  • Accurate and Reliable Rainfall Measurements using Multiple X-band Compact Radars

    Introduction Recent serious threats to civilian lives due to localized heavy rains, larger typhoons and other meteorological events have been increasing. Many countries consolidate infrastructures that control rivers and sewage. They are creating systems to predict flow amounts and adding these capabilities to their existing weather observation and prediction systems. Each country deploys ...

  • Big data and hydroinformatics

    Big data is popular in the areas of computer science, commerce and bioinformatics, but is in an early stage in hydroinformatics. Big data is originated from the extremely large datasets that cannot be processed in tolerable elapsed time with the traditional data processing methods. Using the analogy from the object-oriented programming, big data should be considered as objects encompassing the ...

  • Assimilation of weather radar and binary ubiquitous sensor measurements for quantitative precipitation estimation

    Assimilation of data from heterogeneous sensors and sensor networks is critical for achieving accurate measurements of environmental processes at the time and space scales necessary to improve forecasting and decision-making. Owing to different measurement accuracies and types of spatial and/or temporal measurement support of the component sensors, it is often unclear how best to combine these ...

  • Evaluating the accuracy of C- and X-band weather radars and their application for stream flow simulation

    This paper investigates the accuracy of rainfall estimates from C- and X-band weather radars and their application for stream flow simulation. Different adjustment procedures are applied to raw radar estimates using gauge readings from a network of 12 raingauges. The stream flow is simulated for the 48.17 km2 Molenbeek/Parkbeek catchment located in the Flemish region of Belgium based on a lumped ...

  • Development of method for X-band weather radar calibration

    Calibration of the X-band LAWR (Local Area Weather Radar) is traditionally based on an assumed linear relation between the LAWR radar output and the rainfall intensity. However, closer inspection of the data reveal that the validity of this linear assumption is doubtful. Previous studies of this type of weather radar have also illustrated that the radar commonly has difficulties in estimating ...

  • Radar-rainfall estimation algorithms of Hydro-NEXRAD

    Hydro-NEXRAD is a prototype software system that provides hydrology and water resource communities with ready access to the vast data archives of the U.S. weather radar network known as NEXRAD (Next Generation Weather Radar). This paper describes radar-rainfall estimation algorithms and their modular components used in the Hydro-NEXRAD system to generate rainfall products to be delivered to ...
