Mauna Loa Observatory (MLO) (http://www.mlo.noaa.gov/) is an atmospheric baseline station. Since the mid 1950's MLO has been continuously monitoring and collecting data relating to atmospheric change, and is known especially for their continous monitoring of atmospheric Carbon Dioxide (CO2) levels. The observatory is under the Climate Monitoring and Diagnostics Laboratory (CMDL) which is part of the National Oceanic and Atmospheric Administration (NOAA).
The latest observation of CO2 concentrations from MLO can be found at Climate Monitoring and Diagnostics Laboratory Data Center (http://www.cmdl.noaa.gov/ccgg/insitu.html). Note: There are a number of datasets provided on this page. The MLO CO2 data is depicted by the RED datapoints. CO2 levels are shown on the left side of the graph.
Mauna Loa Observatory (MLO) has activities at five sites. The primary observing site is located at the 11,000ft level on Mauna Loa north slope. The administration and data processing is done in the Hilo office. Kulani Mauka is a rain collection site. Cape Kumukahi is a flask sample site located on the eastern most point of Hawaii. The old Hilo airport is where weekly ozonesonde flights are prepared and launched.

MaunaLoa is an active volcano in the Hawaiian Islands which forms the core of the island of Hawaii.
The MaunaLoa Solar Observatory has long been prominent in observations of the Sun.
The most interesting are the volcanoes of Kamtschatka, in which there is an oft-renewed struggle between opposing forces--the snow and glaciers predominating for a while, to be in their turn overpowered by torrents of liquid fire.
