Haze in urban areas from peatland fires in Sumatra based on simulation using HYSPLIT

[摘要] Peatland fires which were occurred in September and October 2015 have caused air pollution in six provinces in Indonesia i.e. Riau, Jambi, South Sumatra, South Kalimantan, Central Kalimantan, and West Kalimantan. The Ministry of Health of Indonesia reported that in those six provinces, the Standard Index of Air Pollution (ISPU) reached the very dangerous level (>400) which caused public health problems. This study performed a simulation using HYSPLIT to generate haze trajectory from peatland fires in Sumatra in October 2015. Initial points for the simulation were hotspots which have occurred in order from two to five days in the same location. This study analysed haze dispersion in three urban areas: Pekanbaru, Jambi, and Palembang. The results indicated that in the period of 20-25 October 2017 haze in Pekanbaru originated from the mainstream of the Indragiri or Indragiri Hulu in which the source points were located in four villages in two sub districts: Rengat and Kuala Cenaku. In the period of 23-25 October 2017, haze from Muaro Jambi and Tanjung Jabung Timur in the Jambi Province reached Pekanbaru. In addition haze in Palembang and Jambi in the period of 18-25 October 2015 came from the three districts in South Sumatra namely Ogan Komering Ilir, Musi Banyuasin, and Banyuasin where the initial points were located in 10 villages in 9 sub districts.
