Abstract
The Advanced Microwave Scanning Radiometer 2 (AMSR2), a follow-up microwave sensor to the AMSR for Earth Observing System (AMSR-E), was launched on the Global Change Observation Mission 1 – Water (GCOM-W1) satellite in May 2012. It is as yet unclear if instrumental improvements in AMSR2 over AMSR-E have led to better soil moisture (SM) estimates, especially since there is no overlapping period of data between the sensors. This study focuses on comparing the results of AMSR2 and AMSR-E SM over Australia, distinguishing four Köppen climate zones to determine if AMSR2 is better than AMSR-E. This is achieved by selecting two year-long comparative time periods from the operating periods of AMSR-E..

The authors are grateful to all who contributed to the data sets used in this study. We would also like to thank the editor and three anonymous reviewers for their valuable comments on the manuscript. The AMSR2 and AMSR-E LPRM data were produced by Richard de Jeu (VUA), Robert Parinussa (UNSW), and colleagues at NASA. The AMSR2 LPRM V001, AMSR-E LPRM V002, and MERRA-L SM datasets were downloaded from the NASA Goddard Earth Sciences Data and Information Services Center (GES-DISC). The most recent AMSR2 LPRM SM datasets were personally provided by Dr. Parinussa.
