Research Abstract |
Fluxes and concentrations of carbon dioxide isotope compositions provide information about not only carbon balance but also ecosystem physiological processes and their response to environmental variation. For continuous measurement of carbon dioxide isotopic composition over various time-scales using a tunable diode laser spectrometer (TDLS), the performance of a TDLS was tested. Using this TDLS, we developed portable carbon isotope observation system, and continuously observed carbon isotopic composition of carbon dioxide in a field. The carbon isotopic composition of the atmospheric carbon dioxide was fluctuated according the changes of carbon dioxide concentration and fluctuations of the carbon isotope signal from soil respired carbon dioxide was not detected, although Keeling plots to estimate isotope signal from the soil were very sensitive and the results were very scattered especially in winter.
