The presence of liquid water at the base Martian polar caps has long been suspected but not observed. We surveyed Planum Australe region using Mars Advanced Radar for Subsurface and Ionosphere Sounding, a low-frequency radar on Express spacecraft. profiles collected between May 2012 December 2015, contain evidence trapped below ice South Polar Layered Deposits. Anomalously bright subsurface reflections were found within well-defined, 20km wide zone centered 193°E, 81°S, surrounded by much...
Chang'e-3 (CE-3) has been the first spacecraft to soft land on moon since Soviet Union's Luna 24 in 1976. The arrived at Mare Imbrium December 14, 2013, and same day, Yutu lunar rover separated from lander start its exploration of surface subsurface around landing site. was equipped, among other instruments, with two penetrating radar systems having a working frequency 60 500 MHz. radars acquired data for about weeks while slowly moving along path 114 m. At navigation point N0209, got...
Abstract The study of geothermal systems is nowadays a topic great importance because the huge amount energy that could be converted in electricity for human consumption from such sources. Among various geophysical methods employed to reservoirs, magnetotelluric (MT) method capable reveal internal structures subsurface and interpret geological electrical resistivity. We present first 3D resistivity model La Palma (Canary archipelago, Spain) obtained dataset 44 broadband soundings distributed...

The data has been generated using hybrid modelling approach integrating hydrological conducted with physically-based GEOtop model, preprocessing meteorological data, assimilation in-situ measurements Earth Observation products enhance quality model estimates. A rigorous...
Snow is a critical component of the mountain cryosphere and plays significant role in shaping hydrology snow-fed basins during summer months. The snowpack serves as vital water reservoir, accumulating wintertime gradually releasing melt season, to sustain downstream demands. highly sensitive climate change, particularly low- mid-elevation regions like European Alps.We present an analysis long-term (30 years) dataset snow equivalent (SWE) Po River district, Italy, which partially covers...
Abstract Ground‐penetrating radar (GPR) is a well‐established geophysical terrestrial exploration method and has recently become one of the most promising for planetary subsurface exploration. Several future landing vehicles like EXOMARS, 2020 NASA ROVER, Chang'e‐4, to mention few, will host GPR. A GPR survey been conducted on volcanic deposits Mount Etna (Italy), considered good analogue Martian Lunar terrains, test novel methodology subsoil dielectric properties estimation. The...
We propose a strategy to evaluate the performance of radar sounder for subsurface exploration Europa icy crust and, in particular, possibility detect liquid water at base ice shell. The approach integrates information coming from experimental measurements dielectric properties materials, thermal models related different crustal scenarios, and numerical simulations signal propagation. response has been evaluated terms cumulative attenuation, signal-to-noise ratio (SNR), reflectivity. Our...
The use of the ground-penetrating-radar (GPR) technique to estimate snow parameters such as thickness, density, and water equivalent (SWE) is particularly promising because it allows for surveying a large area in relatively short amount time. However, this application requires an accurate evaluation physical retrieved from radar measurements, which estimating each quantity involved computation along with its associated uncertainty. Conversely, uncertainties are rarely reported GPR studies,...
Two anhydrobiotic strains of the cyanobacterium Chroococcidiopsis, namely CCMEE 029 and 171, isolated from Negev Desert in Israel Dry Valleys Antarctica, were exposed to salty-ice simulations. The aim experiment was investigate cyanobacterial capability survive under sub-freezing temperatures samples simulating environment icy worlds. two mixed with liquid solutions having sub-eutectic concentration Na2SO4, MgSO4 NaCl, then frozen down different final (258 K, 233 K 203 K) various...
Liquid water was present on the surface of Mars in distant past; part that is now ground form permafrost and heat from molten interior planet could cause it to melt at depth. MARSIS (Mars Advanced Radar for Subsurface Ionosphere Sounding) has surveyed Martian subsurface more than fifteen years search evidence such buried detection liquid can be stated as an inverse electromagnetic scattering problem, starting echo intensity collected by antenna. In principle, problem modelled a normal plane...

Abstract. Snow water equivalent is a fundamental parameter for hydrological and climate change studies but its measurement usually time consuming destructive. Electromagnetic methods could be valid alternative to conventional techniques, being fast non-invasive. In this work we analyze the reliability of combined GPR/TDR method estimate snow thickness equivalent. To GPR accuracy perform calibration test where measured predicted radar data are compared in terms two-way travel time....
In water resources management, predictive services are essential to support sustainable planning and operations over a range of time scales, from the short term (days) medium (seasons) long (years decades). Current forecasting tools mainly address availability (i.e., quantity), with limited practical applications for quality. Within framework project called “Strumenti di monitoraggio e previsionali sullo stato QUalità delle Acque Superficiali” (SQUAS; founded by...
In Europe, the majority of precipitation during winter falls as snow over 1.000 m altitude, and remains stored in snowpack until melting season, when it returns hydrological cycle is partly used for irrigation power generation. Snow cover estimation then one main indicators necessary to evaluate water budget plan management, predict possible drought conditions, drive operational flood prediction.  The use Earth Observation (EO) Cover Area (SCA) has been improved last decade thanks...
