  • Modelling dispersion of smoke from wildfires in a Mediterranean area

    We present a modelling system for the estimation of forest fire emissions ( prebolchem-fire ) and their inclusion in the atmospheric composition model BOLCHEM. Emission fluxes have been estimated following the methodology proposed by Seiler and Crutzen (1980) and using MODIS ‘burned area product’. Then they are modulated following the WRAP approach (WRAP, 2005). This approach is also used for ...

  • Numerical simulation of aerosols in an aircraft wake using a 3D LES solver and a detailed microphysical model

    The global impact of aviation on the atmosphere is generally determined using the total amount of gas and particulate matter emitted at the aircraft engine exit but generally ignore some of the physical transformations occurring at much smaller scales in the aircraft wake. In this work, we present an offline alternative method based on the use of a detailed plume aerosol model combined to fluid ...

  • The Important Job of Oil Mist Collectors

    The majority of business owners whose manufacturing process requires machinery that uses coolants, lubricants, or oils know how vital it is to keep the spray or mist released, during the operation from collecting on walls, ceilings or floors as much as possible. Emissions that are uncollected, can lead to slippery surfaces and an unhealthy working environment, which is why an  ...

  • Variations in tropospheric submicron particle size distributions across the European continent 2008–2009

    Cluster~analysis of particle number size distributions from~background sites across Europe~is presented. This generated a total of nine clusters of particle size distributions which could be further combined into two main groups, namely: a south-to-north category (four clusters) and a west-to-east category (five clusters). The first group was identified as most frequently being detected inside ...

  • Towards the simulation of size-resolved aerosol over Europe: model and observations

    Knowledge of the number density and size distribution of atmospheric aerosols in the submicron size range is essential for estimation of the aerosol radiative effects and the health impact of particles. Ultrafine particles (UFP), i.e. particles with diameters <100 nm, have received increased attention in recent years with improved possibilities of measuring them. UFP originate from nucleation, ...

  • Spatial and temporal variations of nitro-polycyclic aromatic hydrocarbons in PM 2.5 aerosols in Yangtze River Delta Region, China

    Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) are of great interest because of their high potential mutagenicity and carcinogenicity. PM 2.5 aerosol campaigns were carried out for four seasons from December 2007 to January 2009 in Xujiahui, Baoshan and Lin’an in Yangtze River Delta Region, China. Nine nitro-PAHs were detected, the average seasonal concentrations for three sampling ...

  • Sensitivity of ozone and aerosols to precursor emissions in Europe

    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%. On the other hand, the effect on secondary organic aerosols (SOA) was very small. Reductions in ...

  • Large eddy simulation modelling of the dispersion of radioactive particulate matter

    Field experiments with a Radioactive Dispersion Device (RDD) were performed by the National Radiation Protection Institute (NRPI) of the Czech Republic. We present the results of computer simulations of these experiments using a new microscale model, Charles University Large Eddy Microscale Model (CLMM). The model was first validated using wind tunnel data for the dispersion of continuous passive ...

  • `South Asian monsoon variations hard to fathom`

    Understanding how the South Asian monsoon will change in response to global warming  and resolving the uncertainties in projected changes are ‘demanding tasks’ for climate science, a review says. Current state-of-the-art general circulation models have difficulty simulating the regional ...

  • Source apportionment technique: inorganic aerosol transformation processes in the Milan area

    The CAMx chemical and transport Eulerian model has been applied over a domain focused on the Milan area (Northern Italy) for the whole 2004, on the basis of CityDelta III project input data set. Model results have been analysed by mean of the Source Apportionment technique at the Milan receptor. A quantitative analysis of the main processes governing the Secondary Inorganic Aerosols (SIAs) ...
