Station plots of daily averages of CO2 and O2/N2

The upper panel shows O2 concentrations, reported as relative changes in O2/N2 ratio in per meg units; the lower panel shows CO2 concentrations in ppm units (i.e. ╬╝mol of CO2 per mol of dry air). Points are daily average concentrations. Curves are fits to the data consisting of a spline with a controlled stiffness and a 4-harmonic fit.
