Tracking Urban Atmospheric Pollutants using Sentinel-5P Satellite Data 事件

Tracking Urban Atmospheric Pollutants using Sentinel-5P Satellite Data arXiv:2606.02592v1 Announce Type: cross Abstract: Urban nitrogen dioxide ($NO_2$) is a key indicator of combustion-related air pollution and exhibits strong spatial and temporal variability in cities. This study presents a satellite-based framework for tracking urban $NO_2$ pollution using tropospheric column observations from Sentinel-5P/TROPOMI over Guayas Province, Ecuador. Rather than estimating surface concentrations, t
