Mountain Terrain Atmospheric Modeling and Observations (MATERHORN)
To address science needs and help improve the prediction of mountain weather, the U.S. Department of Defense has funded a research effort—Mountain Terrain Atmospheric Modeling and Observations (MATERHORN) Program—that draws on the expertise of a multidisciplinary, multi-institutional, and multinational group of researchers. The principal participants are the University of Notre Dame (lead); University of California, Berkeley; Naval Postgraduate School; University of Utah; and University of Virginia.
The ultimate goal of MATERHORN is to identify and study the limitations of current state-of-the-science mesoscale models for mountain terrain weather prediction and develop scientific tools to help realize leaps in predictability. The program consists of four components working symbiotically:
- The modeling component (MATERHORN-M) investigates predictability at the mesoscale.
- The experimental component (MATERHORN-X) mainly conducts field measurements at unprecedented spatiotemporal detail by deploying arrays of routine, high-end, and newly developed instrumentation.
- The technology development component (MATERHORN-T) enables currently untenable meteorological observations. The developments include an instrumented UAV, sensors for moisture and fog measurements, and a combined hot-film/sonic anemometer system for probing turbulence down to Kolmogorov scales.
- The parameterization component (MATERHORN-P) develops high-fidelity physics-based fundamental (quantitative) relationships for complex-terrain processes, which are implemented in mesoscale models followed by model evaluations.
This special collection includes a review article on the overall program and other research papers as they are published. Read More…
