Abstract Rainfall monitoring based on commercial terrestrial microwave links is tested for the first time in Burkina Faso, Sahelian West Africa. In collaboration with one national cellular phone operator, Telecel attenuation a 29 km long link operating at 7 GHz was monitored 1 s rate monsoon season 2012. The series of transformed into rain rates and compared gauge data. method successful quantifying rainfall: 95% rainy days are detected. correlation daily 0.8, bias 6%. 5 min step within each...

In addition to sensors such as rain gauges, ground-based radars and satellites, data from Commercial Microwave Link (CML) can provide important information on rainfall. A CML acquisition system (DAQ) has been in place since 2017 a pilot project with eight links the city of Ouagadougou gradually expanded. During 2020 monsoon season, DAQ temporal resolution one minute progressively increased CMLs over 1000 CMLs. Here we present results analysis rainfall derived Ouagadougou. Validation is...
Water resource access in the Nouhao sub-basin, assessed based on availability of drinking water mobilization facilities, for uses and quality water, revealed that 2017 basin was covered by 1249 modern point, main sources. On average, sub-basin shows a ratio 271 users per point. Communal level some disparity with Bittou recording highest number people i.e., around 537. can be captured entire meets only 42% total needs from three mains uses: irrigation, domestic consumption livestock. The...
Colorless, incessant radon gas is notably the second most important cause of lung cancer after smoking in smokers and first non-smokers. Having little effect atmosphere, accumulates confined spaces. Therefore, determination concentrations inside residential buildings very to improve health inhabitants. The objective this research measure concentration indoor air areas city Kaya assess absorbed dose, effective dose relative risk cancer. In study, CORENTIUM AIR THINGS digital detector used...
Accurately measuring meteorological visibility is an important factor in road, sea, rail, and air transportation safety, especially under visibility-reducing weather events. This paper deals with the application of Machine Learning methods to estimate dusty conditions, from power levels commercial microwave links data including temperature, dew point, wind speed, direction, atmospheric pressure. Three well-known are investigated: Decision Trees, Random Forest, Support Vector Machines. The...
Electromagnetic waves emitted between antennas interact with the atmosphere, undergoing absorption, scattering, and emission processes. Previous studies have shown that relationship specific attenuation (K) due to rain of these microwaves precipitation rate (R) can be modeled by an empirical power law. The coefficients "a" "b" this relationship, linking microwave signal rate, vary depending on frequency, temperature, raindrop size distribution, other parameters. Thus, it is crucial obtain...
Since the 1990s, mobile telecommunication networks have gradually become denser around world. Nowadays, large parts of their backhaul network consist commercial microwave links (CMLs). CML signals are attenuated by rainfall, exploitation records this attenuation is an innovative and inexpensive solution for precipitation monitoring purposes. Performance data from operators’ crucial implementation technology. Therefore, a real-time system collecting storing power levels phone operator...
With the exponential increasing of mobile phone users, CML network in West Africa is growing, and thus providing a high potential for CML-derived precipitation measurements. In this work we use performances data CMLs to determine rainfall quantities rainy event which marked memory inhabitants capital Ouagadougou on September 1<sup>st</sup>, 2009. study attenuation microwave link establish rain rate. The working frequency 13 GHz, path length 7.5 Km vertical polarization. time series are...
Several factors can attenuate radio signal between transmitting and receiving antenna. One cite: vegetation, atmospheric gases, fog, water vapor, transmission instruments, rain, temperature, etc... The sources of attenuation differ according to the climate relief each continent or even country. In this work we aim show that there is link microwave weather visibility in presence dust. Weather a very important factor for safety road, sea, rail air transportation. dust, strongly reduced also...
We have more innovation on Ethernet wireless links nowadays. The introduction of the E-band and V-Band provide spectral capacity to build microwave with high throughput. That is done MPLS in a technology. In this paper we describe evolution, application best opportunities use frequency for 2G/3G/4G/5G mobile networks, fiber backup links, enterprise networks VIP lines. present air link capacity, layer 2 throughput without IFG preambule suppression. results by simulations prove possibility one...
Forecast analysis of hydro-climatics data Nouhao Sub-Basin shows how useful local rain gauges collected by population during 4 to 7 years in three (03) villages on the experimental site for planning and forecasting. The first results show that i) breakdown series determines seasonality occurrence "casual" rains; ii) auto-correlation detection test showed casual rains are not self-correlated validates model; iii) dry/rainy season cycle is from mid-October April mid-April this site, iv)...
Sahelian countries are confronted with a lack of reliable data on water and climate allowing them to understand the effects variability. To address this situation, support Water Aid, we have collected rainfall groundwater level in wells from 2012 2018 help local populations. Their contribution made it possible cover wider geographical area obtain necessary analyze variability small large scale sub-basin Nouhao. The well correlated those rain gauges national meteorological agency region Fada...
In this study, wepropose a new method for detecting wet periods by using telecommunicationsCommercial Microwave Links (CML). The purpose of the study is to automaticallyfind rain time slots. attenuation microwave signal, propagatingbetween transmitting antenna and receiving one, due variations ofthe climatic conditions over link, non-stationary signal. When rainevent occurs CML, signal level increases proportionallyto amount. This decreases again at end rain. Theseabrupt are exploited here...
