Research & Product Testing

Mount Washington’s location at the convergence of three major storm tracks, combined with its elevation and unique topography, create extraordinary weather extremes unlike anywhere on Earth. It’s the ideal natural laboratory to learn about weather, climate, atmosphere and biosphere.

Mount Washington Observatory’s weather station, located at the 6,288-foot summit of Mount Washington, is one of only a handful of permanently-staffed mountaintop stations in the world, and the only one of its kind in the Western Hemisphere. The Observatory’s robust technological infrastructure, skilled staff scientists and full-service logistical support make it a truly remarkable research destination.

Striving to advance understanding of atmospheric and climatic processes and their impacts on Northeastern U.S. ecosystems, Mount Washington Observatory conducts collaborative research that encompasses multiple scientific disciplines. The Observatory also conducts testing for consumer and industrial products, and serves as an integral partner in the deployment, testing and monitoring of scientific equipment.

Weather and Climate
Mount Washington Observatory has a long, proven track record in climate research. We maintain one of North America’s longest continuous climate records, containing hourly observations dating back to the mid-1930s. We also operate a network of remote instrument stations throughout the Presidential Range. This unique data set and comprehensive array of surface data make Mount Washington Observatory ideally suited to host or collaborate on many kinds of climate research.

Air Quality
Mount Washington Observatory is located atop the tallest mountain in the northeastern United States, in free air, and far from urban centers. This remote, rural, high altitude site is well situated for the observation of mid-tropospheric chemistry, the study of regional air quality and long-range transport of aerosols. The Observatory has a history of participation in air quality research, such as being an air quality monitoring site in the University of New Hampshire's AIRMAP project for twelve years.

Instrument Siting and Product Testing
Mount Washington’s elevation and extraordinary conditions provide the ultimate challenge—if a product can handle Mount Washington, it can handle anything. Manufacturers of industrial products for aerospace, aviation, healthcare, military and scientific applications have chosen Mount Washington Observatory as a trusted partner in product testing. The Observatory has also tested consumer products ranging from windows and ice scrapers, to tents, outerwear and even skin cream.

Learn more about our robust siting and testing capabilities on our product testing page.
With our Mount Washington Regional Mesonet, we offer a diversity of testing sites alternative to Mount Washington for evaluating products at various altitudes, under an array of weather conditions.
