Integrating Long-Term Mobile Measurements with Geospatial Modeling for On-Road PM2.5 Assessment in Hong Kong
Fixed monitoring networks characterize urban PM2.5 trends but cannot resolve variation among individual roads and transport corridors. This study developed and evaluated a two-stage framework integrating long-term mobile measurements with satellite-assisted geospatial modeling to estimate on-road PM2.5 at 30 m resoluti...
