  1. Interannual and Seasonal Variations of Coastal Heavy Rainbands (CHeRs) along Sumatera and Borneo Island Based on 9 Years GSMaPand 14 Years TRMM (3B43) Datasets

  2. Data Monthly Global Satellite Mapping of Precipitation (GSMaP) MWR dataset (1998-2006), with Spatial Resolution 0,25⁰ x 0,25⁰ (http://sharaku.eorc.jaxa.jp/GSMaP_crest/html/data.html) Monthly Tropical Rainfall Maesurement Mission (TRMM) 3B43 dataset (1998-2011) with Spatial Resolution 0,25⁰ x 0,25⁰ Monthly Nino 3.4 Index (5°North - 5 °South; 170°-120° West) dataset (1998-2006) (http://www.cpc.noaa.gov/data/indices) Monthly Dipole Mode Index (DMI) dataset (1998-2006) derived from NOAA OI SST data (http://www.jamstec.go.jp/frsgc/research/d1/iod/)
