Global SM2RAIN

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

Funded by EUMETSAT 

Period: 01/11/2017 – 31/12/2020

Partners: The consortium is leaded by CNR-IRPI with the collaboration of Vienna University of Technology, Department of Geodesy and Geoinformation

Description: 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 world.
The main objectives of GLOBAL SM2RAIN project are to generate a new global scale and high resolution satellite rainfall product obtained by ASCAT and to prepare for a potential operational implementation in the EUMETSAT H SAF framework, complementing the currently planned H SAF SM2RAIN activities but on a global scale. The expectation is that this product will improve the accuracy over land with respect to state-of-the-art satellite products and the performance of operational tools for flood, drought and landslide hazard assessment and mitigation.
A global daily rainfall dataset has been obtained in the GLOBAL SM2RAIN project:

Time coverage: 2007-2019. Spatial\temporal resolution: 12.5 km\1-day.
