Observing volcanic ash dispersion becomes critical following the abundance incidents of aircraft damage caused by volcanic ash, especially in Indonesia that located along the Pacific ring of fire. To enable an accurate forecast of volcanic ash dispersion, model PUFF offers information regarding the direction of volcanic ash dispersion based on height and size of volcanic ash. This research shows that model PUFF serves better explanation over volcanic ash advisory from VAAV Darwin and information derived from the Himawari-8 satellite. This research also further suggests for PUFF model to utilize data regarding eruption time and plume’s height provided in the interpretation result of weather radar.
