Tribute Gifts

Make a donation in honor or memory of someone special to you. We can take care of acknowledging your gift as you would like.

By making a gift to Mount Washington Observatory, you sustain one of the longest continuous weather records in North America, year-round forecasts in the White Mountains that keep people safe, and educational programs that inspire the next generation of scientists.

A few highlights demonstrate the recent impact of your support:

Scientific Research and Technology: New funding will modernize the Mount Washington Regional Mesonet, upgrade its capabilities, and double its size during the next three years to advance our extreme weather forecasting and cutting-edge research. We’ll also join a network of organizations in the Northeast dedicated to improving access to real-time weather data to aid planning by businesses and communities throughout our region.

“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

Education and Outreach: New field trips brought more than 350 middle school students to the summit for unforgettable adventures in science, technology, engineering, and math (STEM), increasing access to Mount Washington. New school-day, after-school, and virtual programs were launched this fall with more than 800 backpacks containing weather stations and other goodies given to young students.

“My seventh 7th graders became very interested in weather after receiving the backpacks with the weather stations from the Observatory. We’ve done weather observations before, but students didn’t have great follow-through. They loved being able to use their weather stations and collect info at home. They also have become very interested in following the weather at the summit.”
-Patti Dugan-Henricksen, Groveton Middle School teacher

Recreation and Safety: We reported 8,760 hourly observations and published 1,460 specialized forecasts in the past year. During the extreme cold in February, our dedicated weather observers measured a -47 °F air temperature, matching the Observatory’s all-time record low previously set on Jan. 28, 1934.

“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) Partnership and Volunteer Coordinator

Please consider supporting us this holiday season, a time when your gift can make a real impact. Your support solves a critical challenge, ensuring we can continue our work tracking key indicators of how seasons are changing in alpine environments. Our 90-year climate record provides vital and verifiable data for researches, meteorologists, and students studying Earth’s weather and climate.
