Map of Cambodia and location of rain gauges with their symbols (N1–N7 in yellow for northern stations, S1–S14 in blue for southern stations, M1–M6 in green for mountainous stations, and C1 in purple for the coastal station). Four white circles show the excluded stations for the analysis due to frequent missing data. Station S7 is equipped with an AWS. The color shades indicate the elevation, and the white hatched area around the Tonle Sap Lake is its seasonal expansion area where it is under water from the middle of the rainy season (around August) to the beginning of the dry season (around December). The base map is adapted from The Atlas of Cambodia (Save Cambodia’s Wildlife 2006)
