A resolution commemorating the 69th anniversary of the continuous operations of the Mauna Loa Observatory.

This is a nonbinding Senate resolution commemorating the 69th anniversary of the continuous operations of the Mauna Loa Observatory (MLO). It recognizes MLO as a premier long-term atmospheric monitoring facility that is part of NOAA's Global Monitoring Laboratory within the Earth System Research Laboratories and highlights its mission to measure atmospheric constituents that influence Earth's climate and ozone layer. The resolution notes MLO’s role in providing long-running records of tropospheric gases (such as carbon dioxide, methane, and other key pollutants) and its unique geographic location on Mauna Loa on Hawaii Island, which makes it especially valuable for sampling the troposphere above the marine inversion layer. It also acknowledges MLO’s four sites on Hawaii Island and the dedicated workforce there, emphasizes the research it has supported with national and international partners, and affirms the Senate’s continued support for MLO’s operations and its cultural significance to the Native Hawaiian community. As a resolution, it expresses the sense of the Senate rather than creating new policy, funding, or regulatory requirements.
