摘要: The island arc volcanoes in and around Indonesia have been permanently degassing for thousands of years, thereby contributing significantly to the total emissions sulfur species that region. hot wet tropical weather conditions with high solar irradiation regular daily precipitation during season lead efficient removal oxidised sulfate by deposition. This is accumulated Indonesian peat areas, which serve as natural sponges, soaking up rain slowly releasing moisture into atmosphere dry season. When forests are drained land clearing purposes, quickly dries out becomes extremely flammable. ignited, composition burning mainly determines fire aerosol chemical microphysical properties. In this paper we investigate contribution volcanic deposition swamp areas based on numerical simulations carried a global atmospheric circulation model including tropospheric cycle. Our study suggests observed hygroscopicity elevated content aerosols due sulfur.
