Soil moisture plays an important role in the global water cycle and is used in the estimation of drought, to determine flooding .hot-spots. as an input for crop yield monitoring, for flux and hydrological modelling and climate change assessment. Availability of reliable and frequent soil moisture data on a dynamic basis is essential for hydrometeorological applications and is an issue for weather and agricultural services. Dedicated EO missions and sensors allow retrieval of information about the topmost soil layer moisture content.
