A comparison of atmospheric aerosol absorption properties from the MERRA-2 reanalysis with AERONET

Supplementary material to "Long-term Variability in Black Carbon Emissions Constrained by Gap-filled Absorption Aerosol Optical Depth and Associated Premature Mortality in China"

“…However, some studies suggested that MERRA-2 may overestimate the dust lightabsorption contribution due to excessive local dust emissions and transport of Asian dust (Bakatsoula et al, 2023) S3b), much lower than that of MERRA-2. To avoid the influence from BrC, we adopted AAOD at the wavelength of 865 nm obtained in Test 1.…”
