These Multi-Variate MODE ------------------ -Traditionally, MODE defines objects by smoothing and thresholding data from a single input field. MET version 10.1.0 extends MODE by adding the option to define objects using multiple input fields. As described in :numref:`MODE-configuration-file`, the **field** entry in the forecast and observation dictionaries define the input data to be processed. If **field** is defined as a dictionary, the tradition method for running MODE is invokes, where objects are defined using a single input field. If **field** is defined as an array of dictionaries, each specifying a different input field, then the multi-variate MODE logic is invoked. The object definition criteria can be specified separately within in field array entry to define objects for that field. The **multivar_logic** string defines the boolean logic for combining objects together from each of the inputs. The boolean logic uses integers from 1 to N, the number of input fields, to refer to the N-th field. Note that the multi-variate MODE forecast and observation object definition logic does not need to match. The result of the boolean logic is the creation of forecast and observation *super* objects, which are written to NetCDF output files. Users can then configure and run traditional MODE to compare the forecast super object to the observed super object. +Traditionally, MODE defines objects by smoothing and thresholding data from a single input field.
