The project effort includes both the bottom-up (upscaling) and top-down (downscaling) approaches to quantify
the vertical fluxes of CO2 emissions into the atmosphere, attributed to four components of the urban carbon cycle:
building, road transportation, human body, and vegetation and soils. These sub-models are derived from data sources,
such as weather stations, remote sensing techniques, big data analysis, volunteered geographic information, and in situ
CO2 measurements and then aggregated to city (0,5 - 1km) and neighborhood (100 - 50 m) scales.
Tower-based continuous measurement of CO2 fluxes, conducted by the Chair of Climatology in two neighborhoods in Berlin,
creates an excellent opportunity to validate and compare measured and modelled emissions. Once validated, the carbon mapping
model can be adequately applied to any city in the world, more specifically to areas where estimated CO2 emissions data are insufficient.
The project will provide a comprehensive dataset of CO2 emissions in three cities, other than Berlin: Lisbon (Portugal), Curitiba and Rio de Janeiro
(Brazil) at street, building, neighbourhood and city scales, using the CO2 emission-based mapping model.
This research project is financed by the Coordenaçao de Aperfeiçoamento de Pessoal de Nivel Superior - Brazil (CAPES) and the Alexander von Humboldt
Stiftung/Foundation. Interdisciplinary collaborators of the project are experts from the Federal University of Curitiba, Rural Federal University of
Rio de Janeiro (Brazil), and the Institute of Geography and Spatial Planning (IGOT, University of Lisbon).
