Fig. 4: The spatial distributions of dust shortwave (SW) direct radiative effect.

a–c the Default experiment of OPAC scheme, (d–f) New-avg experiment of updated scheme and their dust shortwave radiation effect at the TOA, ATM and SFC respectively. g–i Difference between the two sets of experiments. Significant differences have occurred at the TOA, where radiative effect exhibits sign reversal. Concurrently, atmospheric absorption is substantially attenuated.
