  • Operational short-range analytical air pollution modelling

    Operational models that use solutions of the advection-diffusion equation based on more realistic assumptions than that of homogeneous wind and eddy diffusivity coefficients are presented. In particular, these solutions accept that wind and eddy diffusivity profiles are power functions of the height. Moreover, a practical short-range model evaluating ground-level concentrations from elevated ...

  • Solar/wind power for noise monitoring terminals

    Solar Power Solutions A noise monitoring terminal’s (NMT) low power consumption and its ability to operate fully without power hungry cooling and heating units inside its enclosure mean that it is suitable for power from solar panels. The NMT may be continuously powered by battery which in turn is kept charged via solar energy. This solution is most appropriate in areas where there ...

  • Comparison of two different operational models for complex terrain in neutral flow

    The estimation of pollutant concentration from sources in complex terrain is something very difficult to achieve in an operational situation. In this paper, we evaluate two different approaches of wind-field modelling. The first is a fully used, mass consistent, model (MINERVE) from Aria Technologies, based on the interpolation of wind data under the constraint of minimising flux divergence. The ...

  • Validation of an operational advanced Gaussian model with the Copenhagen and Kincaid datasets

    A practical model for evaluating ground-level concentrations from elevated sources that applies a new Gaussian formulation for transport and vertical diffusion is presented. In the Gaussian formula, the source height is replaced by a virtual source height, which is expressed by simple functions of the vertical profiles of wind and turbulent diffusivity. The performances of the model are evaluated ...

The primary goal of this project is to develop a framework of advanced offshore measurements to support emergency response, oil and gas exploration ...

  • Water Plant’s Investment in GTI Covers Brings Both Operational and Safety Benefits

    The Utility: The Griswold Water Treatment Plant is part of Aurora Water, the utility that manages water and wastewater in the city of Aurora, Colorado, USA. This direct filtration plant treats 80 million gallons of water per day (302,800 m³/d). The Utility’s Needs: Originally built in 1965, the Griswold Water Treatment Plant had undergone ...

  • miniSODAR

    The miniSODAR is a high-frequency Doppler sodar system that was designed to measure the atmospheric wind profile from 15 meters to 150/200 meters (data is often available to 250 meters) in 5-meter increments. It operates by generating a short tone burst (30 ms to 100 ms) in the frequency range of 4 kHz to 6 kHz. It monitors the low-level acoustic signal echoed by the atmosphere. The echo is ...

  • Contrasting suspended covers reveal the impact of an artificial monolayer on heat transfer processes at the interfacial boundary layer

    The highly variable performance of artificial monolayers in reducing evaporation from water storages has been attributed to wind speed and wave turbulence. Other factors operating at the interfacial boundary layer have seldom been considered. In this paper, two physical shade covers differing in porosity and reflectivity were suspended over 10 m diameter water tanks to attenuate wind and wave ...

  • Coupling of neural network and dispersion models: a novel methodology for air pollution models

    Supervised neural net models and dispersion models are two important approaches for evaluating air pollution concentrations. The authors propose the development of an integrated model, in order to optimise the performances of each methodology. The concentrations evaluated by an air pollution model are coupled with a Neural Net (NN), so as to adjust the influence of important variables on ...

  • Climate Change Interview with Manchester City Football Club

    Manchester City Football Club is making history with its answer to reducing CO2 emissions. The club is building the UK’s largest land-based wind turbine that will power the stadium as well as some local residents. The project is expected to save the equivalent of the total CO2 emissions from 2,000 homes. Pete Bradshaw is social responsibility manager for the club and is in charge of the ...

  • Evaluation of dispersion model parameters by dual Doppler lidars over West London, England

    Urban dispersion models have parameters for the turbulence and mixing height. We identify the parameters in meteorological pre-processors, which are, in principle, measurable by pulsed Doppler lidar. This technique measures radial velocity from the Doppler shifted wavelengths of backscattered laser pulses. First results obtained from single and dual lidar operations are described. Using two ...

  • Potential Dispersion Modeling Uses of Archived NOAA Forecast Model Data

    A newly-developed generation of air quality simulation models has the potential to use profiles of wind, temperature, and turbulence, as well as improved mixing height determination, measures of surface heat flux, and a host of other meteorological parameters. Several numerical weather prediction models that generate these comprehensive data sets are routinely being run by the National Oceanic ...

  • Recovering oil from grinding sludge - Case Study

    Zahnradfertigung Ott uses RUF briquetting unit A large volume of sludge is produced in the grinding of high-precision gears. In most cases, this grinding sludge is disposed of at high costs. Zahnradfertigung Ott, a specialist manufacturer of gears, found a better solution: since 2005, the company is using a briquetting unit from RUF to recover 500 litres of grinding oil per day from the ...

  • Field demonstration of a near-real-time multi-metals ambient fence line monitor case study

    National emissions standards for hazardous air pollutants (HAPs) are required under Section 112 of the Clean Air Act to limit the release of specified HAPs. Permitting, monitoring and enforcement of these emission limits are an integral part of managing air quality to protect human health and the environment. However, this is difficult and highly uncertain in the case of fugitive emissions ...

  • Sahara Dust pollutes Southern Greece – this is how Lufft Ceilometers can help

    Information related to the range resolved aerosol-cloud physical properties appears to be mandatory for our better understanding of the atmospheric dynamics, air quality and climate change. Recently, the Southern part of Greece  suffered from a severe Saharan Dust outbreak. The dust had been driven across the Mediterranean due to strong south winds. The island of Crete was mostly affected by ...

  • Dispersion modeling— New downwash calculations change the playing field

    For many people, the terms “stack height” and “dispersion model” do not ring a bell. Others grapple with these terms as they can be challenging factors in the process of obtaining an air construction permit. Have you ever constructed a stack at a specific height due to EPA guidelines and regulations surrounding Good Engineering Practice (GEP) as it relates to air ...

  • Land Treatment

    Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate the ...
