Commemorating the 69th anniversary of the continuous operations of the Mauna Loa Observatory.

This is a House Resolution (H. Res. 637) commemorating the 69th anniversary of the continuous operations of the Mauna Loa Observatory (MLO). The resolution recognizes MLO as a premier long-term atmospheric monitoring facility operated by the Global Monitoring Laboratory within NOAA’s Earth System Research Laboratories (ESRL). It emphasizes the ESRL’s mission to measure atmospheric constituents that influence Earth's climate and ozone layer, and notes MLO’s long-running role in tracking rising carbon dioxide and other key atmospheric parameters from its high-altitude location on Mauna Loa. The resolution also highlights MLO’s partnerships with national and international researchers, its four sites on Hawaii Island, and its cultural significance to the Native Hawaiian community. Importantly, the bill is ceremonial in nature and does not authorize new funding or impose new requirements; it signals congressional support for ongoing operations and public recognition of MLO’s contributions.
