Data filename describtions

LLiGMD2022_dust_quantity_"casenames".nc: dust quantities including dust aerosol optical depth, deposition fluxes (wet, dry, and total), and burdens

LLiGMD2022_dust_DRE_"casenames".nc: dust direct radiative effect at the top of the atmosphere under all-sky conditions

Note dust quantities and direct radiative effects from EXP03 and EXP04 are rescaled in Li et al. (2022), but this dataset cotains unscaled numbers.

Descriptions of variables

toaforcingnt (W/m2): net (SW+LW) direct radiative effect

AODDUST (unitless): dust aerosol optical depth at the visible band centered at 0.53 µm

dst_aSF (Kg/m2/s): surface dust emission rate

dst_ttDDF (Kg/m2/s): dry deposition rate of dust aerosol

dst_ttDep (Kg/m2/s): total deposition (dry+wet) rate of dust aerosol

dst_ttSFWET (Kg/m2/s): wet deposition rate of dust aerosol

dust_burden (kg/m2): dust burden
