Blue Hill Observatory & Science Center

Blue Hill Meteorological Observatory was founded in 1885 by Abbott Lawrence Rotch as a private scientific center for the study and measurement of the atmosphere., It maintains one of the longest continuous climate records in the nation, and 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 Observatory has also been recognized by the World Meteorological Organization as a Centennial Observing Station, one of only seven such sites in the United States. The Science Center, established in 1999, expands this mission by enhancing public understanding of atmospheric science.
