    • NOAA Atmospheric Carbon Dioxide Mole Fractions from Mauna Loa Observatory, Hawaii, United States

    Metadata Updated: September 19, 2023

    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).

    Lineage CO2 mixing ratios reported in these files were measured by a nondispersive infrared absorption technique. Descriptions of the sampling, measurement, and calibration procedures are given in Komhyr et al., 1989; Thoning et al., 1989, and Zhao and Tans, 2006.
