Blue Hill Meteorological Observatory, located at the top of a scenic mountain range south of Boston, is a unique American institution. Founded in 1885 by Abbott Lawrence Rotch as a private scientific center for the study and measurement of the atmosphere, it was the site of many pioneering weather experiments and discoveries. The earliest kite soundings of the atmosphere in North America in the 1890s and the development of the radiosonde in the 1930s occurred at this historic site.
Today, the Observatory is a National Historic Landmark and remains committed to continuing its extensive, uninterrupted climate record with traditional methods and instruments. The recently established Science Center expands this mission by enhancing public understanding of atmospheric science.
