Discrete entropy theory for optimal redesigning of salinity monitoring network in San Francisco bay
The paper presents an entropy-based method for designing an optimum bay water salinity monitoring network in San Francisco bay (S.F. bay) considering maximum-monitoring-information and minimum-data-lost criteria. Due to cost concerns, it is necessary to design the optimal salinity monitoring network with a minimal number of sampling stations to provide reliable data. The monthly data recorded ...

Monitoring network optimisation for spatial data classification using support vector machines
The paper presents a novel method for monitoring network optimisation, based on a recent machine learning technique known as support vector machine. It is problem-oriented in the sense that it directly answers the question of whether the advised spatial location is important for the classification model. The method can be used to increase the accuracy of classification models by taking a small ...

Information theory applied to evaluate the discharge monitoring network of the Magdalena River
The acquisition of good hydrologic information is an important issue in water management since it is the basis of decisions concerning the allocation of water resources to different users. However, sufficient data are often not available to describe the behaviour of such systems, especially in developing countries, where monitoring networks are inappropriately designed, poorly operated or are ...

Evaluation of detection abilities of monitoring networks using multiple assessment criteria
The problem of evaluation of radiation monitoring network quality is considered. The comparison of possible network configurations is performed on simulated experiments where a twin model is used to simulate observed data. An assimilation procedure based on the particle filter approach is run for each configuration of the network. Specifically, multiple realisations of segmented Gaussian plume ...

Weather forecasting under extreme conditions in Russia - Megafon Russia - Case Study
The National Weather Service in Russia has about 1.800 weather stations which are distributed over the entire area of Russia. That's not enough to cover weather extremes everywhere. So the Russian National Weather Service wants to create a compression ratio of measurement points. In order to achieve the budget targets, our customer decided to buy our all-in-one sensor WS600-UMB. According to ...

Optimal design of groundwater-level monitoring networks
Groundwater monitoring plays a significant role in groundwater management. This study presents an optimization method for designing groundwater-level monitoring networks. The proposed design method was used in the Eshtehard aquifer, in central Iran. Three scenarios were considered to optimize the locations of the observation wells: (1) designing new monitoring networks, (2) redesigning ...

Geostatistically based optimization of a rainfall monitoring network extension: case of the climatically heterogeneous Tunisia
Rainfall data are an essential input for many simulation models. In fact, these latter have a decisive role in the development and application of rational water policies. Since the accuracy of the simulation depends strongly on the available data, the task of optimizing the monitoring network is of great importance. In this paper, an application is presented aiming at the evaluation of a ...

Homogeneous climate regions in Pakistan
In this study, monthly average meteorological data and spatial coordinates are supposed to influence the climate variation. The geographical coordinates are transformed by using the Lambert projection method and are combined with the meteorological data. The complete data is standardised with zero mean and unit variance to remove the effect of different measurement scales. Various clustering ...

Multiple sensor fault detection and isolation of an air quality monitoring network using RBF-NLPCA model
This paper presents a data-driven method based on non-linear principal component analysis to detect and isolate multiple sensor faults. The RBF-NLPCA model is obtained by combining a principal curve algorithm and two three-layer radial basis function (RBF) networks. The reconstruction approach for multiple sensors is proposed in the non-linear case and successfully applied for multiple sensor ...

Pondering a future of severe aerosol pollutions in Nigeria and the need for a monitoring network
Nigeria is usually under the influence of significant natural aerosol loading. The country is the most populous in Africa with an estimated number of over 130,000,000 people and records one of the highest population growth rates in the world. It is the sixth largest oil-producing country in the world and a regional power in West Africa with great potentials for rapid industrialisation and ...

Practical use of the ISCST3 model to select monitoring site locations for air pollution control
We present an objective methodology for selection of the minimum number of sampling sites required to register the highest concentration values of air pollutants emitted from a continuous point source. The methodology is based on the analysis of 1-hour concentration values above a threshold value estimated by atmospheric dispersion models. The number and location of the air monitoring stations ...

Rieger and Vanrolleghem: monEAU: A platform for water quality monitoring networks
Abstract: Continuous monitoring of water quality creates huge amounts of data and therefore requires new concepts to guarantee high data quality and to prevent data graveyards. Monitoring stations commonly used in practice today suffer from insufficient flexibility and a lack of standardization. That is, although a lot of monitoring tasks are comparable and should lead to robust and powerful ...

Crucial elements and technical implementation of intelligent monitoring networks
Growing complexity of water monitoring instrumentation leads to specialized solutions in respect to sensor integration across several measurement device suppliers. Despite efforts of standardization for data interfaces and protocols, problems regarding the combination of several devices to gain the complete picture in terms of water quality remain. This assessment, especially accomplished from ...

Plot-scale assessment of soil freeze/thaw detection and variability with impedance probes: implications for remote sensing validation networks
Several large in-situ soil moisture-monitoring networks currently exist over seasonally frozen regions that may have use for the validation of remote sensing soil freeze/thaw (F/T) products. However, further understanding of how the existing network instrumentation responds to changes in near surface soil F/T is recommended. This case study describes the results of a small plot-scale (7 × 7 ...
