Data formats and standards for opportunistic rainfall sensors [version 2; peer review: 2 approved]

open access: yesOpen Research Europe
Opportunistic 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 ...

Building photonic links for microwave quantum processors

open access: yesNanophotonics
Optical photons play unique role in transmitting information over long distances. Photonic links by the optical fiber networks compose the backbone of today’s global internet. Such fiber optics can also provide the most cost-effective quantum channels to

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.

Phase-Stabilized Delivery for Multiple Local Oscillator Signals via Optical Fiber

open access: yesIEEE Photonics Journal, 2014
In this paper, we propose and demonstrate a multiple local oscillator (LO) signal phase stabilization technique for long-distance fiber delivery. One of the LO signals, which acts as a reference single, is round-trip transferred between the central ...

Regional Attenuation Correction of Weather Radar Using a Distributed Microwave-Links Network

open access: yesAdvances in Meteorology, 2017
The complex temporal-spatial variation of raindrop size distribution will affect the precision of precipitation quantitative estimates (QPE) produced from radar data, making it difficult to correct echo attenuation.

Time-for-space microwave system architecture for multifunctional radar

open access: yesAIP Advances
Traditional RF front-end link typically arranges microwave devices with single functions sequentially in space dimension to process microwave signals, which becomes one of the bottlenecks hindering the softwarization of microwave systems and is ...
