| Outline of Final Research Achievements |
At both regional and global scales, the isotopic compositions of carbon dioxide (CO2) have a marked correlation on their sink, source and transport. Therefore their isotopes have been used to investigate the processes associated with their absorption and emission of terrestrial ecosystems. Continuous measurement of stable isotope ratios of CO2 (delta 13C and delta 18O) was conducted in forest of Takayama and Fujiyoshida in Japan by using a mid-infrared laser absorption spectrometer to reveal CO2 cycle in the forest. The results suggest that the isotope ratio measurement by the mid-infrared laser absorption spectrometry can contribute to better understanding of the short-term variations of isotopes. Isotope ratios of carbon dioxide (CO2) and water vapor (H2Ov) in the near-surface air were continuously also measured for one month at urban area of Nagoya city. During a typhoon and a stable front passages in the observation period, remarkable changes of the isotope ratios were observed.
