From Glossary of Meteorology


  1. In expert systems, the determination of how well the task is performed.

    For weather forecast expert systems, it corresponds to forecast verification. Consequently, there is often confusion among meteorologists between validation and verification as used in artificial intelligence.

  2. Comparison of a measurement from a new instrument or technique with older, established measurements of the same property or parameter.
