PADNet global land daily AOD, fAOD, cAOD and FMF dataset from GCOM C SGLI observations 2018 to 2024

This dataset provides a global land size resolved aerosol product generated by the Physical scaled AOD Decomposition Network, PADNet, for 2018 to 2024. The dataset provides aerosol optical depth (AOD), fine mode aerosol optical depth (fAOD), coarse mode aerosol optical depth (cAOD) and fine mode fraction (FMF) at 0.04° × 0.04° spatial resolution. PADNet integrates multi angular, multi spectral and polarimetric observations from GCOM-C/SGLI with aerosol physical consistency constraints to retrieve both total aerosol loading and aerosol size partitioning over land. By separating AOD into fine mode and coarse mode components, PADNet provides a physically informed observational dataset for diagnosing aerosol regimes that are not resolved by total aerosol optical depth alone. The dataset is intended for research on aerosol variability, size resolved aerosol climatology, compound fine and coarse aerosol extremes, aerosol source attribution, land atmosphere interactions and climate related aerosol risk. It provides an observation constrained baseline for global land aerosol studies and can also be used for model evaluation, machine learning applications and future projection studies.
