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.
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.
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.
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.
