Detecting rainfall from the bottom up

sm2rain-evidenza-1 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 ...

Radar remote sensing techniques for the detection and measurements of ground surface deformations

DInSAR-in_evidenza- Space-borne radar interferometry or DInSAR (Differential Interferometric Synthetic Aperture Radar) is one of the latest techniques used for the detection and measurement of ground surface deformations caused by natural and / or man-made events. The DInSAR technique has been successfully used in the measurement of seismic deformations and of the effects of subsidence, unstable slopes and inflation of magma in volcanoes. The growth of space ...

What is the origin of the large Isidis Planitia, on Mars?

(b) Shaded map of the free-air anomaly data obtained from the Mars Gravity Model. Black dashed lines indicate location of the profiles used for admittance modeling. (c) Topography and (d) free-air gravity as observed across the central profile. The characterization of an impact crater requires an understanding of the impact phenomena, considering the properties of the materials involved in the impact. The size and energy of the projectile control the width and depth of the crater. Related to impact craters is the formation of mass concentrations, or mascons, which produce intense positive gravity anomalies. One of the largest mascons is in the Isidis Planitia, Mars.Using the ...

Threedimensional Displacement Analysis

prodotti-servizi-3da-evidenza The 3DA software is a new procedure that allows retrieving in near-real-time 3D surface deformation models starting from data acquired via robotized total stations or others system that acquire the surface displacements. The measurements are first pre-processed and then implemented on 3D maps that include vector arrows representative of the intensities and of the real directions of motion in a given system of coordinates. The 3D surface ...

STSE Water Cycle Multi-mission Observation Strategy for the Mediterranean

ESA_WACMOS_MED_IMMEV 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

ESA_SMOS_RAINFALL_IMMEV 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

HSAF_AS_SM2RAIN_IMMEV 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

ESA_CCI_VS_SM2RAIN_IMMEV 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 ...

Use of SMAP soil moisture products for operational flood forecasting: data assimilation and antecedent wetness conditions assessment
