Fig. 5. Bounding the light absorption of WS-BrC in the South Asian outflow.
The decay/bleaching of the mass absorption cross section at 365 nm (MACWS-BrC 365) (vertical bars in black) of WS-BrC between source-to-receptor sites in the South Asian outflow is shown. The first-order rate of bleaching (k) is constrained (using Eq. 1) for the over-ocean transport of the BrC plume between BCOB and MCOH (solid line). The transport times of BrC plume evolution (horizontal bars in red) are calculated from BCOB as forward trajectories to MCOH and BTs to Delhi using the HYSPLIT model. The AOD at 550 nm is shown in combination with distance from BCOB. The AOD was obtained from NASA MODIS for the SAPOEX-16 campaign period.
