locations of the rain gauges of the FCDMC network, with colors indicating the corresponding record length. Urbanized areas are also shown. (d) Distribution of the intergauge distance. We use records of the Automated Local Evaluation in Real Time (ALERT) rain gauge network of the Flood Control District of the Maricopa County (FCDMC), installed to monitor in real time regional and localized storms, and support flood and flash-flood forecasting. The gauges have been gradually deployed since the beginning

operational limitations of the standard KF, namely, (i) the nonlinearity of many dynamical systems and (ii) the high computational effort required for the storage and forward integration of the forecast error covariance in large systems. In the EnKF, the covariance is estimated from the generation of an ensemble (statistical sample) of state replications. The EnKF has proved to be a robust estimator even in presence of deviation from Gaussianity assumption ( Katzfuss et al. 2016 ). Many successful

the daily and subdaily scales are more important from the standpoint of operational watershed hydrology and water resources management for applications such as flood forecasting. Furthermore, since PDIR-Now is an IR-based precipitation dataset, it is intended to be particularly advantageous in providing timely and adequate precipitation estimates when other datasets based on PMW and multisensor fusion are not available. With these considerations in mind, analysis of PDIR-Now at the daily and

current operational algorithm is allowed to use radar-observed convective fraction information (bright blue) as an additional ancillary parameter (see section 4a ). As expected, a better match to the reference suggests that the information on convective fraction might be a key to mitigating PMW biases seen in Fig. 1 . However, radar observations of precipitation from space are sparse, typically limited to research missions (e.g., TRMM and GPM) and intended to serve as a reference rather than a

model to generate landslide hazard forecasts. We anticipate that other environmental prediction models such as the Global Flood Monitoring System ( Wu et al. 2012 ) and the Global Land Data Assimilation System (GLDAS; Fang et al. 2009 ) could likely benefit from deeper consideration of SMPP uncertainty and error—both systematic and random. In this study, we found it necessary to modify (albeit modestly) the operational LHASA framework to accommodate IMERG uncertainty estimates, as opposed to

resolutions are critical for near-real-time applications such as rapid monitoring and forecasting of high-impact societal events like flash floods, debris flows, and shallow landslides. Such resolution can be obtained primarily from satellite sensors on board geostationary Earth orbit (GEO) platforms. NOAA’s Advanced Baseline Imager (ABI) sensor on board the latest generation of Geostationary Operational Environmental Satellites (GOES-R Series) provides 3 times more spectral channels, 4 times the

The TRMM ( Kummerow et al. 2000 ) and GPM ( Hou et al. 2014 ; Skofronick-Jackson et al. 2017 ) satellite missions in particular provided the data and the research framework allowing the successful development of research and operational retrieval algorithms. Today, the GPM Microwave Imager (GMI) is integrated in an international constellation
