A gapless 0.05° hourly tropospheric NO2 dataset (2019–2024) over key Asian hotspots reconstructed using physics‑aware deep learning

Overview This repository provides a gapless, 0.05° high-resolution, hourly tropospheric nitrogen dioxide (NO2) vertical column density (VCD) dataset covering representative hotspots in Asia. The dataset was reconstructed using a physics-aware deep learning framework. Data Features Variable: Tropospheric NO2 Vertical Column Density (VCD) Spatial Resolution: 0.05° × 0.05° Temporal Resolution: Hourly (daytime) Temporal Coverage: 2019-01-01 to 2024-12-31 Spatial Coverage: Key Asian regions (North China Plain-NP, Sichuan Basin and surroundings-CC, Korea and Japan-KJ, Northern India-NI) Unit: Pmolec/cm2 (10^15 molecules/cm2) The data are organised as hourly files named YYYYMMDD_HH.nc, and HH refers to the hour time in UTC. It is recommended to use the daytime data. The nighttime data is experimental.
