    Article
    Open Access
    During the second week of September 2013, a seasonally uncharacteristic weather pattern stalled over the Rocky Mountain Front Range region of northern Colorado bringing with it copious amounts of moisture from the Gulf of ...
  • A water availability prediction system for water management 

    Llort Pavon, Xavier; Rodríguez, Álvaro; Sancho, David; Sánchez-Diezma Guijarro, Rafael; Cangròs Alonso, Arnau; Muñoz Morillo, Esteban; Berenguer Ferrer, Marc; Sempere Torres, Daniel (2015)
    Conference report

    In this work we present a Water Availability Prediction System [WAPS] developed and implemented within two EU-FP7 projects: UrbanWater and WatERP. The aim of the WAPS is to provide information for management purposes, and ...
  • Debris-flow forecasting at regional scale by combining susceptibility mapping and radar rainfall 

    Berenguer Ferrer, Marc; Sempere Torres, Daniel; Hurlimann Ziegler, Marcel (2015-03-13)
    Article
    Open Access
    This work presents a technique for debris-flow (DF) forecasting able to be used in the framework of DF early warning systems at regional scale. The developed system is applied at subbasin scale and is based on the concepts ...
  • Adaptive reconstruction of radar reflectivity in clutter-contaminated areas by accounting for the space-time variability 

    Park, Shinju; Berenguer Ferrer, Marc (Elsevier, 2014-11-12)
    Article
    Open Access
    Identification and elimination of clutter is necessary for ensuring data quality in radar Quantitative Precipitation Estimates (QPE). For uncorrected scanning reflectivity after signal processing, the removed areas have ...
  • Skill in nowcasting high-impact heavy precipitation events 

    Bech, Joan; Berenguer Ferrer, Marc (2014)
    Conference lecture
    Open Access
    The objective of this study is to assess the skill of a precipitation nowcasting (very short range forecasting) system, with particular emphasis on hig-impact Heavy Precipitation Events (HPE). A threshold amount of 20 mm ...
  • The use of NWP forecasts to improve an ensemble nowcasting technique 

    Buil Martínez, Alejandro; Berenguer Ferrer, Marc; Sempere Torres, Daniel (2014)
    Conference lecture
    Open Access
    Quantitative Precipitation Nowcasting (QPN) is one of the main applications of radar observations. On one hand, one of the most used nowcasting algorithms is Lagrangian extrapolation. It shows skill in specifying the timing ...
  • An inverse method to retrieve 3D radar reflectivity composites 

    Roca Sancho, Jordi; Berenguer Ferrer, Marc; Sempere Torres, Daniel (Elsevier, 2014-11)
    Article
    Open Access
    Dense radar networks offer the possibility of getting better Quantitative Precipitation Estimates (QPE) than those obtained with individual radars, as they allow increasing the coverage and improving quality of rainfall ...
  • Debris flow warning through radar nowcasting and critical rainfall thresholds: a case study in the Glarus catchment (Switzerland) 

    Mitidieri, Francesco; Papa, Maria Nicolina; Ciervo, Fabio; Berenguer Ferrer, Marc; Sempere Torres, Daniel; de Medina Iglesias, Vicente César; Bateman Pinzón, Allen (Springer, 2015)
    Part of book or chapter of book
