The 16th WMO Congress (2011) approved a number of significant changes to the standard procedures for verification of deterministic NWP products, as recommended by CBS-Ext.(2010).
LC-DNV coordinates and facilitates the implementation of the standard procedures. All GDPFS centres are encouraged to read the information and guidance provided and to implement the guidelines in the generation of verification scores.
- Standard verification procedures:
- Manual on the Global Data-processing and Forecasting System: Annex IV to the WMO Technical Regulations (available from WMO library, currently at https://library.wmo.int/records/item/35703-manual-on-the-global-data-processing-and-forecasting-system or please use the Search on the WMO website), appendix 2.2.34.
- Implementation guidelines (the document in preparation).
- Lead Centre guidelines for data exchange:
- Auxiliary data: climatology fields and station lists
The status of implementation of standard procedures in participating centres is available in a table maintained by the LC-DNV.
