The standard procedures for verification of surface variables are defined in the 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=12793), appendix 2.2.34.
ECMWF in the capacity of LC DNV collects and archive the scores. Data are
At the WMO Commission for Basic Systems (CBS) ET-OWFPS Meeting on 22-24 October 2014 in Geneva, a draft document on standardized surface verification of deterministic NWP products was agreed. The document specifies the content of the future exchange of surface scores between global centres and is available here: Standardized Surface Verification for Deterministic NWP.
ECMWF will be collecting and archiving the scores. Data will be exchanged in an ASCII-based format which is simple but flexible and is similar to the format used WMO exchange of domain-averaged upper-air scores.
