SaTellite based Runoff Evaluation And Mapping

project-STREAM-evidenza L'acqua è al centro dello sviluppo economico e sociale; è fondamentale per la salute, coltivare il cibo, gestire l'ambiente e creare posti di lavoro. Poiché oltre la metà dell'approvvigionamento mondiale di acqua potabile viene estratta dai fiumi, direttamente o da serbatoi, è di primaria importanza comprendere la variabilità dell'acqua immagazzinata sopra e sotto le masse terrestri, cioè il deflusso totale. Le osservazioni in situ o i ...

Studio e monitoraggio dei processi idrologici

Scheme of the HYDROMON project. L'IRPI è da molti anni impegnato nel monitoraggio di variabili idrologiche (umidità del suolo, pioggia, portata e velocità dei corsi d'acqua) che è risultato fondamentale per la rappresentazione del processo di formazione del deflusso e quindi per lo studio delle piene e delle ...

Hydrological monitoring and prediction of shallow landslides through remote sensing observations

project-LANDHYDRO-evidenza Rainfall-induced shallow landslides and floods are the most common and dangerous natural hazards, mainly due to their high temporal frequency, which causes fatalities and high economic damage worldwide. Climate changes will exacerbate this critical framework since an increase in extreme weather events is ...

A new independent GLOBAL rainfall product from ASCAT soil moisture observations through SM2RAIN

project-EUMETSAT_GLOBAL_SM2RAIN-evidenza Accurate rainfall estimates are of paramount importance as rainfall plays a key-role in many fields as, to cite a few, natural hazard assessment (floods and landslides), drought management, weather forecasting, agriculture and diseases prevention. State-of-the-art rainfall products obtained by satellites are often the only way for measuring rainfall in remote areas of the ...

Stima della pioggia dal basso

sm2rain-evidenza-1 SM2RAIN è un innovativo sistema di stima della pioggia che si basa sul contenuto d’acqua nel suolo. SM2RAIN considera il suolo come un grande pluviometro naturale e, misurando le variazioni della quantità di acqua nel suolo, stima la pioggia caduta (approccio “bottom-up”). In termini tecnici, SM2RAIN fa riferimento all’inversione dell’equazione di bilancio idrologico del suolo che calcola la ripartizione delle precipitazioni in ...

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

SMAP_EA_IMMEV The project aims at using Soil Moisture Active and Passive (SMAP) soil moisture (SM) products at different spatial resolution (3, 9, and 36 km) for hydrological applications in Europe (mainly in ...
