Description:
National Water Model (NWM) services continue to evolve with new and updated services and visualizations. This training provides a series of six short training videos about NWM services and how they are used in decision support in the National Weather Service.
Objectives:
- Recognize and describe the services from the National Water Model as of early 2020.
- Describe lead time periods available for each service.
- Recognize situations for which a service may be very useful.
- Explain important processes being represented.
- Define high water as it is used in the National Water Model
- Explain what Annual Exceedance Probability (AEP) is, which service is presented in units of AEP, and AEP’s relationship with Average Return Interval (ARI).
- Describe current limitations of each service.
