![]() Scientific instruments at the facility includes analyzers operated independently by Scripps and NOAA to continuously measure concentrations of carbon dioxide (CO2) as they change in the atmosphere. This webpage presents a summary and many links to informaiton the 2022 volcanic eruption at Mauna Loa which interrupted the atmospheric CO2 record which serves as the leading signal of coming changes in climates and environments worldwide, and which, we hope, will soon straighten and bend down to become a signal that shows past and coming progess to resolve the current crisis. This is the remote, premiere atmospheric monitoring observatory which scientists have been using to monitor and collect data for understanding changes to the planet's atmosphere and climate since the 1950s. the next day, lava flows cut through powerlines on the Observatory Road access route which supplies electricity to the nearby Mauna Loa Observatory (MLO). Mauna Loa is also the world's erupted on Novemat 11:30 p.m. It resulted in discoveries that advanced human understanding of our impact on the atmosphere, climate and environment-and our capacity to address the impacts. This CO2 record generated the Keeling Curve which is now "an icon of modern climate science" ( ACS). Located 3,400 metres above sea level, this atmospheric research facility is home to the world's longest-running instrument record for CO2 measurements. Since March 1958, scientists have been using high-precision instruments to measure carbon dioxide (CO2) in the air at the remote Mauna Loa Observatory (MLO) in Hawaii. Then, links to external reports and coverage is listed in chronological order. As of April 24, 2023, it is not yet known when NOAA will resume its CO2 measurements at Mauna Loa.Ī more detailed account of events is next. On March 9, 2023, Scripps resumed its measurements of CO2 levels at the Mauna Loa Observatory. This will provide an overlap which will allow scientists to compare measurements at the two nearby locations. The two monitoring programs will continue the Maunakea measurements for about a year after measurements resume at the Mauna Loa facility. Scripps began its measurements at this temporary site on December 14, 2022. NOAA began its Maunakea measurements on December 8, 2022. To continue the Mauna Loa CO2 record, temporary measurement site was set up at the nearby summit of Maunakea. The USGS reported that lava flows travelled 12.1 miles and covered an area of 16.5 square miles. Volcanic activity began to settle down on December 9, 2022, and lava flows stopped expanding by December 13, 2022. This incident caused a pause in CO2 measurement programs at Mauna Loa: the NOAA CO2 monitoring program (NOAA GML), and the Scripps CO2 monitoring program (Scripps / UCSD). This global atmosphere monitoring facility is best known for producing the longest running record of high-precision measurements of CO2 levels in the Earth's atmosphere. About seven hours later, lava flows buried the access road and cut electrical powerlines to the remote, world-famous Mauna Loa Observatory. The Mauna Loa volcano erupted November 27, 2022. ![]()
