Observatories
The location of Mauna Loa has made it an important location for atmospheric monitoring by the Global Atmosphere Watch and other scientific observations. The Mauna Loa Solar Observatory (MLSO), located at 11,155 feet (3,400 m) on the northern slope of the mountain, has long been prominent in observations of the Sun. The NOAA Mauna Loa Observatory (MLO) is located close by. From its location well above local human-generated influences, the MLO monitors the global atmosphere, including the greenhouse gas carbon dioxide. Measurements are adjusted to account for local outgassing of CO2 from the volcano.
Since October 2006, the Array for Microwave Background Anisotropy (AMIBA) has been exploring the origin of the universe.
The Hawaiian Volcano Observatory maintains seismic sensors and a web cam on Mokuʻāweoweo.
