Between March 1977 and February 1982, 517 samples of air were collected in 51 glass flasks at four stations in the northern hemisphere near the Pacific ocean and at the South Pole. First, the CO2concentration of each sample was determined by nondispersive infrared gas analysis, and then the 13C/12C...
