Abstract

Every year, forest fires occur in the Klias - Binsulok peat swamp forest. These peat forest fires release large amounts of carbon, PM1O, NOx, and SOx into the atmosphere. This study was done to model the dispersion of these particle when they are emitted into the atmosphere. The main objectives for this study is to model the dispersion of PM1O and NOx, analyse the dispersion pattern in regards to the meteorological conditions of that time and also to determine the exposure concentrations of PM10 and NOx along the simulation period. In this study, the HYSPLIT_4 (Hybrid Single Particle Lagrangian Integrated Trajectory Version 4) is used to model the dispersion of PM 10 and NOx towards the surrounding area. Throughout the whole study, a total of 6 models were run. This includes 2 trajectory models and 4 concentration models. All models were displayed in two formats, one a 2-D map and the other a GIS map provided by Google Earth. Modelling was done at 2 periods, March and August 1998. Meteorological data used were from the NOAA Reanalysis data. Overall, the study revealed dispersion patterns that were expected. The monsoon winds showed a direct effect on the direction of dispersion, thus confirming that the meteorological condition can directly effect the dispersion pattern. Exposure concentrations were also determined for PM10 and NOx along the simulation period.
