Description:
Landfill methane contributes significantly to global climate change. However, large uncertainties exist in existing inventories due to a lack of field data. Existing data cannot provide high spatiotemporal resolution for quantifying methane emissions and evaluating methane reduction technologies. This proposed work aims to advance our knowledge in landfill methane generation and mitigation using costeffective and convenient measuring techniques.
Objective:
This proposal aligns with Research Area 1 with these specific objectives 1) Develop low-cost air quality sensors to capture methane (CH4) variation spatially and temporally. 2) Integrate sensor data from fixed locations, mobile sampling, and drone surveys to map pollution distribution and estimate emission fluxes. 3) Correlate the spatiotemporally resolved methane emission data with multiple environmental factors for evaluating methane reduction techniques.
Expected Results:
The data generated from the proposed method can reveal the dynamic and heterogeneous features of landfill methane emissions, which can facilitate our understanding of landfill methane emission characteristics. The data can also identify key drivers behind landfill methane emissions, laying the basis for evaluating and comparing control technologies. The results from this research will
lead to 3-4 peer-reviewed publications. At the same time, we will collaborate with the Frost Museum to host exhibitions to showcase the research.
