| Outline of Final Research Achievements |
A new technique for measuring atmospheric carbon monoxide (CO) flux near boundary layer has been developed, because CO is a major atmospheric pollutant in the urban atmosphere. Since the typical concentration of CO in the urban atmosphere is about several hundreds ppb and below, we utilized a semiconductor laser-based high-sensitive spectroscopy technique for in-situ and real-time detection of atmospheric CO. The laser spectrometer has been combined with a relaxed eddy accumulation (REA) equipment that has also been developed in this study, in which the REA approach is well-known as one of the major micrometeorological techniques for measuring the ecosystem CO2 flux. We made a performance test of our system by observations of urban air in Sakai, Osaka. This study has successfully revealed temporal variations of CO flux in the urban atmosphere.
