METplus Practical Session Guide (Version 5.0) | Basic Verification Statistics Review


This session is meant as a brief introduction (or review) of basic statistical verification methods applied for various classifications of meteorological variables, and to guide new users toward their usage within the METplus system. It is by no means a comprehensive review of all of the available statistical verification methods available in the atmospheric sciences, nor every single verification method available within the METplus system. More complete details on many of the techniques discussed here can be found in Wilks’ “Statistical Methods In The Atmospheric Sciences” (2021), Jolliffe and Stephenson’s “Forecast Verification; A Practitioner's Guide in Atmospheric Science” (2012) and the forecast verification web page hosted by Australia’s Bureau of Meteorology.  Upon completion of this session you will have a better understanding of four of the common classification categories for meteorological verification, deterministic and probabilistic examples of those categories, and, depending on the gridded or point format of the data, what MET tool(s) to use for verification.
