The service provides functions for visualizing data about the effectiveness of meteorological models to help evaluate their predictive success. A web-based tool plots measures of model accuracy using functions of the R statistical package. The web service generates XML serializations specifying each data plot, along with supporting resources to enable visual display.
API methods support listing of available meteorological databases, forecast variables they store, and values for those variables from a selected database. Methods allow iteration for a range of selected databases, variables, and data values to generate a specification for a data plot to be generated by the visualization service.
