| Summary: | The large-scale forest fires that occurred from August to November 2015 caused an
environmental disaster in Indonesia. Forest fires released aerosol particles that led
to reduced visibility, environmental damage, and adverse effects on human health.
These fires also emitted carbon compounds such as carbon monoxide (CO).
Consequently, simulations of smoke dispersion from forest fires on Sumatra Island
in 2015 were conducted to predict the direction of smoke spread and to compare the
performance of the WRF-Chem model against Fire Inventory from NCAR (FINN)
versions 1.5 and 2.5.
This study utilized a numerical weather prediction model that integrates chemical
parameters, namely the Weather Research and Forecasting-Chemistry (WRF-Chem)
model. This model allows for the simulation of emissions and transport of smoke
from forest fires. The initial and boundary data used in this study were sourced from
The National Centers for Environmental Prediction (NCEP) Final (FNL) for the
global atmospheric model, while the FINNv2.5 inventory was used as the input data
for forest fire emissions.
The results indicated that the direction of smoke dispersion from forest fires on
Sumatra Island was consistent with the movement observed from Himawari-8
satellite imagery using True Color RGB composites. The WRF-Chem model
simulations showed that smoke dispersion moved towards the northwest, north
northeast, and northeast, resulting in smoke spreading to Singapore. Comparing
the performance of the WRF-Chem model with the FINNv1.5 and FINNv2.5
inventories revealed that the results from FINNv2.5 were less consistent.
Specifically, the WRF-FINNv2.5 model overestimated wind speed and direction,
and underestimated temperature and relative humidity, in comparison to the WRF
FINNv1.5 model outputs. |
