| Summary: | A research on Black Carbon (BC) concentration in the Global Atmosphere Watch
Bukit Kototabang (GAW BKT) associated to biomass burning for 2014-2018. BC
has an effect to the climate called Direct Radiative Forcing (DRF). Biomass
burning is represented by hotspot number from Visible Infrared Imaging
Radiomater Suite (VIIRS). BC source is tracked with a backward trajectory
analysis. Monthly rainfall analysis is done for seasonal pattern of biomass burning.
DRF is from AEROgui atmosphere optical model and SMARTS radiative transfer
model.
Biomass burning is the source of BC in GAW BKT since BC concentration is highly
correlated with hotspot count (R2=0.83) and confirmed by the backward trajectory
analysis. Hotspots show monsoonal pattern where the 90th percentile of hotspot
concentration fell on dry season. BC DRF on the atmosphere is 0.003 W m-2 to
0.423 W m-2 which means radiation absorption by BC. There is no clear DRF
pattern related to hotspot count since there is only few ideal condition when DRF
can be estimated.
