Summary

The Mountain Terrain Atmospheric Modeling and Observations (MATERHORN) Program, funded by the Office of Naval Research (ONR), was designed to investigate complex-terrain meteorology over a wide range of scales, topographic features, and driving mechanisms by drawing expertise from multiple disciplines and by employing complementary research methodologies.

Two major field experiments or campaigns, denoted MATERHORN-X (Fall/Autumn 2012 and Spring 2013), were conducted at the Granite Mountain Atmospheric Sciences Testbed (GMAST) of the U.S. Army Dugway Proving Ground (DPG) in Utah, collecting high-resolution measurements focusing on conditions dominated by thermal circulations and strong synoptic forcing. Another smaller MATERHORN-X study focused on Fog formation was conducted in January 2015. Originally, all data collected was archived and distributed to the MATERHORN Community by the University of Notre Dame (UND) following each field campaign. As of late 2016, NCAR/EOL will provide access to the MATERHORN-X Final Data Archive.
