Abstract

The water resources of Bintan Island is limited and dependent on rainfall variability. The exposed location of Bintan small island make this island particularly vulnerable to natural disaster expecially drought. The meteorological drought related information is required for the water resources management of Bintan island. This article provides calibration of CHIRPS data. The ground-based rainfall observation data is used for CHIRPS data calibration. The Drought analysis used CHIRPS rainfall data, and ground-based observation data was carried out using the Standardized Precipitation Index (SPI). The results showed that the data set performed well in assessing drought years (1982, 1997, and 2015). The statistical Z test results showed that the CHIRPS data and ground-based observation data were not showing significantly different values. This study concludes that CHIRPS data is valuable for drought monitoring tools in Bintan island, where the ground-based observation rainfall data is very limited.
