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° South – 75° North).
The integration between two estimates obtained through such different techniques provides a product characterized by greater accuracy and better performance that will provide a valid input to early warning system for predicting natural risks.
The product has been developed within the HSAF (Satellite Application Facility on Support to Operational Hydrology and Water Management) project, funded by Eumetsat, the European Organization for the Exploitation of Meteorological Satellites and in collaboration with CNR ISAC.
The product is available daily and will soon be released within the HSAF project.
