Smoke aerosol transport patterns over the Maritime Continent

► Smoke transport patterns over the Maritime Continent are studied. ► Use of satellite AOD products, model assimilation and forward trajectories. ► Smoke transport pathways are closely related to the low-level atmospheric flow. ► Smoke lifetime exhibits multi-scale variability, e.g., under the effect of ENSO, MJO. ► Noticeable orographic effect on smoke transport over the MC.
