The European Space Agency Soil Moisture and Ocean Salinity (SMOS) mission was launched on November 2, 2009. Providing accurate soil moisture (SM) estimation is one of its main scientific objectives. Since the end of the commissioning phase, preliminary global SMOS SM data [Level 2 (L2) product] are distributed to users. In this paper, we carried out a first(More)
In the last few years, remote sensing observations have become an useful tool for providing hydrological information, including the quantification of the main physical characteristics of the catchments, such as topography and land use, and of their variables, like soil moisture or snow cover. Moreover, satellite data have also been largely used in the(More)
Meteorological satellites provide frequent (from few hours to few minutes) observations that can be exploited to globally forecast weather conditions and, particularly, precipitation phenomena that are not rarely responsible of dangerous flooding events. Soil moisture is one of the variable involved in the hydrological cycle which plays a key role when an(More)
The paper shows the TASI-600 thermal hyperspectral sensor acquired by the Italian National Research Council — Institute of Methodologies for Environmental Analysis (CNR-IMAA) and describes some of the checks carried out during the commissioning phase. Furthermore, the first data acquired during the test-flight on hot spots of the volcanic island of(More)

In the last years satellite remote sensing applications in hydrology have considerably progressed. A new multi-temporal satellite data-analysis approach has been recently suggested in order to estimate space-time changes of geophysical parameters possibly related to the increase of environmental and hydro-geological hazards. Such an approach has been(More)
Flooding is one of the most devastating natural hazards on the Earth’s surface. Observations by sensors aboard satellites provide information that can be exploited to support the flood risk management cycle. These observations provide potential tools for improving the detection and monitoring of flooding events, particularly for those remote areas in the(More)
Satellite remote sensing has increasingly become a crucial tool for volcanic activity monitoring thanks to continuous observations at global scale, provided with different spatial/spectral/temporal resolutions, on the base of specific satellite platforms, and at relatively low costs. Among the satellite techniques developed for volcanic activity monitoring,(More)

Radio Frequency Interference (RFI) is an increasing severe problem for present and future microwave satellite missions. Transmissions from ground based systems at low microwave frequencies (especially in Cand X-bands) can contaminate with a high level of noise the remote sensed measurements (both from aircraft and satellites) at these wavelengths.
