Abstract

The temporal variations of methene emission and its relation to air temperature were investigated in Upo-swamp during June 2007 through July 2008. To perform this study, the methene emission and air temperature were observed using the buoy-type chamber and automatic weather observation system(AWS), respectively. The methene emissions were much during summertime(June~August). The maximum value(about 73.4 mg/$m^2$/hr) appeared at August. The emission diminished by degrees after August. The methene emissions were fewer from September to May of the following year. The peak value(73.4 mg/$m^2$/hr) of the methene emission is very much compared to that of rice pappy field known as about 28.7 mg/$m^2$/hr.
