UNESCO-IHP has collaborated with the Center for Hydrometeorology and Remote Sensing (CHRS)at the University of California, Irvine, on the development of tools to provide near real-time globalsatellite precipitation estimates at high spatial and temporal resolutions, including thePrecipitation Estimation from Remotely Sensed Information using the Artificial Neural Networks-Cloud Classification System (PERSIANN-CCS) [66]. This specific system is used to informemergency planning and manage hydrological risks, such as floods, droughts, and extremeweather events. For example, the Namibia Drought Hydrological Services (NHS) uses it to preparedaily bulletins with up-to-date information on flood and drought conditions for loUNESCO-IHP has collaborated with the Center for Hydrometeorology and Remote Sensing (CHRS)at the University of California, Irvine, on the development of tools to provide near real-time globalsatellite precipitation estimates at high spatial and temporal resolutions, including thePrecipitation Estimation from Remotely Sensed Information using the Artificial Neural Networks-Cloud Classification System (PERSIANN-CCS) [66].
