River discharge estimation from satellite
River discharge is defined as the amount of water flowing through a river over a specified period of time. Its estimate is crucial for all the operations of hydraulic structures design, the territorial planning and the flood risk assessment and management. River discharge at a specific river cross-section is not a direct measurement, but it is calculated by measuring other hydraulic quantities such as the flow velocity and the water depth, i.e. ...
Detecting rainfall from the bottom up
SM2RAIN is an innovative system for the estimation of the rainfall, based on measurements of the soil water content. SM2RAIN considers the soil as a natural rain gauge, and by measuring temporal variations of the soil water content, it estimates the rainfall falling on the soil, adopting a “bottom up” approach. Technically, SM2RAIN relies on the inversion of the soil water balance equation that computes the repartition of rainfall in ...
Rainfall estimate from space
We have developed a new satellite rainfall product in near real-time. The product, called H64, is based on the integration of rainfall estimates obtained through two satellite sources. The developed algorithm combines estimates obtained by applying the SM2RAIN algorithm to satellite soil moisture data and those provided by a state-of-the-art product already operating on the full-disk area of the Meteosat satellites (60° West - 60° East, 60° ...
Monitoraggio fluviale da rilevamento satellitare
Although representing less than 1% of the total amount of water on Earth, the freshwater is essential for terrestrial life and human needs. Despite the existing in-situ gauging networks represent a tool for quantifying the instantaneous water volume in many river channels, we have surprisingly poor knowledge of the spatial and temporal dynamics of surface river discharge. Developing new procedures for river discharge estimation based on ...

STSE Water Cycle Multi-mission Observation Strategy for the Mediterranean
Monitoring the water cycle from satellite observations is one of the major goals of the EO community and closing the water budget has been a long-standing objective of international programs. After years of hard work, calibrating satellite data, improving inversion techniques, and facilitating the coherency of retrievals, it is admitted that the water cycle budget can now be ...
SMOS+RAINFALL
Quantitative information about precipitation is one vital input to meteorologists, hydrologic scientists, water resources managers, and environmental legislators. Yet, accurate measurement of precipitation over the relevant space and time scales remains a challenge. Soil moisture can be seen as the trace of the precipitation and, consequently, can be useful for providing a way to estimate rainfall accumulation or at least a new constrain to ...
H-SAF AS: Integration of PR-OBS-5 and SM-OBS-1 products through SM2RAIN algorithm for improving rainfall estimate
State-of-the-art satellite rainfall products are often the only way for measuring rainfall in remote areas of the world. However, these products may fail in properly reproducing the amount of precipitation reaching the ground, which is needed for hydrological applications. The integration of satellite soil moisture products is expected to significantly improve rainfall ...
37 YEARS OF SOIL MOISUTRE DERIVED RAINFALL: application of SM2RAIN to the CCI soil moisture product, algorithm improvement and product validation
Recently, IRPI-CNR has developed an innovative approach for estimating rainfall from satellite soil moisture data, named SM2RAIN. The ESA funded project “Climate Change Initiative - Soil Moisture“ (CCI-SM) offers a valuable opportunity for testing SM2RAIN algorithm to a continuous, homogenous, long-term (>30 years) soil moisture time series. Indeed, SM2RAIN has the chance to be tested not only for rainfall estimation but also as a ...

Hydrological-hydraulic validation of satellite data
The service aims to assess the potential of different satellite products (from active and passive micro-waves, optical, SAR, spectroradiometers, radiometers sensors) in retrieving the main hydrological-hydraulic variables such as rainfall, soil moisture, water level, flow velocity and discharge. This is pursued through a comprehensive validation analysis by using in-situ observed or modelled data for several sited located ...

RelationsHips between meteo-climAtic paraMeters and ground surface deforMation time sEries in mountain enviRonments
There is a systematic lack of information on the effects of the climate and environmental changes on the frequency and the intensity of landslides and their triggering phenomena (Huggel et al., 2012). The problem is particular severe in mountain area, where natural and human-driven climatic and environmental changes may alter significantly the frequency and the intensity of the slope processes, with largely unknown short and long-term effects ...

Analysis and monitoring of Planpincieux Glacier, Monte Bianco massif (AO)
The Planpincieux Glacier is one of the glaciers that characterize the Italian side of the massif of the Grandes Jorasses. It is considered a temperate glacier and its front is currently located near a morphological step that determines a strong propensity to the activation of frequent ice falls in particular during the summer. These phenomena are typical of this glacier, but its particular asset may cause, as already occurred in the past, to ...

Sinkholes in the Marina di Lesina area
Sinkholes are in Apulia among the main geohazards, and are at the origin of severe interactions with the anthropogenic environment, and heavy losses to society. Since several years the territory of Marina di Lesina is diffusely affected by development of sinkholes (that have caused an emergency state to be declared), mostly concentrated near the Acquarotta Channel, linking the Lesina Lake to the Adriatic ...
DInSAR techniques for the assessment of sinkhole hazard
Sinkholes occur as sudden collapses of the ground, related to natural cavities produced by karst processes in soluble rocks, or to man-made cavities deriving from different types of human activities in different historical ages. Sinkholes are widespread all over the world, and the related hazard is extremely high, with very severe damage to built-up areas and human infrastructures, and heavy losses to the ...
Investigation of postglacial fault zones using DInSAR
Fennoscandia bears witness of the Pleistocene glaciation in the form of a series of large geological faults. Pärvie which is the longest runs for 150 km. No information is available on its state of activity and no surface deformations data have ever been collected. The length of the fault and its location, make the traditional monitoring techniques unfeasible and ...
