A gapless 0.05° daytime-hourly tropospheric NO 2 dataset (2019–2024) over key Asian hotspots reconstructed using physics-aware deep learning

Abstract. High-frequency continuous monitoring of tropospheric nitrogen dioxide (NO2) is crucial for assessing regional air quality and investigating photochemical dynamic evolution. Although new-generation geostationary orbit (GEO) satellites (e.g., GEMS) provide hourly observat...
