New RI-URBANS Study Maps High-Resolution Source-Resolved PM2.5 Exposure in Athens

A new publication from the RI-URBANS community presents a novel approach to simulate source-resolved PM2.5 air pollution at 1 × 1 km² resolution, applied in Athens, Greece. Using the PMCAMx model and PSAT  algorithm, the study quantifies both local and regional sources of PM2.5 and estimates human exposure to different local and regional sources based on population data.
          Key findings:
  • Residential biomass burning and transportation are top local contributors.
  • High-resolution modelling reveals spatial detail missed by coarser grids.
  • PM population exposure is influenced by local sources more than PM levels
  • Supports better-informed urban air quality and public health policies
