MET Online Tutorial for METv8.0 | MODE-Time-Domain

MODE-Time-Domain Functionality

The MODE-Time-Domain (MTD) tool is available from MET version 6.0. It applies an object-based verification technique in comparing a gridded forecast to a gridded analysis. It defines 3-dimensional space/time objects, tracking 2-dimensional objects through time. It writes summary object information to ASCII statistics files and writes object fields to NetCDF format. The MTD tool can be used to quantify the duration of events and timinig errors.

MODE-Time-Domain Usage

View the usage statement for MODE-Time-Domain by simply typing the following:


At a minimum, the -fcst and -obs options must be used to specify the data to be processed. Alternatively, the -single option specifies that MTD should be run on a single dataset. The -config option specifies the name of the configuration file.

As with the other MET statisics tools, all gridded forecast and observation data must be interpolated to a common grid prior to processing. This may be done using the automated regrid feature in the MTD configuration file or by running copygb and/or wgrib2 first.
