Short summary
A novel PAX-ISS method apportions aerosol light absorption to black carbon (BC), brown carbon (BrC), and the lensing effect. Field measurements reveal BC dominance, ~10 % annual BrC contribution, and a 40.0 % average lensing role in light absorption with strong spectral-seasonal variations. We provide observational indications of BrC's shortwave "blocking effect", which offsets lensing. This approach offers robust constraints for aerosol optics and climate modeling.
