New satellite-based low frequency microwave radiometers are being evaluated for estimating soil moisture. These include the Advance Microwave Scanning Radiometer (AMSR) instruments on the NASA Aqua satellite and the Advanced Earth Observing Satellite (ADEOS-II). Although there have been satellite instruments in space previously with these frequencies, the AMSR programs include the first ever commitments to providing a soil moisture product. As part of its algorithm selection process, the Japanese Aerospace Exploration Agency (JAXA) has been evaluating four different soil moisture algorithm approaches including a single channel method. This algorithm was evaluated here using validation data collected in Mongolia. Data quality issues, approaches to validation and algorithm performance are analyzed and discussed. Overall, the algorithm performed as expected based upon previous research.
