This House Resolution commemorates the 69th anniversary of the continuous operations of the Mauna Loa Observatory (MLO) , a critical atmospheric baseline station within NOAA's Global Monitoring Laboratory. The MLO's mission is to measure atmospheric constituents, such as carbon dioxide and methane, that influence Earth's climate and ozone layer. Its unique location on Mauna Loa Volcano makes it a premier facility for long-term atmospheric monitoring, especially for sampling the troposphere. Since its establishment in 1956, the MLO has continuously observed increasing global atmospheric carbon dioxide concentrations and hosted numerous research programs. The House of Representatives recognizes the monumental contributions of the MLO's research and data to global leadership in atmospheric science. Furthermore, the resolution reaffirms strong support for the MLO's ongoing operations, including its four sites on Hawaii Island, and honors the cultural significance of Mauna Loa to the Native Hawaiian community.
