| Research Abstract |
El Nino condition is important for triggering the biomass burning, but there were regional differences in the onset timing and length of dry season. The amount of the generated gaseous and particulate matters were largest in the 97/98 event which was about three times more than that of the 82/83 event. Peat bog burning made the fire period longer and produced the characteristic aerosol composition with gas to particle converted submicron particles of carbonaceous and sulfate aerosols. There was differences in the recovering speed of burnt regions depending on the distance from populated areas and vegetation types.
