Accumulated Mixed Precipitation Estimation Using Measurements from Multiple Microwave Links

open access: yesAdvances in Meteorology, 2015
Recently, microwave communication networks have been shown to be valuable tools for rainfall monitoring, based on the well-known Power-Law which relates rain-rate to attenuation in microwave frequencies.

Towards Innovative Solutions for Monitoring Precipitation in Poorly Instrumented Regions: Real-Time System for Collecting Power Levels of Microwave Links of Mobile Phone Operators for Rainfall Quantification in Burkina Faso

open access: yesApplied System Innovation, 2022
Since the 1990s, mobile telecommunication networks have gradually become denser around the world. Nowadays, large parts of their backhaul network consist of commercial microwave links (CMLs). Since CML signals are attenuated by rainfall, the exploitation

Potential of commercial microwave link network derived rainfall for river runoff simulations

open access: yesEnvironmental Research Letters, 2017
Commercial microwave link networks allow for the quantification of path integrated precipitation because the attenuation by hydrometeors correlates with rainfall between transmitter and receiver stations.

Humidity Measurements using Commercial Microwave Links

open access: yes, 2011
Atmospheric humidity strongly affects the economy of nature and has a cardinal part in a variety of environmental processes (e.g. Allan et al., 1999). As the most influential of greenhouse gases, it absorbs long-wave terrestrial radiation. Through the water vapour evaporation and recondensation cycle, it plays a central part in the Earth's energy ...

Missing Rainfall Extremes in Commercial Microwave Link Data Due To Complete Loss of Signal

open access: yesEarth and Space Science, 2023
An important aspect of rainfall estimation is to accurately capture extreme events. Commercial microwave links (CMLs) can complement weather radar and rain gauge data by estimating path‐averaged rainfall intensities near ground.

Rain Field Retrieval by Ground-Level Sensors of Various Types

open access: yesFrontiers in Signal Processing, 2022
Rain gauges (RGs) have been utilized as sensors for local rain monitoring dating back to ancient Greece. The use of a network of RGs for 2D rain mapping is based on spatial interpolation that, while presenting good results in limited experimental areas ...

High-Resolution Humidity Observations Based on Commercial Microwave Links (CML) Data—Case of Tel Aviv Metropolitan Area

open access: yesRemote Sensing, 2023
The humidity in the atmosphere plays a crucial role in a wide range of atmospheric processes determined by the water-vapor concentration in the air. The accuracy of weather forecasts is largely dictated by the humidity field measured at low atmospheric ...

Independent Amplitude and Phase Control of Two Orthogonal Linearly Polarised Light and Its Applications

open access: yesIEEE Photonics Journal, 2021
A technique to provide independent control on the amplitude and phase of two orthogonal linearly polarised light is presented. It is based on operating a commercial dual-polarisation dual-drive Mach Zehnder modulator (DPol-DDMZM) in reverse direction ...

A measurement campaign to assess sources of error in microwave link rainfall estimation [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
We present a measurement campaign to address several error sources associated with rainfall estimates from microwave links in cellular communication networks. The core of the experiment is provided by three co-located microwave links installed between
