註釋A comprehensive technique for the objective analysis of scalar and of vector fields which has been developed is known as the Fields by Information Blending (FIB) technique. The FIB technique treats information as a metered commodity. It assembles all available information, which must include suitable weighting, and blends the information into resultant analyses and associated distributions of resultant resolution weight. In the FIB context, all information statements must include both parameter estimates and associated reliabilities. Any statement of information, whether observation or analysis value at a grid point, is incomplete without an associated reliability. For an independent piece of information the reliability, or report weight, is defined as the inverse of the error variance inherent in the observation and/or associated with the class of observation. For a statement of resolution the associated reliability, or resolution weight, is the inverse of the unresolved variance. The FIB technique is based entirely on rules for adding uncorrelated variance contributions and for adding independent information.
