A new value-added and long-term aerosol component global dataset derived by GRASP/AERONET

Aerosol component retrievals at 899 AERONET sites from 1993 to 2021 are publicly available for download.Black carbon (BC) in fine mode indicates wavelength-independent strong absorption.Brown carbon (BrC) in fine mode indicates wavelength-dependent absorption.Coarse-mode absorbing insoluble (CAI) indicates coarse mode wavelength-dependent absorption mainly representing iron oxides in dust.Coarse-mode non-absorbing insoluble (CNAI) component indicates coarse non-absorbing dust and aged carbonaceous aerosols.Fine-mode non-absorbing insoluble (FNAI) component indicates fine non-absorbing dust and organic carbon.Quality (*) indicates the aerosol component retrievals with high uncertainty for the low aerosol loading (AOD_440 nm ≤ 0.2).Quality (**) indicates the aerosol component retrievals with medium uncertainty for the aerosol loading (0.2 Quality (***) indicates the aerosol component retrievals with low uncertainty for the aerosol loading (0.4 Users are required to fully cite the relevant publications when using this dataset.
