Abstract—Landfill gas (LFG) emissions were measured in a landfill in tropical conditions in Malaysia to investigate seasonal variations in methane (CH₄) and carbon dioxide (CO₂) emissions. The study results showed that CH₄ and CO₂ emissions were ranged from 0 to 1,602 g m^-2 d^-1 and 5 to 2,753 g m^-2 d^-1 during wet and dry seasons, respectively, and higher CH₄ and CO₂ emissions were found during the wet season than in the dry season. It is concluded that special consideration must be given to landfill cover soil in order to enhance CH₄ oxidation and, thereby, reduce CH₄ emissions.

Index Terms—LFG emission, landfill, methane emission, seasonal variation.
