Abstract: G60.00097 : Estimating Carbon Dioxide Emissions from Cities using In-situ and Remote Measurements on Low Cost Drones
Carbon dioxide (CO2) emissions, especially from large cities have resulted in the build-up of greenhouse gas concentrations. Existing sensor technology is too expensive for large-scale use and cannot distinguish between anthropogenic and biogenic emissions. Current platforms for measurement are limited in height and stability. In this paper, I develop a low-cost in-situ sensor for direct CO2 measurements and a spectral imaging system to remotely monitor vegetation phenology. The sensor and camera were installed on a drone for greater mobility and mathematical models used collected data to estimate emission inventories. The low-cost sensor compared favorably with state-of-the-art instruments (correlation factor = 0.99) and exhibited expected annual, seasonal and diurnal trends. The normalized difference vegetation index was computed from spectral data, and correlated with plant transpiration and carbon exchange. The predicted CO2 emission inventory for Washington DC showed a large contribution from the transportation sector. In summary, I demonstrate a methodology to measure and monitor city-wide CO2 emissions by combining low-cost in-situ measurements, multispectral imaging, small drone technology and puff modeling.
