Thank You for your Support!

Thank you for your finacial commitment to research and education in support of the Mount Washington Observatory!
I know support is a choice and right now the need is great everywhere. Then why Mount Washington Observatory? Its about the impact! We are passionate about the weather and the environment we live in. We know that what happens on Mount Washington has an impact. It gives researchers and scientist a glimpse into our weather, atmosphere, environment and climate world-wide. The data that comes from our small section of the globe influences analytic models, testing scenarios, flight paths, and even your everyday decision on what to wear!
We need your support to stay at the top of the mountain in order to expand our 85 year data set used to inform science and education efforts as we continue our impact both daily and longterm. Its imperative this year that we double down on our effort to firmly sustain the Observatory by adding to our current operating capitol and build for the future. I'm not shy in telling you that it takes millions to operate and maintain this organization and we can't do it without you.

Your gift will have a direct and immediate impact. Mount Washington Observatory matters and your support matters to us. Please help us continue our long and storied history and to build a sustainable endowment by making a tax-deductible donation today.
