The Mauna Loa station is the oldest in the world to measure carbon dioxide.
But those monitoring stations aren't seen as a world mark like the one at Mauna Loa, Hawaii.
The long-term measurements at Mauna Loa were started by a Scripps Institution of Oceanography scientist called Charles Keeling.
When we started monitoring it at Mauna Loa in 1957, CO2 was growing at about 0.75 ppm annually.
In 2012, monitoring stations in the Arctic measured 400 parts per million, but this is a new high at Mauna Loa.
Since scientists began measuring at Mauna Loa in 1958, the concentration of carbon dioxide has been increasing every year, NOAA said.
We met in 1985 and got married in 1988 at a Mitsubishi car preview in Hawaii at the Mauna Kea Westin Hotel.
The other, which is already working, occupies a perch on Mauna Kea.
With this approval, the BLNR has recognized TMT's goal of responsible development and environmental stewardship of Mauna Kea in close partnership with local interests.
ENGADGET: Hawaii clears land use for the Thirty Meter Telescope, construction to start in 2014
The Keck interferometer, now under construction at Mauna Kea on Hawaii, will combine four 1.8-metre telescopes to mimic a 100-metre telescope in just this way.
Spend a night or two in Hilo, taking time to day-hike on Mauna Kea or to drive partway up the mountain for stargazing after dark.
Located remotely from other sources of air pollution, Mauna Loa is commonly considered one of the most reliable places to measure concentrations of gases in the atmosphere.
PS1 is the experimental prototype for a larger telescope to be built called PS4, which will have four times the power of PS1 and is planned for Mauna Kea in Hawaii.

The biggest that have ever been built are those in the two ten-metre (394 inch) Keck telescopes on Mauna Kea, but each of those had to be assembled from 36 separate pieces.
The Mauna Loa monitoring station is operated by the U.S. National Oceanic and Atmospheric Administration (NOAA) and sits at an altitude of about 12, 000 ft in the middle of the Pacific.
The infra-red radiation emitted by the dust can also be used to measure the size of the ring directly, and this has been done using the Keck telescope on Mauna Kea, Hawaii.
For the first time, scientists measured an average concentration of atmospheric carbon dioxide of 400 parts per million in Mauna Loa, Hawaii, where the National Oceanic and Atmospheric Administration observatory is located, on Thursday.
The TMT Board expresses our strong commitment to respect the long history and cultural significance of Mauna Kea to the Hawaiian people, and has committed annual funding for local community benefits and education in Hawaii.
ENGADGET: Hawaii clears land use for the Thirty Meter Telescope, construction to start in 2014
The Hawaiian Board of Land and Natural Resources (BLNR) announced that it has granted a permit to the Thirty Meter Telescope (TMT) project to build and operate the next-generation observatory near the summit of Mauna Kea.

Carbon dioxide levels in the atmosphere are currently the highest on record, according to preliminary data from the Earth Systems Research Laboratory at Mauna Loa in Hawaii where measurements of CO2 have been recorded for nearly half a century.
