Model Evaluation Tools (MET) verification statistics visualization
METViewer ingests MET output into a standard SQL database, which facilitates searching and sorting of the verification statistics. Using a user-supplied plot XML specification as input, METViewer gathers and aggregates statistics from the database and generates one or more plots. The three primary types of statistics handled are continuous, categorical and object based. Additional calculations, such as confidence intervals, bootstrap resampling and observation frequencies, are performed during the aggregation and plotting process. The primary focus, to date, has been to produce monthly and seasonal aggregations of statistics plotted over lead time, valid date and precipitation threshold, along with vertical profile plots, for a number of atmospheric variables, including: temperature, moisture and winds. The presentation will describe the tool and provide examples from recent projects.
