User’s Guide¶
Foreword: A note to METplus Wrappers users
This User’s Guide is provided as an aid to users of the Model Evaluation Tools (MET) and it’s companion package METplus Wrappers. MET is a suite of verification tools developed and supported to community via the Developmental Testbed Center (DTC) for use by the numerical weather prediction community. METplus Wrappers are intended to be a suite of Python wrappers and ancillary scripts to enhance the user’s ability to quickly set-up and run MET. Over the next year, METplus Wrappers will become the authoritative repository for verification of the Unified Forecast System.
It is important to note here that METplus Wrappers is an evolving software package. The first release of METplus Wrappers have occurred in 2017. This documentation describes the 3.1.1 release in December 2020. Intermediate releases may include bug fixes. METplus Wrappers is also be able to accept new modules contributed by the community. While we are setting up our community contribution protocol, please send email to: met_help@ucar.edu and inform us of your desired contribution. We will then determine the maturity of any new verification method and coordinate the inclusion of the new module in a future version.
This User’s Guide was prepared by the developers of the METplus Wrappers, including Dan Adriaansen, Minna Win-Gildenmeister, George McCabe, Julie Prestopnik, Jim Frimel, John Opatz, John Halley Gotway, Tara Jensen, Jonathan Vigh, Mallory Row, Christana Kalb, Hank Fisher, Lisa Goodrich, Lindsay Blank, and Todd Arbetter.

Acknowledgments
We thank all the METplus sponsors including: DTC partners (NOAA, NCAR, USAF, and NSF), along with NOAA/Office of Atmospheric Research (OAR), NOAA/Office of Science and Technology Integration, NOAA/Weather Program Office (WPO, formerly Office of Weather and Air Quality), and the Naval Research Laboratory (NRL). Thanks also go to the staff at the Developmental Testbed Center for their help, advice,and many types of support. We released METplus Alpha in February 2017 and would not have made a decade of cutting-edge verification support without those who participated in DTC planning workshops and the NGGPS United Forecast System Strategic Implementation Plan Working Groups (UFS SIP WGs).
