Dust radiative forcing from reconstructed dust changes since pre-industrial times (DURF)

• To quantify the direct radiative forcing (IRFari) due to the reconstructed increase in dust since pre-industrial times
• To quantify the effective radiative forcing (ERFaci) resulting from dust interactions with warm, mixed-phase, and cirrus clouds due to the reconstructed increase in dust since pre-industrial times
• To quantify the change in the radiative forcing of anthropogenic aerosols (ERFari and ERFaci) due to interactions with dust, for instance due to dust serving as a sink for anthropogenic aerosols and precursor gases.
