Stage II analyses were used as the verifying dataset for all of these plots.
- Note: There have been some outages in data. These stats were only
run if there was a subdomain selected and all forecast and Stage II data were present. Outages to date include:
- 5/3-5/5 (Stage II missing)
- 5/8-5/12 (missing EMC forecasts)
- 5/14-5/17 (missing all forecasts)
MET
MET is designed to be a highly-configurable, state-of-the-art suite of verification tools. It was developed using output from the Weather Research and Forecasting (WRF) modeling system but may be applied to the output of other modeling systems as well.
- MET provides a variety of verification techniques, including:
- Standard verification scores comparing gridded model data to point-based observations
- Standard verification scores comparing gridded model data to gridded observations
- Object-based verification method comparing gridded model data to gridded observations
The version of MET used for this project is Version 1.0.
More information about MET, including release dates, is available at the official MET website at the Developmental Testbed Center.
This site is for demonstration purposes. Although we aim to provide real-time evaluation of HWT Spring Program fore
casts, it should not be considered a formally operational site.
MET is a suite of forecast evaluation tools. This site demonstrates two of those tools, MODE and Grid_stat.
MODE
MODE (Method for Object-based Diagnostic Evaluation) is forecast evaluation method developed at the National Center for Atm ospheric Research. Unlike traditional verification approaches, MODE uses a fuzzy engine to identify "objects" (i.e. areas of interest), then compare the attributes of the identified objects (and forecast/observation object pairs).For more about MODE, see:

Grid_stat
Grid_stat is a component of MET that primarily implements traditional evaluation methods for gridded datasets. This includes traditional verification metrics such as the Equitable Threat Score (ETS), Bias, and a host of other statisti cs.News
Version 1.0 of MET is currently available. The next release of MET, Version 1.1, is planned for Spring 2008.
