“Long-term and robust meteorological measurements in the Northeast mountains are sparse. Fortunately, the summit of Mount Washington has one of the longest (since 1932) high-quality montane data sets.”
Georgia Murray, Appalachian Mountain Club staff scientist

“The Observatory probably has more experience than anybody around the world at measuring the weather in an extreme location.”
Dr. Baker Perry, National Geographic Explorer

“I think this was probably the first time any of the students had thought about data science. They realized that graphs aren’t just a math class exercise but that they actually tell stories.”
Patti Dugan-Henricksen, Groveton Middle School teacher

“The Higher Summits Forecast is critical to hooking people in with data. The weather could make or break your trip and cause you to get into trouble.”
John Marunowski, White Mountain National Forest (WMNF)
