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 […]
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 […]
NEXRAD collects and stores rainfall data in a cloud, allowing the IFC to develop a program to retrieve the data and create a map. The map has the benefit of allowing researchers to choose a specific area of study. Seo, B.-C., M. Keem, R. Hammond, I. Demir, and W.F. Krajewski, A pilot infrastructure for searching rainfall […]
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, […]
A stochastic model was created to create high resolution surface soil moisture information. Jadidoleslam, N., R. Mantilla,W.F. Krajewski and M. Cosh, Data-driven stochastic model for basin and sub-grid variability of SMAP satellite soil moisture, Journal of Hydrology, 2019 (in press).
The results point to increasing trends in heavy rainfall over the northern part of the study domain. Examination of the surface temperature record suggests that these increasing trends occur over the area with the largest increasing trends in temperature and, consequently, with an increase in atmospheric water vapor. Villarini, G., J.A. Smith, M.L. Baeck, R. […]
The focus of this study is to evaluate: (1) “mixtures” of flood peak distributions, (2) upper tail and scaling properties of the flood peak distributions, and (3) presence of temporal nonstationarities in the flood peak records. Villarini, G., J.A. Smith, M.L. Baeck, and W.F. Krajewski. “Examining Regional Flood Frequency in the U.S. Midwest,” Journal of the American […]
