Appendix A describes statistical concepts for validating and verifying deterministic forecasts.  A Cost/Benefit approach is explained to derive the most for customer forecasts from deterministic data.

Appendix B describes statistical concepts for validating and verifying probabilistic forecasts and for making the best use of NWP information. A Cost/Loss approach is explained to derive the most for customer forecasts from probabilistic data.

Appendix C gives a list of acronyms used in this guide and elsewhere.

Appendix D gives the current structure of IFS.

Appendix E gives useful references.

Appendix F gives historical techniques used in previous IFS cycles.

Appendix G gives ongoing issues with model products.
