Introduction

-fix_ncep is a "set" option that replaces certain NCEP-defined time ranges by the WMO equivalents. The current (7/2008) wgrib2 needs this option in order to correctly print out the time ranges for NCEP-defined time ranges.

The -fix_ncep option changes the memory image of the grib message. Therefore, if you want the NCEP time range, you must have the -grib or -grib_out option before the -fix_ncep option. Otherwise you will get the WMO time range.

Caution: expect this option to change as more NCEP time ranges are added

Usage

-fix_ncep

Example

wgrib2 -fix_ncep in_grib -grib out_grib
