Fine dust drives short-wave direct radiative effect cooling across atmospheric levels, producing consistent negative radiative forcing at the surface and top of the atmosphere.
Fine dust contributed nearly 50% of total direct radiative effect at both boundaries, while asymmetry factor differences exceeding 0.1 magnified model discrepancies.
Radiative transfer simulations using the Global Atmospheric Model reveal component-specific optical properties, highlighting that neglecting fine dust skews climate modeling.
