Forecast Verification Research

Mission of the Joint WWRP/WGNE Working Group on Forecast Verification Research

To plan and implement the verification component of WWRP;

To serve as a focal point for the development and dissemination of new verification methods for WWRP and EPAC, as required;

To facilitate and encourage training and dissemination of information on verification methodologies;

To take into account the needs of users so as to ensure the relevance of the practice of forecast verification;

To facilitate the development and application of improved diagnostic verification methods to assess and enable improvement of the quality of weather forecasts, including forecasts from numerical weather and climate models;

To encourage the sharing of observational data for verification purposes;

To encourage greater awareness in the research communitiy of the importance of verification as a vital part of numerical and field experiments rather than an "afterthought";

To promote collaboration among scientists conducting research on various aspects of forecast verification as well as with model developers and forecast providers; and

To collaborate on forecast verification with the Working Group on Numerical Experimentation (WGNE) and WCRP and in coordination with CBS.
