Can GNSS reflectometry detect precipitation over oceans? [PDF]
Geophysical Research Letters, 2020 For the first time, a rain signature in Global Navigation Satellite System Reflectometry (GNSS‐R) observations is demonstrated. Based on the argument that the forward quasi‐specular scattering relies upon surface gravity waves with lengths larger than ...

Estimating Wave Direction Using Terrestrial GNSS Reflectometry [PDF]
Remote Sensing, 2019 The signal-to-noise ratio (SNR) data are part of the global navigation satellite systems (GNSS) observables. In a marine environment, the oscillation of the SNR data can be used to derive reflector heights. Since the attenuation of the SNR oscillation is
