dc.description
Climate change is profoundly affecting the global water, energy and carbon cycles and increasing the likelihood and severity of extreme events. Better decision support systems are essential to accurately predict and monitor environmental disasters and to optimally manage water and environmental resources. An effective combination of state-of-the-art remote sensing products, in-situ observations and advanced hydrological modelling is needed to improve our knowledge of the water cycle and to enhance early warning and monitoring systems for floods and droughts in Africa. In the EUMETSAT Satellite Application Facility on Support to Operational Hydrology and Water Management (H SAF) project (https://hsaf.meteoam.it/), operational satellite products for estimating precipitation and soil moisture are available and distributed in near real time for the entire African continent. Two main precipitation products are provided: (1) the precipitation rate product (called H60), generated by combining geostationary infrared imagery and passive microwave radiometer observations (15 min, 4.8 km), delivered with a very short latency (15 min) suitable for near real-time applications, e.g. flash floods, landslides; and (2) the daily accumulated rainfall product (H64), obtained by merging soil moisture derived rainfall with passive microwave rainfall estimates from radiometer (1 day, 25 km), delivered with 1 day latency and suitable for long-term applications such as rainfall-runoff modelling and climate monitoring. For soil moisture, two main products are provided: (1) the surface soil moisture product (H122) obtained from the Advanced SCATterometer (ASCAT) (daily, 6.25 km); and (2) the root zone soil moisture product (H26) obtained by assimilation of the surface product into the ECMWF modelling system (daily, 10 km), available for a layer depth of 0 to 289 cm. Long-term data record (>15 years) are also available for the different products. The presentation will give a brief overview of the precipitation and soil moisture products and in particular their use for operational applications in Africa through case studies (e.g. Nigeria flood in October 2022 and Libya flood in September 2023) and long-term implementation for river discharge estimation in more than 400 basins in Africa.
