SWI daily images are produced from EUMETSAT ASCAT-25km SSM product in orbit format and include a quality flag indicating the availability of SSM measurements for SWI calculations. Soil moisture is a key parameter in numerous environmental studies including hydrology, meteorology and agriculture. In addition to Surface Soil Moisture (SSM), information on the moisture condition within the underlying soil profile is of interest for different applications. Soil moisture in plant root zone can be estimated by an infiltration model using information on surface soil moisture and soil characteristics. The data are available over the globe at the spatial resolution of 0.1° and with the temporal extent from January 2007 to present. This product is first designed to fit the requirements of the Global component of the Copernicus Land service. It can be also useful for all applications related to environment monitoring. The research leading to these results has received funding from the European Community's Seventh Framework Program (FP7/2007-2013) and is maintained through the Copernicus European Earth monitoring program, more particularly through the Global component of the Copernicus Land service.

The algorithm is based on a two-layer water balance model to estimate profile soil moisture from SSM retrieved from scatterometer data. The remotely sensed topsoil represents the first layerand the second layer extends downwards from the bottom of the surface layer. In this model, the water content of the reservoir layer is described in terms of an Index, which is controlled only by the past soil moisture conditions in the surface layer in a way that the influence of measurements decreases by increasing the time. The SWI processing algorithm uses near-real-time ASCAT-25km SSM product as input to generate daily global SWI images. Therefore a computational adaption of SWI algorithm has been made based on a recursive formulation. In this method, a gain factor is introduced that relates the past SWI measurements to the current measurements. SWI images are calculated for eight different T values (1, 5, 10, 15, 20, 40, 60, 100) together with the respective quality flags. The SWI quality flag is a parameter related to the number of available SSM measurements used for calculation of SWIT at time t. It is calculated also by using a recursive formulation and expressed in percentage after normalization.
