Monthly time series of atmospheric carbon dioxide (CO2),
the relative amount of carbon-13 in CO2 (13C), hydrogen
(H2) carbon monoxide (CO), and methane (CH4) are examined
and related to each other and to an index of the status of ENSO. Making use of simple 12-month running mean
and difference filters isolates the year-to-year variability in the concentrations
and apparent sources of these constituents.
