| Outline of Final Research Achievements |
Global surface water maps were produced based on spaceborne microwave radiometers’ measurements. Initially, the ratio of surface covered by water is estimated for a 0.1 by 0.1 degrees grid in the period of 2013 to 2018 all over the world (except for regions higher than 60 degrees latitude north and south). Next, the ratio is estimated for a 1.5 by 1.5 seconds grid in the period of 2015 to 2019 all over Japan (except for some islands). The inundation by river flood and artificial water surface such as paddy field are separated. The second product reproduces the inundation caused by heavy rainfall by Typhoon Hagibis in 2019 successfully.
