The HMT website will be unavailable for 24 hours starting Friday, March 6th at 5:00pm MT due to building maintenance.

HMT Overview

HMT insignia

The NOAA Hydrometerology Testbed (HMT) conducts research on high-impact regional precipitation, weather and land surface conditions. HMT fosters transition of scientific advances and new tools into forecasting operations to better balance water resource demands and flood mitigation strategies in a changing climate.

HMT addresses its goals through innovation, demonstration and infusion across key major activity areas. HMT's regional implementations started in California. Additional pilot projects have been initiated in the Pacific Northwest, Southeast and Rocky Mountain West.

HMT is managed by NOAA’s Physical Sciences Division (PSD) in the Earth System Research Laboratory, and is implemented at both PSD and NOAA's Weather Prediction Center.

HMT also collaborates with the National Weather Service at local and regional levels as well as other national, regional, and local agencies, and universities.

Guided both by NOAA service requirements, stakeholder needs, and emerging scientific questions and new technologies, HMT directly engages decision makers and scientists in research and development processes. New ideas, technologies and predictive models are developed, demonstrated, evaluated and refined through the testbed, and are transitioned to operations/applications.

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
