New RI-URBANS Study Develops AI-Powered Tool to Improve PM10 Source Apportionment in Cities

A team of researchers from Beijing Technology and Business University (BTBU) and the Institute of Environmental Assessment and Water Research (IDAEA-CSIC), in collaboration with European partners, has unveiled LPO-XGBoost—a cutting-edge machine learning model designed to enhance the identification of PM10 pollution sources in urban environments. By integrating traditional Positive Matrix Factorization (PMF) with a nonlinear XGBoost algorithm, the model offers a significant leap forward in air quality analysis. Tested across 21 European monitoring sites, LPO-XGBoost demonstrated high predictive accuracy (R² = 0.88), particularly excelling at pinpointing sources such as sea salt and biomass burning. This innovation is part of the RI-URBANS initiative, which aims to bridge the gap between scientific advances and practical air quality management across European cities.

New RI-URBANS Study Highlights Fine-Scale Air Pollution Mapping Across Five Major European Cities

A new RI-URBANS publication led by Karine Sartelet  quantifies intra-urban air pollution variability across five European cities (Paris, Athens, Birmingham, Rotterdam, and Bucharest) —at a resolution finer than 100 meters. Using advanced modeling techniques, the study compares both regulated (NO₂, PM₂.₅) and emerging pollutants (black carbon, ultrafine particles), quantifying their temporal and spatial variabilities. These findings highlight the importance of fine-scale mapping to better estimate population exposure and inform public health strategies. The study also offers methodological guidance to improve urban air quality models in line with upcoming EU Air Quality Directive updates.

New RI-URBANS publication evaluates Aethalometer data to optimize absorption Ångström exponent (AAE) values for eBC source apportionment

This study led by Marjan Savadkoohi evaluates the Absorption Ångström Exponent (AAE) approach for equivalent black carbon (eBC) source apportionment, addressing its strengths and limitations when distinguishing between liquid and solid fuels sources. Using a comprehensive multi-site dataset across Europe, this study recommend an optimized methodology for determining site-specific AAE values, enhancing the accuracy of eBC source attribution across diverse environments. Key Findings:  Site-specific AAE calibration significantly improves eBC source differentiation.  Constant AAE values lead to misclassification, especially in regions with high brown carbon (BrC) contributions. The integration of chemical tracers and multi-wavelength absorption data is essential for refining optical source apportionment. This research provides valuable insights for air quality monitoring, emission regulation, and climate modeling. Check out the full article here: https://doi.org/10.1016/j.atmosenv.2025.121121

New RI-URBANS Publication Explores Source-Dependent Absorption Ångström Exponent in Los Angeles

This study led by Marjan Savadkoohi examines two locations in the Los Angeles Basin—Central LA (CELA) and Rubidoux (RIVR)—leveraging comprehensive PM2.5 chemical speciation datasets and aerosol absorption coefficients measured by an Aethalometer (AE33). Through multi-time source apportionment (MT-PMF), the research uncovers factor profiles and temporal variations, providing critical insights into source-specific characteristics of fine particulate matter. By overcoming the limitations of a priori assumptions in Aethalometer optical apportionment, this work advances our understanding of urban air pollution sources and their dynamic behavior.
