![]() In the last decade, this has occurred on about 15% of nights between midnight and 6 a.m. When the volcanic emissions arrive at the observatory, the CO 2 analyzer readings increase by several parts per million, and the measured amounts become highly variable for periods of several minutes to a few hours. MLO offers a unique testing environment for the Mini-LHR, as the altitude helps ensure the atmosphere sampled represents the background signal of the atmosphere. Under these conditions, a temperature inversion forms above the ground, and the volcanic emissions are trapped near the surface and travel down our side of the mountain slope. MLO is the site of the longest running measurements of atmospheric CO 2, begun in the late 1950s by Charles Keeling. We only detect volcanic CO 2 from the Mauna Loa summit late at night at times when the regional winds are light and southerly. ![]() These are the conditions we use to calculate the monthly averages that go into the famous 50-year graph of atmospheric CO 2 concentration. We know this because the CO 2 analyzer usually gives a very steady reading which varies by less than 3/10 of a part per million (ppm) from hour to hour. Since 1958, initially under the direction of Charles Keeling, followed by his son Ralph and later Elmer Robinson, Mauna Loa Observatory (MLO) has been monitoring and collecting data relating to atmospheric change, and is known especially for the continuous monitoring of atmospheric carbon dioxide (CO 2 ), which is sometimes referred to as the Keeling Curve. The information gathered there helps scientists protect habitats and settlements on Earth.Most of the time, the observatory experiences “baseline” conditions and measures clean air which has been over the Pacific Ocean for days or weeks. The Keeling Curve: Atmospheric CO 2 concentrations as measured at Mauna Loa Observatory. Mauna Loa Observatory performs important work tracking Earth’s changing climate. The curve describes the longest continuous record of CO2 in Earth’s atmosphere. He was the first researcher to report that the levels of CO2 in the atmosphere were consistently rising on Earth. The weather measurements made here are so sensitive that when the observatory was built in 1956 scientists asked the national park to. The observatory is a premier atmospheric research facility that has been continuously. He was a professor at Scripps Institution of Oceanography. Rainbow over NOAAs Mauna Loa Observatory on the Big Island of Hawaii. The measurements are displayed in a graph known as the “ Keeling Curve,” named after the late Dr. Perhaps the most notable, though, is the observatory’s measurements of carbon dioxide (CO2). Some of the gases they measure include carbon monoxide, methane, nitrous oxide, and sulfur dioxide. To detect any change in Earth’s climate, Mauna Loa measures different gases in the air. Scientists began studying the atmosphere at Mauna Loa in the 1950s. ![]() This means the air is relatively clean, which makes it easier for scientists to study. The observatory is approximately 3,400 meters (11,141 feet) above sea level and remains a long distance away from significant pollution sources. It is located in Hawaii on the side of Mauna Loa, the world’s largest active volcano. ![]() Mauna Loa Observatory’s location marks an ideal spot for sampling Earth’s air. This data is critical because the ozone layer protects us from harmful radiation produced by the sun’s ultraviolet rays. They also measure elements that may deplete the ozone layer. Mauna Loa Observatory is a station that measures elements in the atmosphere that contribute to climate change on Earth. ![]()
