This study is part of the larger study, “Production of a High-Precision, High-Resolution Global Precipitation Map Using Satellite Data (GSMaP)” led by Prof. Ken’ichi Okamoto (Osaka Prefecture University, Japan) under the “Core Research for Evolutional Science and Technology (CREST)” program of the Japan Science and Technology Agency (JST). This study is also supported by the Global Precipitation Measurement (GPM) Research Invitation by the JAXA. authors. S. Seto would like to thank Prof. Taikan Oki at the University of Tokyo for encouraging him in the study on soil moisture retrieval using TRMM data, which became a basis of this study.
