Aircraft data for INFLUX

Urban environments are responsible for more than 70% of energy related global fossil fuel emissions, and this figure is expected to increase as cities continue to expand and grow in the coming decades. Measurement approaches must be in place to verify compliance to future control and mitigation strategies. The Indianapolis Flux experiment (INFLUX) is a collaborative effort that aims to develop, assess and improve methods for quantifying urban greenhouse gas emissions, focusing on the city of Indianapolis. Data posted in this site correspond to several 2011 flight experiments in the air shed of Indianapolis to quantify the anthropogenic CO2 and CH4 enhancement downwind of the city. Using these data and an aircraft-based mass balance approach (Mays et al., 2009), we quantify the citywide CO2 and CH4 emission flux of Indianapolis, assess the uncertainties of the method, and suggest improvements in the experimental flight plan to minimize these uncertainties (Cambaliza et al., 2013).
