Summary
Abstract: This dataset consists of carbon dioxide (CO2) concentrations (ppmv) from the
Scripps Institution of Oceanography (SIO) air sampling network. The
network consists of five stations: Mauna Loa, Hawaii; Barrow, Alaska;
Cape Matatula, American Samoa; South Pole, Antarctica; and, Alert,
NWT, Canada. Data from the following previously unpublished sites were made
available in 2004: Christmas Island, Baring Head, Kermadec Island, and La
Jolla Pier.

Atmospheric concentrations of CO2 from Mauna Loa represent the longest
continuous record of atmospheric CO2 measurements.

Daily atmospheric CO2 concentrations from the Mauna Loa site are also
available as a CDIAC Numeric Data Package - NDP-001 which is available
on ftp in the directory:
"ftp://cdiac.esd.ornl.gov/pub/maunaloa-co2/"

Atmospheric CO2 concentrations were obtained at the following stations:

Mauna Loa, Hawaii (1958 - 2002)

All of the above data are tabulated as monthly averages of atmospheric
CO2 concentrations in parts per million by volume (ppmv). All of the
data are available online from CDIAC.
