About HMT

HMT insignia

The NOAA Hydrometeoroogy Testbed (HMT) is a joint OAR—NWS testbed motivated to make " Communities that are more resilient to the impacts of extreme precipitation on lives, property, water supply and ecosystems.” HMT is co-managed by the OAR Physical Sciences Division, and the NWS Weather Prediction Center in partnership with the National Water Center.

The mission of the testbed is "Improving forecasts of extreme precipitation and forcings for hydrologic prediction." HMT supports both OAR and NWS strategic objectives. For OAR, these include:

  • How can we improve forecasts, warnings, and decision support for high-impact weather events? (OAR overarching science question)
  • Identify new sources of predictive skill and improve predictions of weather, water, and climate through observations, understanding, and modeling of physical processes and phenomena of the coupled Earth system. (PSD overarching science goal)

HMT also supports five of the goals in the NWS Weather Ready Nation strategic plan:

  • Improve weather decision services for events that threaten lives and livelihoods
  • Deliver a broad suite of improved water forecasting services to support management of the Nation’s water supply
  • Improve sector-relevant information in support of economic productivity
  • Enable integrated environmental forecast services supporting healthy communities and ecosystems
Communities that are more resilient to the impacts of precipitation extremes on lives, property, water supply and ecosystems.
Motivating Question
Can forecasts of precipitation extremes be improved through an increased predictive understanding of underlying physical processes derived from enhanced regional observations and models?
To accelerate the development, prototyping, and use of advanced hydrometeorological observations and models to improve our physical understanding and representation of precipitation and surface processes, leading to improved monitoring and prediction of extreme events
To foster infusion of these advances into NOAA services, and to provide customized information for local and regional decision making
To support the broader needs for 21st Century precipitation information for flood and water resources management and improved ecosystem services
