07/06/2021· Atmospheric carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked for 2021 in May at a monthly average of 419 parts per million (ppm), the highest level since accurate measurements began 63 years ago, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.
07/02/2021· "By the time continuous observations began at Mauna Loa Volcanic Observatory in 1958, global atmospheric carbon dioxide was already 315 ppm," the NOAA states on its website. "On May 9, 2013, the ...
The Mauna Loa CO2 data are being obtained at an altitude of 3400m in the northern subtropics and represent the longest existing continuous record of CO2 since methodical measurements began in 1958 during the International Geophysical Year (IGY).

Scripps’ scientist Charles …
The first 12 years (1974–1985) of continuous atmospheric CO 2 measurements from the NOAA GMCC program at the Mauna Loa Observatory in Hawaii are analyzed. Hourly and daily variations in the concentration of CO 2 due to local sources and sinks are described, with subsequent selection of data representing background concentrations.
04/06/2020· Atmospheric carbon dioxide measured at Mauna Loa Observatory reached a monthly peak exceeding 417 parts per million (ppm) in May 2020, the highest monthly total ever recorded, scientists from Scripps Institution of Oceanography at the University of California San Diego and NOAA announced today. This year’s peak value recorded by Scripps was parts per million (ppm) higher …
25/06/2020· Fifth, year-over-year comparisons of Mauna Loa CO2 gives people a signal of planetary significance. It's true that Mauna Loa is just a spot on the map. But the year-over-year trend in the Mauna Loa CO2 is essentially the same as the trends at other observing stations. “CO 2 is rising everywhere, and at about the same rate” (Volk, 2008, pp ...
The first 12 years (1974-1985) of continuous atmospheric CO 2 measurements from the NOAA GMCC program at the Mauna Loa Observatory in Hawaii are analyzed. Hourly and daily variations in the concentration of CO 2 due to local sources and sinks are described, with subsequent selection of data representing background concentrations. A digital filtering technique using the fast Fourier transform …
25/06/2020· The purpose is to spur conversations and innovations for stabilizing GHGs in the atmosphere and ending the global climate crisis. CO2 measurements are made by two independent CO2 monitoring programs (NOAA and Scripps) at the Mauna Loa Observatory in Hawaii, about 3400 metres above sea level.
We forecast the annual average CO 2 concentration at Mauna Loa to be ± parts per million (ppm) higher in 2021 than in 2020. As a result, we forecast the 2021 annual average CO 2 concentration at Mauna Loa to be ± ppm (Figure 1). Figure 1. Forecast CO 2 concentrations at the Mauna Loa observatory, showing monthly (red curve ...
The Mauna Loa CO 2 data are being obtained at an altitude of 3400m in the northern subtropics and represent the longest existing continuous record of CO 2 since methodical measurements began in 1958 during the International Geophysical Year (IGY).
In 1958, Charles David Keeling began measuring atmospheric carbon dioxide at the Mauna Loa Observatory on the big island of Hawaii. This figure is a graph of the observatory’s measurements over time, which is now called the Keeling Curve. The “Educator Materials” document includes a captioned figure, background information, graph interpretation, and discussion questions. The “Student Handout” …
06/07/2021· The carbon dioxide data on Mauna Loa constitute the longest record of direct measurements of CO 2 in the atmosphere. They were started by C. David Keeling of the Scripps Institution of Oceanography in March of 1958 at a facility of the National Oceanic and Atmospheric Administration [Keeling, 1976].

The longest continuous record of atmospheric carbon dioxide levels (1958-present) comes from Mauna Loa Observatory in Hawaii. In many ways the mountain is the ideal location for studying the atmosphere. Isolated in the Pacific, it is far from major sources of pollution. Its high-altitude, lava-coated flanks are free of plants and trees, whose cycles of photosynthesis and respiration affect carbon …
