Global Daily fAOD and cAOD Dataset (2001–2024) Derived from PRISM-DNN

This dataset provides global daily fine-mode aerosol optical depth (fAOD) and coarse-mode aerosol optical depth (cAOD) from 2001 to 2024 at 0.5° spatial resolution, retrieved using the PRISM-DNN model. PRISM-DNN is a deep learning framework for pixel-wise aerosol inversion that integrates multi-source satellite data with advanced spatiotemporal modeling. The product offers high spatial and temporal resolution and supports long-term air quality and climate research.
