" Atmospheric CO2 record based on ice core data before 1959 and yearly averages "
" of direct observations from Mauna Loa and the South Pole after and "
" including 1959 (from Scripps CO2 Program). "
" "
" Ice core data from (Ethridge et. al., 1996; MacFarling Meure et al., 2006) and "
" yearly averages of direct observations from Mauna Loa and the South Pole after and "
" including 1959 (from Scripps CO2 Program). "
" "
" Annual mean CO2 concentration for Mauna Loa and South Pole starting in 1959. "
" These values are derived from seasonally detrended monthly mean values for each station "
" that have been filled with values from the spline fit when monthly averages are "
" not available. Average values are centered on 1-July of each year. "
" "
" Mauna Loa and South Pole CO2 concentrations are measured on the '12' calibration scale "
" "
" For Mauna Loa Observatory, Hawaii: Latitude 19.5ÿN Longitude 155.6ÿW Elevation 3397m "
" For South Pole: Latitude 90.0ÿS Elevation 2810m "

" Status of Scripps CO2 data and correspondence: "
" "
" These data are subject to revision based on recalibration of standard gases. Questions "
" about the data should be directed to Dr. Ralph Keeling (rkeeling@ucsd.edu) and "
" and Dr. Stephen Piper (scpiper@popmail.ucsd.edu), Scripps CO2 Program. "
