| Outline of Final Research Achievements |
In October 2010, Mt. Merapi, a remarkably active volcano locating in the center of Java Island, triggered large-scale explosion. This brought severe damage, including ash fall and air pollution due to air pollution gases, in Yogyakarta City, locating 30 km south of Mt. Merapi. Generally, air pollutions are caused by the complex of natural sources such as volcanic activities and transport from continents or oceans by winds and artificial sources such as fossil fuel combustion and automobiles.
The classification of aerosol sources in Yogyakarta was carried out by using Positive Matrix Factorization(PMF) analysis. 5 sources such as secondary generated aerosol from air pollution gases, sea salt, biomass combustion, fossil fuel combustion and volcanic soil were classified.
