Накратко на български

Емисиите на въглероден диоксид в градовете се изследват чрез сензори и сателити, за да се разбере колко точно отделят сградите, транспортът и природата. Това помага за по-точното планиране на градската среда и проследяването на целите за климатична неутралност.

Urban carbon dioxide Flux Monitoring using Eddy Covariance and Earth Observation

Monitoring carbon dioxide emissions of urban areas is increasingly important to assess the progress towards the Paris Agreement goals for climate neutrality. The current urban emission inventories are based on bottom-up approaches that use activity data (e.g. fuel and electricity consumption statistics) and emission factors for determining carbon dioxide emissions. So far, such approaches are not systematically assessed, present consistency issues and have restricted spatial and temporal resolution. Moreover, these approaches focus on the fossil fuel emissions and neglect the biogenic components of the urban carbon cycle (i.e. plant photosynthesis/respiration, soil respiration, human respiration) which can significantly affect the urban carbon balance. The main goal of diFUME project is to provide a robust and independent methodology for mapping and monitoring the actual urban carbon dioxide flux (i.e. emissions by buildings, traffic, human-soil-plant respiration versus photosynthetic uptake) at optimum spatial and temporal scales, meaningful for urban design and planning decisions. diFUME developed a novel observation-based approach to monitor urban carbon dioxide flux in high temporal and spatial resolution. The approach combines urban in-situ Eddy Covariance measurements, Earth Observation (EO) monitoring and bottom-up modelling. The method is developed and applied in the city of Basel, Switzerland, where two urban Eddy Covariance measurement systems are available within the city centre. It is demonstrated that Eddy Covariance, combined with high resolution EO-based bottom-up modelling, can effectively resolve the spatial and temporal variability of urban carbon dioxide fluxes and quantify the relative contribution of the different emission sources (i.e. buildings, vehicles, humans, plants/soil). The approach is based on in-situ observations of the carbon dioxide fluxes, therefore can be used as an independent reference to urban inventories but also as a tool for sustainable urban planning.

Цел на проекта

Monitoring CO2 emissions of urban areas has become a necessity for sustainable urban planning and climate change mitigation. The current urban inventories are based on top-down approaches that use fuel and electricity consumption statistics for determining CO2 emissions. Such approaches present consistency issues, neglect the biogenic components of the urban carbon cycle (i.e. vegetation, soil) and have restricted spatial and temporal resolution. The main goal of diFUME is to provide a robust methodology for mapping and monitoring the actual urban CO2 flux at optimum spatial and temporal scales, meaningful for urban design decisions. diFUME will develop, apply and evaluate independent models, capable to estimate all the different components of the urban carbon cycle (i.e. building emissions, traffic emissions, human metabolism, photosynthetic uptake, plant respiration, soil respiration). An innovative interdisciplinary methodology will be introduced, combining two cutting-edge technology tools, the Eddy Covariance (EC) and the latest advances in Earth Observation (EO). EC provides continuous in-situ measurements of CO2 flux at the local scale. Previous EC applications in urban areas have provided valuable insights on the holistic understanding of the urban CO2 flux according to the source/sink distribution in the highly heterogeneous urban environment. EO offers synoptic and continuous monitoring of large areas, capable of enhanced representation of the urban cover, morphology and function. Combined use of EO and EC can provide enhanced interpretation and modelling capabilities to achieve fine scale mapping and monitoring of urban CO2 flux. diFUME methodology will be developed and applied in the case study of Basel, exploiting the unique infrastructure and long-term urban EC measurements. diFUME methodology can be transferable to any city, providing an independent toolbox for consistent urban CO2 emission monitoring, supporting sustainable urban planning strategies.
