抄録

A transportable device based on absorption spectrometry was constructed and the atmospheric methane concentration over a rice paddy was measured. An open optical path of 50 m length was employed along with a PbSnTe diode laser. Diurnal change of methane concentration was recorded in association with meteorological parameters. Feasibility was proven for practical application to in situ study of atmospheric methane.
