The CBS standardised procedures for verification of deterministic NWP products are defined in Manual on the Global Data-processing and Forecasting System: Annex IV to the WMO Technical Regulations (available from WMO library at https://library.wmo.int/index.php?lvl=notice_display&id=12793records/item/35703-manual-on-the-global-data-processing-and-forecasting-system), appendix 2.2.34.
The 16th WMO Congress (2011) approved a number of significant changes to these standard procedures, as recommended by CBS-Ext.(2010). LC-DNV will coordinate and facilitate the transition to the updated procedures. All GDPFS centres are encouraged to read the information and guidance provided and to implement these changes as soon as possible.
