The ABEC Air Quality Initiative shows that with the right tools and commitment, we can combat the invisible killer that is air pollution - learn how air quality sensors are used in Almaty & ...
The Canadian city of Sherbrooke deploys fixed and portable air quality monitors TERA Group won the call for technological innovation projects launched by the City of Sherbrooke as part of its Validation of Pilot Technological Innovations (VITE) program. ...
The Canadian city of Sherbrooke deploys fixed and portable air quality monitors TERA Group won the call for technological innovation projects launched by the City of Sherbrooke as part of its Validation of Pilot Technological Innovations (VITE) program. Microsensors implementation for a clearer picture of air quality in real time Under this VITE program, ...
As part of the California Air Resources Board (CARB) AB617 Community Air Monitoring Program, Clarity deployed a 50-sensor network in Richmond, California with Groundwork Richmond and Ramboll SHAIR. The network is used to evaluate pollution sources and hotspots in the industrial city, as well as engage community members in environmental ...
Different modelling approaches are used to design and assess air quality plans across Europe. ...
We propose non–linear models to study the feasibility of removing CO2 from the atmosphere by introducing some external species such as liquid droplets and particulate matters in the atmosphere, which may react with this gas and get it removed by gravity. ...
Coal dust is a major cause of air pollution in areas around opencast coal mining sites. Prediction of ambient concentration of pollutant should be known to implement any control techniques or to install any control equipment. ...
Different operational air quality forecasts (ESSEM Cost Action 0602) are currently available in Europe. However, most of them are not suitable for regional application and, also, their coarse outputs do not fit well with air quality management needs. In this work, PRESAXIO regional air quality modelling system is validated and ...
A dispersion model for continuous releases of pollutants in the atmospheric boundary layer is applied to study the influence on modelled concentrations of different estimates of the key micrometeorological variables that represent the dispersion processes. The modelling approach is based on the advection-diffusion equation and ...
This study presents the performances of an inverse modelling approach aiming to identify position and emission rate of a localised pollutant source placed within a city district. To that purpose we combine wind tunnel experiments and an urban dispersion model. Experiments are performed in an idealised urban canopy, made up of regularly spaced ...
The last decade, scientific studies have indicated an association between air pollution to which people are exposed and wide range of adverse health outcomes. We have developed a tool which is based on a model (MM5-CMAQ) running over Europe with 50 km spatial resolution, based on EMEP annual emissions, to produce a short-term forecast of the ...
Slovenia is a country of very complex terrain and many problems with air pollution in the valleys, canyons and basins, where industrial air pollution is combined with traffic and domestic heating air pollution, giving rise to problems for the health impact and the ecosystems directly or ...
Dispersion models can be a useful tool for reproducing spatio-temporal distribution of contaminants emitted by a specific source. ...
The method used for the PM10 source apportionment in 18 air quality management areas (AQMAs) in Slovakia is presented, as well as the results of the study. Local PM10 emissions include traffic emissions, local seasonal heating sources from residential housing, industrial and point sources, and fugitive sources. Mathematical modelling has been performed using ...
The paper presents fully operational air pollution prediction and doses calculation system working in 2/24/7/365 mode for more than a decade in Krško Nuclear Power Plant (NPP). ...
The problem under consideration is of great importance when modelling results, obtained after running large-scale air pollution models, have to be compared with experimental data. ...
This road traffic is the main source of air pollution, followed by industry and waste combustion. An application of the new road traffic emission model, called EMISENS, is performed to build road traffic emission inventories for the Algiers region. These emission inventories are then used as input to the MM5/CHIMERE system to estimate ...
Under real circumstances, however, operation (power setting, time-in-mode and fuel flow rate) and meteorological (air temperature, humidity and pressure) conditions may vary from ICAO definition, consequently deviation from the certificated emission indices may occur. The TURBOGAS emission model was developed for assessment aircraft engine emissions with taking ...
Air pollution has temporal and spatial variability. Time series analysis is commonly used to evolution of air pollutants in time. ...
Three sets of CMAQ model simulations were performed for a high air pollution episode from October 9 to October 12, 2004 over the Pearl River Delta (PRD) region, which was caused by a high-pressure system. The observations at Guangzhou urban site (113.26°E, 23.13°N) were used to evaluate the results of meteorological models and ...
