Spatial and temporal variability of urban fluxes of methane, carbon monoxide and carbon dioxide above London, UK
We report on more than 3 years of measurements of fluxes of methane (CH4), carbon monoxide (CO) and carbon dioxide (CO2) taken by eddy-covariance in central London, UK. Mean annual emissions of CO2 in the period 2012–2014 (39.1± 2.4 ktons km−2 yr−1) and CO (89± 16 tons km−2 yr−1) were consistent (within 1 and 5 % respectively) with values from the London Atmospheric Emissions Inventory, but mea...

متن کاملCarbon dioxide and methane fluxes from an intermittently flooded paddy field
To assess the role of floodwater in controlling the exchanges of CO2 and CH4 from soil, floodwater and the canopy in intermittently flooded rice paddies, an intensive field campaign (IREX96) was conducted in Japan during August 1996. Eddy covariance was employed to measure fluxes of heat, water vapor and CO2. The flux-gradient method was used to determine CH4 fluxes from measured profiles of CH...
متن کاملMethane and carbon dioxide fluxes and source partitioning in urban areas: the case study of Florence, Italy.
Long-term fluxes of CO(2), and combined short-term fluxes of CH(4) and CO(2) were measured with the eddy covariance technique in the city centre of Florence. CO(2) long-term weekly fluxes exhibit a high seasonality, ranging from 39 to 172% of the mean annual value in summer and winter respectively, while CH(4) fluxes are relevant and don't exhibit temporal variability. Contribution of road traf...
متن کاملLocal-scale fluxes of carbon dioxide in urban environments: methodological challenges and results from Chicago.
Much attention is being directed to the measurement and modeling of surface-atmosphere exchanges of CO2 for different surface types. However, as yet, few measurements have been conducted in cities, even though these environments are widely acknowledged to be major sources of anthropogenic CO2. This paper highlights some of the challenges facing micrometeorologists attempting to use eddy covaria...
