Накратко на български
Съставът на атмосферните аэрозоли в големите градове се анализира чрез сателитни данни, измервания от самолети и симулации. Това помага за по-доброто разбиране на рисковете за човешкото здраве и влиянието на градските емисии върху климатичните промени.

Megacity Aerosol Composition by Satellite: A tool to study anthropogenic Emissions, Climate change and human Health
The MSCA-MACSECH project has contributed to tackling the problem of the composition of atmospheric aerosols, which is poorly understood and constitutes a critical gap in the assessment of risks to human health and climate change. Aerosol composition varies considerably, including organic and inorganic aerosols, but is difficult to measure directly. This project is based on the overarching hypothesis that the growth of large population centers (MPC) and the control of their pollutant emissions have a significant impact on the composition and concentration of atmospheric aerosols, and thus on climate change and human health. The overall objective was to study the aerosol composition in MPC by combining different data sources, including aircraft measurements, satellite data and numerical atmospheric simulations. The hypothesis underlying the project’s objective was that it is possible to exploit statistical relationships between aerosols and gases to obtain information on aerosol composition, for which there is no direct satellite product. Understanding the aerosol composition in MPC is essential, as these urban areas are major sources of anthropogenic emissions and human health risks.

Цел на проекта
Anthropogenic aerosol emissions from growing urban agglomerations contribute to air pollution with impacts on climate change and on human health. The composition of aerosols over megacities is partly unknown, although important to accurately understand and prevent these impacts.Satellite-based remote sensing provides a unique opportunity to spatially monitor the atmospheric composition in the lowermost troposphere. We propose to analyze complementary information on gases and aerosols in order to provide estimates of aerosol concentration at the surface with their composition, specifically over megacity regions.Current aerosol concentration and chemical composition will be assessed by combining:1) Local snapshots of aerosol concentration and composition at high spatio-temporal resolution from aircraft campaigns,2) Global retrievals of aerosol optical properties from satellite measurements, and3) Numerical atmospheric simulations.This project focuses on three regions (with different emission regulations) where scientific aircraft campaigns have been carried out, namely Europe (strict regulation), East Asia (regulation implementation in progress) and West Africa (no regulation). Based on modelling sensitivity studies, we will evaluate the benefits of emission reduction strategies on human health and anthropogenic climate change. Applied to future regulations, our methodology will provide a comprehensive analysis to advise policymakers on sustainable choices.
