Lakes Environmental Software developed Char View for the U.S. EPA to allow modelers to prepare site data, emissions, inventories, and air models quickly while avoiding common human errors in the ...
Act on site-generated emissions to maintain compliance | EVS Omnis Moreover, industrial sites that monitor environmental parameters such as air quality and odour also benefit from capabilities such as reverse trajectory modelling. Users can instantly run reverse trajectory modelling techniques to accurately track the source of ...
Different modelling approaches are used to design and assess air quality plans across Europe. ...
Industrial sources, traffic, domestic heating and harbour emissions have been taken into account. Modelling system includes 3-dimensional meteorological models SWIFT-SURFPRO with the Lagrangian particle dispersion model SPRAY. The air emissions inventory was partially established using measured ...
Additionally, the use of microsimulation traffic modelling in conjunction with an instantaneous emissions model (IEM) has been adopted to allow comparison between methodologies and enable congestion sensitive analysis of the impact of air quality management measures on the network. Findings from microscale ...
Dispersion models can be a useful tool for reproducing spatio-temporal distribution of contaminants emitted by a specific source. ...
During last decade a lot of investigations also focused on the evaluation of aircraft engine impact on local and regional air quality in the vicinity of the airport. The emission inventory of aircraft engines are usually calculated on the basis of certificated emission indexes, which is provided by the engine manufacturer and reported in the ...
We modelled the air quality in Europe during January and June 2006 using the MM5/CAMx model system and studied the sensitivity of ozone and aerosol formation to precursor emissions. Increased isoprene emissions by a factor of four in summer caused an increase in afternoon ozone by up to 10%. ...
In the framework of the Interreg–IV 'PM–Lab' project a local–scale exercise was set up to evaluate air pollution in terms of particulate matter (PM) within the centre of Liège, Belgium (pop. 190,000). ...
Two urban street canyon models, STREET and OSPM, were investigated at Pearse Street, in the centre of Dublin City. ...
This study explores for the first time, the applicability of the Danish Operational Street Pollution Model (OSPM) in the city of Buenos Aires where street canyons are very irregular. The model is applied in an irregular and asymmetric street canyon of a five–lane avenue near a street intersection. ...
In this work, a Lagrangian particle model able to account for simple chemical reactions between NO and O3 has been improved to consider the photolysis of NO2. A system of chemical equations is numerically solved on a Eulerian grid, while the particle trajectories are moved in a Lagrangian frame. The NOx emissions of a power plant in real atmosphere, situated in a ...
A CALMET–CAMx system was implemented to investigate PM10 source apportionment in the urban area of Venice. The modelling system was run for two winter months on a domain covering most of the Veneto region with a 4 km resolution mesh and a 1 km nested grid over Venice and its mainland area, in order to distinguish the local emission contributions from the regional ...
One method to assess the source contribution of particulate matter to urban air quality is through inverse modelling where emissions are estimated using dispersion models and monitoring data. In this paper, a straightforward inverse modelling method, using Multiple Linear Regression, is described and applied to ...
WRF–ARW/HERMES/CMAQ modelling system is applied with high resolution (1 km², 1 h) to assess changes in Madrid and Barcelona (Spain) air quality due to hybrid cars introduction. ...
In such a situation it is important to use Chemical Transport Models (CTMs), to properly describe phenomena bringing to pollution formation and accumulation. Meteorological models are one of the drivers of CTMs and, due to their complexity, require high computational costs to be run. Within the HPC–EUROPA (Pan–European Research Infrastructure on High Performance ...
The factors affecting ground level ozone concentrations in the Greater Athens Area (GAA) are examined through adjoint sensitivity analysis, using a meteorology and air quality forecasting system based on MM5, the in–house EMISLAB emissions processing system and the chemical transport model Community Multiscale Air Quality (CMAQ). ...
The air-quality modelling system was conducted to evaluate emissions inventory and simulate air concentration over Thailand. ...
ADMS-Airport is based on the ADMS-Urban system for modelling urban air quality. In the near field it employs a quasi-Gaussian dispersion model and this is nested within a trajectory model. ...
The numerical simulations are carried out using the MODELS-3 nesting abilities, downscaling to a horizontal resolution of 10 km, the innermost domain including a region with very intensive road transport – the city of London and its 'footprint'. A large number of numerical experiments were carried out, which makes it possible to distinguish the relative contribution of different ...
