A meteorological tower is provided in a flux site and a solar array is positioned on the tower to provide power. A laser on the tower receives power from the solar array and produces a laser beam. A multiplicity of individual laser absorption spectroscopy gas cells positioned on the meteorological tower collect samples of the atmosphere. An optical cable connects the laser to each of individual las cell and direct the laser beam into each cell. Each cell includes a multiplicity of mirrors positioned so that the laser beam makes a multiplicity of passes through the samples. An analyzer associated with the cells receives the laser beam after the laser beam has made the multiplicity of passes through the sample of the atmosphere and the analyzer detects concentrations of isotopes of carbon dioxide in the atmosphere in concomitance of other gas concentrations.
