    Data assimilation of radar reflectivity volumes in a LETKF scheme by T. Gastaldo, T. Gastaldo, V. Poli, C. Marsigli, C. Marsigli, P. P. Alberoni, T. Paccagnella

    Published 2018-11-01
    “…<p>Quantitative precipitation forecast (QPF) is still a challenge for numerical weather prediction (NWP), despite the continuous improvement of models and data assimilation systems. In this regard, the assimilation of radar reflectivity volumes should be beneficial, since the accuracy of analysis is the element that most affects short-term QPFs. …”
