Blue Hill Observatory Designated as a "Centennial Observing Station"  

bho historical photo In recognition of its long-term and high quality climate record, the Blue Hill Observatory has been selected by the World Meteorological Organization (WMO) to receive its new designation as a "Centennial Observing Station". Recognizing the need to preserve and to maintain long-term surface observing stations for their important role in the continuing study of climate, the WMO has identified sixty sites around the world that satisfy their specific criteria for receiving this designation, including having been founded at least 100 years ago. Among this inaugural selection, the Observatory is one of only three sites in the United States to receive this recognition. Blue Hill continues to maintain an un-interrupted and extensive climate record that was founded by Abbott Lawrence Rotch more than 132 years ago.
In the words of the WMO, "Long-term meteorological observations are part of the irreplaceable cultural and scientific heritage of mankind that serve the needs of current and future generations for long-term high quality climate records."

We gratefully acknowledge Dr. Jay Lawrimore and our colleagues at the NOAA National Centers for Environmental Information for nominating the Blue Hill Observatory for this recognition.
