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, the methodology emphasizes robust distributional metrics, including the median and upper-tail percentiles ($P_{90}$, $P_{95}$, and $P_{99}$), to characterize background cond
The increasing availability and resolution of satellite earth observation data, combined with advances in AI, enable more precise environmental monitoring technologies.
This study demonstrates a sophisticated application of satellite data for environmental tracking, which can inform urban planning and public health policies globally without relying on ground sensors.
The ability to track specific urban pollutants like NO2 using satellite data alone changes how cities and governments can monitor, understand, and potentially regulate air quality.
