Discussion

Analysis reveals significant differences in NO2 observations from GOME-2C and TROPOMI, highlighting satellite limitations.

Significant differences in NO2 observations were found between GOME-2C and TROPOMI, affecting pollution trend analysis.
In East Asia, urban areas showed the highest NO2 concentrations, particularly in winter with a noted accumulation.
Observational analysis compared satellite-derived NO2 with ground-based measurements from Pandora across various regions.
These findings suggest limitations of fixed-time satellites, stressing the need for improved geostationary monitoring.

Li et al. (2025) studied this question.
