    (Elsevier, 2020) Sheau Tieh Ngai; Liew Junenga; Fredolin Tangang; Jing Xiang Chunga; Ester Salimuna; Mou Leong Tan; Siti Amalia
    The quantile mapping (QM) bias correction algorithm was applied to bias-correcting the daily rainfall over the Malaysia based on the APHRODITE gridded observed dataset. The quality of the bias correction in reducing the biases of regional climate models in frequency (FREQ), mean intensity (SDII) and 90th percentile (Q90) of the daily rainfall was assessed.

    SouthEast Asia HydrO-meteorological droughT (SEA-HOT) framework: A case study in the Kelantan River Basin, Malaysia
    (Elsevier, 2020) Mou Leong Tan; Liew Juneng; Fredolin T. Tangang; Narimah Samat; Ngai Weng Chan; Zulkifli Yusop; Sheau Tieh Ngai
    A holistic framework was introduced to project the potential hydro-meteorological droughts of the Kelantan River basin, Malaysia. The framework integrates the multi-model high-resolution climate projections of the Coordinated Regional Climate Downscaling Experiment – Southeast Asia (CORDEX-SEA) and the widely applied Soil and Water Assessment Tool (SWAT) model. The quantile mapping approach was used to reduce the biases in the CORDEX-SEA projections before applying into SWAT. The SWAT-simulated standardized streamflow index (SSI) was validated with observed data to check the capability of SWAT in drought estimation.
