Introduction

This program reads selected GRIB2 fields from a file, adds a TOC Flag Field separator block and WMO Header in front of each GRIB2 field, and writes them out to a new file. The output file is in the format required for TOC's FTP Input Service, which can be used to disseminate the GRIB2 bulletins. This service is described at http://weather.gov/tg/ftpingest.html.

The "EXTRACT" variable in the namelist allows users to choose whether they want the entire GRIB2 message containing the requested field (extract=.false.), OR a GRIB2 message containing only the requested field (extract=.true.). Both options return the same message if the requested field is the only field in the GRIB2 message.
