Published by DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2014-08-05T00:00:00.000+00:00
This data set contains continuous measurements of atmospheric carbon dioxide mole fractions from the NOAA/ESRL observatory at Mauna Loa, Hawaii. Data are expressed in hourly, daily and monthly averages in units of micromole/mole for the time period of 1974-2013. Data are archived at the NOAA National Climatic Data Center (NCDC), but are produced and available from NOAA Earth System Research Laboratory (ESRL).
