MLO

MLO is located on the north flank of Mauna Loa Volcano, on the Big Island of Hawaii. Due to its remote location in the Pacific Ocean, high altitude (3397 meters, or 11,135 feet above sea level), and great distance from major pollution sources, MLO is a prime spot for sampling the Earth's background air in the well mixed free troposphere. The observatory protrudes through the strong marine temperature inversion layer present in the region, which separates the more polluted lower portions of the atmosphere from the much cleaner free troposphere. More on MLO Site Location..... MLO began continuously monitoring and collecting data related to climate change, atmospheric composition, and air quality in the 1950's. Today, the observatory is best known for its measurements of rising anthropogenic carbon dioxide (CO 2) concentrations in the atmosphere. This trend is sometimes referred to as the "Keeling Curve". MLO is also known for its measurements of ozone, chemicals that destroy ozone (such..
