abstract = "Black carbon (BC) is known to be a potential sink of carbon for
the global carbon cycle, particularly if long-term ocean stores
are reached. Fluvial transport to the oceans can occur through the
dissolution of BC in river water. Evidence from the Paraiba do Sul
river basin, Brazil suggests that river DBC concentration is
related to charcoal formed during the deforestation of the
Brazilian Atlantic Forest. However, we highlight several key
potential sources of BC to the basin that are yet to be
considered. We hypothesize that external biomass fires are a
source of BC to the basin on the basis that BC released from them
can be transported over large distances before being deposited.
This hypothesis is tested by quantifying the number of biomass
fires intercepted by trajectories en route to the basin using the
HYSPLIT model and a MODIS burned area dataset. We then create a
Black Carbon Fallout Index (BCFI) which is rationalized by our
assumption that atmospheric BC delivery to the basin is
proportional to the number of interceptions of air masses en route
to the basin. Our results suggest that the BC fallout from air
masses reaching the basin in the dry season can explain 50% of the
variance in DBC measured in the PSR channel during a subsequent
collection campaign (p<.001). Spatial and temporal variations in
the supply of BC to the basin throughout the dry season may in
part be linked to the fires associated with the cultivation of
sugarcane in southeast Brazil.",
