【 摘 要 】

The availability of various satellite rainfall data potentially be used in monitoring meteorological droughts. In this study, products from the NCEP-CFSR (National Centers for Environmental Prediction Climate Forecast System Reanalysis) were analyzed to estimate meteorological drought in the Citarum Watershed, West Java, Indonesia. Assessment was carried out using NCEP-CFSR data from 1988 to 2013 and was applied to meteorological droughts using the SPI (Standardized Precipitation Index) index. The results showed that rainfall products from the NCEP-CFSR were not recommended to use in meteorological droughts because of the low correlation values of around 33%, MAE (Mean Absolute Error) 17.88 and RMSE (Root Mean Square Error) 22.73. This research can be utilized as a reference to assess rainfall products from better satellite data in the future to monitor meteorological droughts.
