Rainfall Nowcasting Using Commercial Microwave Links [PDF]
Geophysical Research Letters, 2020 AbstractAccurate and timely precipitation forecasts are crucial for early warning. Rainfall nowcasting, the process of statistically extrapolating recent rainfall observations, is increasingly used for short‐term forecasting. Nowcasts are generally constructed with high‐resolution radar observations.

Precipitation Classification Using Measurements From Commercial Microwave Links
IEEE Transactions on Geoscience and Remote Sensing, 2014Commercial wireless microwave links have been recently proven to be an effective tool for precipitation monitoring, mainly for accurate rainfall estimation and high-resolution rainfall mapping. This paper focuses on the challenge of precipitation classification from the measurements of received signal level (RSL) in several commercial wireless ...

Recurrent Neural Network for Rain Estimation Using Commercial Microwave Links
IEEE Transactions on Geoscience and Remote Sensing, 2021The use of recurrent neural networks ( $RNN\text{s}$ ) to utilize measurements from commercial microwave links ( $CML\text{s}$ ) has recently gained attention. Whereas previous studies focused on the performance of methods for wet–dry classification, here we propose an RNN algorithm for estimating the rain-rate.

Commercial microwave links for urban drainage modelling: The effect of link characteristics and their position on runoff simulations [PDF]
Journal of Environmental Management, 2019 Commercial microwave links (CMLs), radio connections widely used in telecommunication networks, can provide path-integrated quantitative precipitation estimates (QPEs) which could complement traditional precipitation observations. This paper assesses the ability of individual CMLs to provide relevant QPEs for urban rainfall-runoff simulations and ...

Uncertainties in Short Commercial Microwave Links Fading Due to Rain
ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020A Power-Law relation between attenuation and rain rate has proven to be a useful tool in wireless network design at microwave and mmWave frequencies. In the last decade this relation has also been used for estimating rain from signal level measurements in Commercial Microwave Links (CMLs).

Precipitation observation using commercial microwave communication links
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012Rain rate observation over complex terrain is still afflicted with large uncertainties introduced by system inherent drawbacks of radar and gauge measurements. We use a new method for near surface rain rate estimation exploiting attenuation data from commercial microwave backhaul links.

Quantification and Modeling of Wet-Antenna Attenuation for Commercial Microwave Links
IEEE Geoscience and Remote Sensing Letters, 2013Data from a new experimental setup deployed in Dubendorf (Switzerland) are used to quantify and model the magnitude and dynamics of the wet-antenna attenuation (WAA) affecting a 1.85-km commercial microwave link at 38 GHz. The results show that the WAA exhibits the following properties: 1) It is bounded by a maximum value of about 2.3 dB; 2) it ...
