AB: This research focuses on an integrated monitoring of land surface water with AMSR-E and MTSAT. The combination of optical and passive microwave sensors and innovative processing methodologies are used to measure river discharge, floods, droughts, watershed runoff, agriculture activities and wetland mapping over time. A time series of analysis on rice crop cultivation and flooding event was conducted on vegetation and inundation condition with MTSAT derived indices and those of AMSR-E. It was found that AMSR-E captures a salient points on rice cropping phenology more precisely than MTSAT because it is not affected by cloud contamination. A all-weather type monitoring with high frequency can be effective especially on inundation condition in wet season along with MTSAT data with high spatial resolution. This system is running as fully operational and can be accessed at http://webmodis.iis.u-tokyo.ac.jp/LSW/.
