Many severe meteorological events occurred in Europe during the last decade and caused casualties and damages to the historical heritage and
natural environment. Protection of civilians and safeguard of the territory are the kay mandates of a civil Protection (CP) agency. This is
achieved through activities that mitigate hydro-meteorological risks, such as flooding and droughts. European CP agencies, supported by
meteorological and hydrological institutes, aim to assess risk scenarios, to monitor and supervise events and risk levels, providing early warning
to National and local authorities.
Near real time accurate estimations of hydrological variables such as precipitation and soil moisture are invaluable to the CP agencies, enable
them to issue early warnings and plan for disaster relief at the local level.
Besides measurements of key hydrological variables by ground-based instruments, often affected by a limited spatial coverage, advanced
satellite-based precipitation and soil moisture products developed within different international programs as H SAF, are available and accessible
to users in near-real time.
In this study, recent severe meteorological events are selected in order to understand how the main satellite product characteristics, i.e.
accuracy, spatial pattern and resolution, update frequency and latency, impact the efficiency of a hydro-meteorological early warning system at a
local level in an operational framework.
