摘要：

Eddy covariance (EC) flux measurements of CO2, CH4 and particles in densely urbanized area in Florence are reported, and partitioned into emission categories. CO2 fluxes are a net source to the atmosphere, with small inter-annual variability and high seasonality. CH4 fluxes represent about 8% of CO2-equivalent emissions, and do not exhibit significant seasonality. Heating and road traffic account for 68% and 32% of observed CO2 emissions, respectively, and for 14% of CH4 emissions, while gas network leakages are responsible for the residual. Particle fluxes exhibit a pronounced weekend decrease, highlighting that the main contribution to emissions comes from road traffic. (C) 2013 The Authors. Published by Elsevier Ltd.
