Estimating near ground precipitation from permanent recordings of received signal fading in commercial microwave links (CMLs) is a promising and emerging technique in weather observation. It is particularly valuable for regions with sparse or even nonexistent weather radar and rain gauge coverage to support hydrological modeling and to enhance regional severe weather warning.

One of the main attractions in in using CMLs for hydrology is in their potential for creating 2-D near-ground rainfall maps. Since 2008, various methods have been presented for 2-D rain retrieval from CMLs and their operation has been demonstrated in different regions around the world. In this talk I will present results of our theoretical study under the IMAP project of the achievable...
Air-moisture maps were generated based on commercial microwave links data over N. Israel and compared with ECMWF ERA-Interim maps. Skill scores were calculated utilizing 39 weather stations. High correlations range, 0.75–0.9, were found between the new links’ humidity fields and the stations. The numbers of best correlated links are found to be higher compared to ECMWF, and in the measure of...
Commercial microwave links (CMLs) from cellular communication networks have been used for rainfall monitoring in the Netherlands since 2003. We provide an overview of our work in the Netherlands with an emphasis on country-wide application using CML data from T-Mobile NL from networks with different sampling strategies. The open-source R package RAINLINK is described, explaining the processing...
This contribution overviews the state-of-the-art of the research dedicated to rainfall monitoring through wireless microwave links in Italy. Early studies on the application of tomography to retrieve 2D rainfall fields from a mesh of terrestrial microwave links date back to the nineties. A pioneering experimental work was carried out in 2001 in the framework of the MANTISSA project. More...
There are more than 300,000 satellite ground terminals across Europe and 2 million worldwide which are being used for providing broadband internet services. To maintain a certain level of quality of service, gateway stations (of satellite operators) continuously monitor links between satellite and ground terminals (enabled by the bidirectional link). Carrier-to-Noise ratio (C/N) parameter...
Abstract
In the last decade, various algorithms have been developed to provide accurate rainfall maps from measurements of rain-induced attenuation on commercial wireless links (CWLs).
These solutions are able to give precise results but they also require dense terrestrial microwave networks, which have non negligible installation and operating costs.
A cheaper alternative for...
