The need for more efficient use and effective management of water resources is a critical global issue facing the 21st century. To address hydrologic hazards and manage water resources systems, scientists and engineers have become more reliant on the use of predictive models and stochastic methods. The hydrometeorological information needed may range from hourly forecasts (i.e., in the case of flash floods) to seasonal to inter-annual (i.e., in the case of reservoirs and other water resources system operations), and to decadal to century (i.e., in the case of long-range water supply planning and structural designs). Utility of various numerical models for practical applications will depend on the success of testing and validation against historical observations. The availability of in-situ observational data of sufficient spatial and temporal resolutions, especially at the global scale, poses a major challenge. An alternative to ground-based observations is the use of Satellite remote sensing to estimate key hydrometeorological variables such as precipitation. This presentation introduces new data products based on the PERSIANN system, developed at CHRS at UC Irvine. It is available near real-time high-resolution (4km, 30 min.) dataset iRain and the 34 years+ (Daily, 25 km) precipitation Climate Data Record known as PERSIANN-CDR, which is becoming a widely used dataset, will be presented.
