NOAA Atmospheric Carbon Dioxide Mole Fractions from American Samoa Observatory

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 | Catalog Last Checked: August 03, 2026 at 06:41 AM | Dataset Last Updated: August 05, 2014 at 12:00 AM
This data set contains continuous measurements of atmospheric carbon dioxide mole fractions from the NOAA/ESRL observatory at American Samoa. Data are expressed in hourly, daily and monthly averages in units of micromole/mole for the time period of 1976-2013. Data are archived at the NOAA National Climatic Data Center (NCDC), but are produced and available from NOAA Earth System Research Laboratory (ESRL).
