| Research Abstract |
This research project aims to investigate the strategies of the use of tunable diode laser spectrophotometer (TDLS) for the understanding of trace gas dynamics in the forest ecosystem. Trace gases such as CH_4 are important greenhouse gases and their dynamics should be understood, although the information about source/sink and their dynamics is very limited in the forest ecosystems. We established the systems for measuring 1) chamber scale CH_4 emission or absorption rate from each compartment of the forest ecosystem such as unsaturated soil, foliage, stem, 2) canopy CH_4 flux with REA method, and 3) vertical profile of CH4 concentration, and continued the monitoring for more than one year.
