  2. DCP Migration from TAC to TDCF • Traditional Alphanumeric Code (TAC) : SYNOP • Table Driven Code Forms (TDCF): CREX, BUFR • On-going migration from TAC to TDCF according to agreed planhttp://www.wmo.int/pages/prog/www/WMOCodes/MigrationInfoDocum.html#Information • In the case of DCPs in remote areas (e.g. buoys)upgrading the DCP for TDCF can be unpractical (very expensive or unfeasible) • An alternative is to perform TAC-TDCF conversionof DCP messages before their injection into GTS • Question: where, by whom should this be done ?

  3. What is the DCP retransmission circuit ? Satellite (DCS) operator- EUMETSAT- NESDIS- JMA/MSC QualityControl GTS TDCF Conversion NMHS owning the DCP

  4. What is the DCP retransmission circuit ? Injection into the GTS by the nearest entry :- DWD/Offenbach- NWS/Washington- JMA HQ/Tokyo- .. Satellite (DCS) operator- EUMETSAT- NESDIS- JMA/MSC ? ? GTS TDCF Conversion TDCF Conversion QualityControl GTS TDCF Conversion NMHS owning the DCP

  5. Issue to be looked at by the IPET-DRC
