An investigation of errors in distributed models’ stream discharge prediction due to channel routing

June 27, 2019 in /by

The authors analyzed the results of the Land Surface Model and the Routing Application for Parallel Computation of Discharge. The authors took the results – which showed that enhancements were still possible for the programs – and investigated the source of the errors. Their research resulted in an improvement in model performance.   ElSadaani, M., W.F. […]

River network based characterization of errors in remotely sensed rainfall products in hydrological applications

June 27, 2019 in /by

The authors propose a hydrologic evaluation framework for gridded rainfall products. The framework will aid in the compilation of rainfall data and lower the chance for errors with satellite rainfall products in hydrologic applications.   ElSadaani, M., W.F. Krajewski, and D.L. Zimmerman, River network based characterization of errors in remotely sensed rainfall products in hydrological applications, Remote […]

Spatial variability and temporal persistence of event runoff coefficients over agricultural land

June 27, 2019 in /by

The analysis of unique rainfall-runoff data can offer more in-depth knowledge than the current internal spatial variability of small-scale runoff yield. Through the use of 12 unique hills, the authors intend to reduce the error of runoff data.   Chen, B., W.F. Krajewski, M. Helmers, and Z. Zhang, Spatial variability and temporal persistence of event […]

Inter-comparison of reflectivity measurements between GPM DPR and NEXRAD Radars

June 27, 2019 in /by

Reflectivity measurements are one example of a measurement that can be taken from GPM, DPR, and NEXRAD radars. This study demonstrates the potential use of the NASA’s Global Precipitation Measurement (GPM) Dual-frequency Precipitation Radar (DPR) to examine ground radar (GR) miscalibration and other uncertainty sources (e.g., partial beam blockage).   Keem, M., B.-C. Seo, W.F. Krajewski, […]
