Station near Barrow, Alaska. August 1965.
ABSTRACT
The results of the measurements of carbon dioxide in
air at Barrow, Alaska, are presented. Reference gas com-
parison data are tabulated, and methods of calculations
are discussed. The average daily concentrations of
atmospheric carbon dioxide are tabulated for the period
10 July 1961 to 15 September 1967. The diurnal variations
of carbon dioxide during this period are also presented.
