Intercomparison of attenuation correction algorithms for single-polarized X-band radars
Lengfeld, Katharina; Berenguer Ferrer, Marc; Sempere Torres, Daniel (2018-03)
Article
Accés obertAttenuation due to liquid water is one of the largest uncertainties in radar observations. The effects of attenuation are generally inversely proportional to the wavelength, i.e. observations from X-band radars are more ... -

Park, Shinju; Berenguer Ferrer, Marc; Sempere Torres, Daniel (Elsevier, 2019-06)
Article
Accés obertMonitoring continental precipitation over Europe with high resolution (2 km, 15 min) has been possible since the operational production of the OPERA composites from the European weather radar networks. The OPERA data are ... -
