To estimate/predict the amount of air pollutants from the forest fires emission under the
user event and the other factors (meteorological characteristic). Which may affect the amount for emission of air pollutants. The data will receive from the Royal Forest Department of Thailand. Using of FEPS model follow by the user’s guide. This is a limitation of this research project .However, considering the different factor make varies emission. The resulting emission due to meteorological data. So, input data into the FEPS model is very important. Project is to find out the amount of particulate matter (PM-10) emit from forest fires. Preparing Emission Factor and Emission Inventory database of the Forest Fires. The information obtained from the analysis is particularly useful when the data has been developed and applied educational opportunities in the other area in the future.
