Real time data acquisition of commercial microwave link networks for hydrometeorological applications [PDF]
Atmospheric Measurement Techniques, 2015 Abstract. The usage of data from commercial microwave link (CML) networks for scientific purposes is becoming increasingly popular, in particular for rain rate estimation. However, data acquisition and availability is still a crucial problem and limits research possibilities.

Data formats and standards for opportunistic rainfall sensors [version 2; peer review: 2 approved]
Open Research EuropeOpportunistic sensors are increasingly used for rainfall measurement. However, their raw data are collected by a variety of systems that are often not primarily intended for rainfall monitoring, resulting in a plethora of different data formats and a ...

Precipitation observation using microwave backhaul links in the alpine and pre-alpine region of Southern Germany [PDF]
Hydrology and Earth System Sciences, 2012 Measuring rain rates over complex terrain is afflicted with large uncertainties, because rain gauges are influenced by orography and weather radars are mostly not able to look into mountain valleys. We apply a new method to estimate near surface rain

Commercial microwave links instead of rain gauges: fiction or reality?
Water Science and Technology, 2014 Commercial microwave links (MWLs) were suggested about a decade ago as a new source for quantitative precipitation estimates (QPEs). Meanwhile, the theory is well understood and rainfall monitoring with MWLs is on its way to being a mature technology, with several well-documented case studies, which investigate QPEs from multiple MWLs on the mesoscale.

Combining commercial microwave links and weather radar for classification of dry snow and rainfall [PDF]
Atmospheric Measurement TechniquesDifferentiating between snow and rainfall is crucial for hydrological modeling and understanding. Commercial microwave links (CMLs) can provide rainfall estimates for liquid precipitation but show minimal signal attenuation during dry snow events ...

CLEAR: a new discrete multiplicative random cascade model for disaggregating path-integrated rainfall estimates from commercial microwave links [PDF]
Atmospheric Measurement TechniquesA novel disaggregation algorithm for commercial microwave links (CMLs), named CLEAR (CML Segments with Equal Amounts of Rain), is proposed. CLEAR utilizes a multiplicative random cascade generator to control the splitting of link segments, with the ...
