Scripps CO2 Program Data

About this Collection
The Scripps CO2 program was initiated in 1956 by Charles David Keeling and operated under his direction until his passing in 2005. It is currently being continued by Ralph F. Keeling, who also runs a parallel program at SIO to measure changes in atmospheric O2 and Ar abundances (Scripps O2 Program).The Scripps CO2 program has made measurements of atmospheric CO2 concentration and the isotopic abundances 13C/12C, 14C/C, and 18O/16O ratios of CO2 from a network of stations from nearly Pole to Pole, along a Pacific transect. The primary (in situ) record from Mauna Loa Observatory, Hawaii is based on measurements made with an analyzer at the site. In situ records are also available from La Jolla. At all other sampling stations, the records are based on flask samples returned to the laboratory at the Scripps Institution of Oceanography for analysis. Flasks have also been redundantly collected at Mauna Loa and La Jolla.
Current results, including data sets and graphics, are available at http://scrippsco2.ucsd.edu from the ongoing program to measure CO2 and chemical species.

Measurements of atmospheric CO2 concentration in our program began in 1957 at La Jolla, California and at the South Pole, and in 1958 at Mauna Loa Observatory. These measurements were gradually extended during the 1960's and 1970's to comprise sampling at an array of stations from the Arctic to Antarctica. Isotopic measurements began in 1978 at selected stations, expanding over time to include additional stations. View this collection on the contributor's website.
