Characterization of the Spatial and Temporal Distribution of Precipitation and Hydrometeorological Disasters in Sleman, Yogyakarta

Global climate change is a serious issue resulting in variations in temperature and precipitation patterns that will have a significant impact on precipitation trends, extreme events, and hydrometeorological disasters. Hydro-meteorological disasters have had a strong impact on human societies and ecosystems. The impact of these events is expected to be exacerbated by future climate scenarios. Hydro-meteorological disasters are naturally occurring global meteorological/climatological/hydrological phenomena such as drought, floods, and typhoon, which can induce environmental damages. In this study, the methods of spatial and temporal distribution were used over Sleman regency with the dataset from 1998 - 2019 to analysed trend and anomaly precipitation up to hydrometeorological disasters. The data was used from ground truth database from Indonesia meteorological and climatological agency (BMKG) and APHRODITE (Asian Precipitation - Highly - Resolved Observational Data Integration Towards Evaluation) database. In addition, the satellite database was used by TRMM (The Tropical Precipitation Measuring Mission) from NASA and JAXA. The results showed that the ground truth and satellite database have had a strength correlation, with mean R2 is 0.68 and 0.55, for TRMM and APHRODITE. The changes of precipitation trend occur from 1998 to 2023 over Sleman regency. In addition, the hydro-meteorological disaster such as drought and floods has been analysed by Standardized Precipitation Indices (SPI), which is the severity level and number of events has various occur on sites. © 2025 Institute of Physics Publishing.
