mask
C                               - No CMAP north of 50 degrees north
C    2004-03   P. SHAFRAN New version for 2003 and real-time R-CDAS:
C                         Uses CMORPH for oceans, NLDAS for Conus
C                         and US/Mexico for Mexico
C    2012-01   W. EBISUZAKI allow missing cmorph and us-mex data
C                          quick cleanup, minor bug fix,
C                          increase size of KPDS, KGDS
C                          enable reading us-mex precip
C                           typo incroduced with new us-mex dataset?
C    2013-01   W. EBISUZAKI fixed call to getgb
