The Attenuation of Swell Waves by Rain [PDF]
Geophysical Research Letters, 2017 AbstractWithin the progressive improvement in wave modeling we focus on the attenuation of swell waves by rain. Till now ignored, the process is shown to be relevant, especially for the correct estimate of swell. Following the practical impossibility of devoted field experiments, we exploit the global model results over a period of more than four years

Rain‐rate estimation algorithm using signal attenuation of Ka‐band cloud radar
Meteorological Applications, 2020 A millimetre‐wave cloud radar has limitations for observing heavy rainfall because the short wavelength leads to strong attenuation from raindrops. However, recent studies have attempted to estimate the rain rate using attenuation, which becomes greater ...
