Thank you for your commitment to our work. You make the difference in sustaining our efforts to inspire thousands of young students and adults with our educational programs, undertake groundbreaking research, and provide weather forecasts and data that fuel the national conversation.

The past year was an incredible turning point that broadened our impact on weather research and learning. Below are just a few recent examples of all that your support has enabled us to accomplish.

Education & Outreach



  • School memberships grew from seven to 22 member schools.

  • Field trip programs grew from 12 to 32 trips annually, including five winter trips. During the past year, we hosted 830 students on field trips to our summit weather station.

Research & Technology


  • An expedition team installed one of our custom wind sensors on Mount Aconcagua (22,769 ft) in Argentina, supporting high-altitude wind research and extending our observational reach into the Andes.

  • This summer, we’ll publish the first annual White Mountains Almanac that examines the climatology and biology of our region for visitors, educators, and researchers.

Forecasting & Recreational Safety


  • We started daily statewide forecasting for New Hampshire and Vermont, providing audio and text forecasts to New Hampshire Public Radio and Radio Vermont Group.

  • We began a multi-year project to modernize and expand our Mount Washington Regional Mesonet, our network of automated weather stations, to more than 50 locations with new capabilities including ground-based doppler LiDAR located at Bretton Woods Ski Area. This infrastructure represents the future of weather science.
