Start of experimental exchange Data will be made available in BUFR (CREX), but not operationally. Start of operational exchange Data will be made available in BUFR (CREX) whereby some (but not all) Members rely on them operationally. Still the current alphanumeric codes will be distributed (parallel distribution). Migration complete At this date the BUFR (CREX) exchange becomes the standard WMO practice. Parallel distribution of TAC and TDCF may continue and will be discontinued step by step whenever possible with respective advance notification. TAC stopped (parallel distribution of TAC and BUFR stopped ) At this date parallel TAC and BUFR distribution is terminated. For archiving purposes and at places where BUFR (CREX) exchange still causes problems the alphanumeric codes may be used only for the exchange of data between two NMHSs.
