Downscaling Tool for City Emission Inventories

This report is a technical document that describes the development of a downscaling tool for constructing city emission inventories, as part of the EU PAUL project. The report outlines the importance of city emission inventories in understanding greenhouse gas and air pollutant emissions, which are critical for informed decision-making in urban environments. It provides a step-by-step guide for city stakeholders to estimate city-wide emissions, detailing the methodology used to enhance spatial resolution and detail in emissions data. The document explains the necessity of local knowledge and datasets for improving accuracy, while focusing on a generic European approach. The methodology section elaborates on the input data, including the CAMS-REG European emission inventory and the use of proxy data for various emission sectors. It also discusses the process of defining output domains and the significance of high-resolution data for effective policy support and atmospheric modeling.
