In this study, four recently published soil-moisture datasets are comparedwith in-situ observations from the REMEDHUS monitoring network located in the semi-arid part of the Duero basin in Spain.The remotely sensed soil-moisture products are retrieved from (1) the Advanced Microwave Scanning Radiometer (AMSR-E), whichis a passive microwave sensor on-board NASA’s Aqua satellite, (2) European Remote Sensing satellite (ERS) scatterometer, whichis an active microwave sensor on-board the two ERS satellites and (3) visible and thermal images from the METEOSAT satellite.Statistical analysis indicates that three satellite datasets contribute effectively to the monitoring of trends in surfacesoil-moisture conditions, but not to the estimation of absolute soil-moisture values. These sensors, or rather their successors,will be flown on operational meteorological satellites in the near future. With further improvements in processing techniques,operational meteorological satellites will increasingly deliver high-quality soil-moisture data. This may be of particularinterest for hydrogeological studies that investigate long-term processes such as groundwater recharge.
