The GRIB edition 1 (GRIB1) was introduced in the Manual on Codes (WMO-No. 306) on 1 November 1987 (Rec.8 (CBS-Ext.(85))/Res.4(EC-XXXVIII)).
When the GRIB edition 2 (GRIB2) was adopted (Rec.5 (CBS-XII)/Res.4 (EC-LIII)), the Commission for Basic Systems (CBS) noted "GRIB edition 1 was still a valid code and would remain in use, for example, for aviation purposes" (general summary 6.2.103, abridged final report of CBS-XII). The GRIB2 became operational on 7 November 2001.
In 2006, the CBS-Ext.(06) "agreed to the request of ICAO to extend the use of GRIB 1 for the user of aviation products up to November 2010, because necessary equipment and software for GRIB2 will not be available in all countries by November 2008" (general summary 6.2.64, abridged final report of CBS-Ext.(06)).
The meeting agreed that GRIB edition 1 was to be separated from the Manual on Codes in consideration of no aviation requirements, which was confirmed by the ICAO representative, recognizing that the separation meant no allowance of GRIB1 for reporting only.
The agreement by the meeting will be forwarded to the next CBS session in 2016. If the separation is agreed by the CBS session, the edition 1 will be made available from the WMO Web site along with the previous editions of FM 94 BUFR and FM 95 CREX.
