The supported files include EPA AERMOD and ISC input files (.dat), BREEZE AERMOD input files (.ami), source files (.pnt), receptor files (.rec), and building files (.bld). With these file types, users can import model object data including, but not limited to, locations, exit ...

  • What is Indoor Air Quality?

    Indoor Air Quality (IAQ) refers to the degree of air purity inside buildings that constitute the usual environment in which people carry out activities (offices, homes, schools, shopping and leisure centres, etc.) Because of increasing urbanisation and our contemporary lifestyle, most people spend a large proportion of their time in these closed environments. The high level of atmospheric ...

  • Incentives for aviation biofuel have a limited role in decarbonisation of air travel

    While it was once hoped that biofuel would be a game-changer for transport emissions, evidence has since emerged of unwanted effects from biofuel production, including direct effects such as deforestation to grow biofuel crops, and ‘Indirect Land Use Change’ (ILUC) effects such as the use of previously forested land for agriculture (if agricultural land is used) for biofuel. Recent ...

  • What is Indoor Air Quality and How Can You Improve It?

    For the longest time, air quality was meant to refer to the quality of air circulating outdoors. However, indoor air or the air found inside and around homes and office buildings is just as important to pay attention to. Improving indoor air quality should be a priority for everyone.  What is Indoor Air Quality? Indoor air quality is the quality of air found circulating ...

  • Modeling Tip: How to Import BREEZE AERMOD files into BREEZE Risk Analyst for Human Health Risk Assessments

    Humans can be exposed to hazardous air pollutants (HAPs) either directly through inhalation or indirectly through ingestion or dermal contact, which can result in acute or chronic health effects. The risk of exposure varies depending on a number of variables, including the meteorological conditions, local geographical and emissions characteristics, the age of the individuals being exposed, and ...

  • Optimization of atmospheric air plasma for degradation of organic dyes in wastewater

    This study optimises the degradation of a cocktail of the dyes methyl orange and bromothymol blue by atmospheric air plasma. Response surface methodology (RSM) was employed to investigate the efficacy of the plasma process parameters on degradation efficiency. A Box–Behnken design (BBD) was employed to optimise the degradation of dyes by air plasma discharge. A second order polynomial equation ...

  • Landfills have a huge greenhouse gas problem. Here’s what we can do about it.

    We take out our trash and feel lighter and cleaner. But at the landfill, the food and yard waste that trash contains is decomposing and releasing methane, a greenhouse gas that’s 28 times more potent than carbon dioxide. Landfill gas also contributes to smog, worsening health problems like asthma. Globally, trash released nearly 800 million metric tons (882 million tons) of ...

  • 4 Signs Of Poor Indoor Air Quality To Watch For

    The quality of indoor air is something most of us take for granted. Unless there is something very specific and unusual going on around us, like heavy cleaning or maybe new construction, we don’t often think about whether or not there is anything wrong with the air we breathe as we go about our daily business. The truth is, though, that indoor air quality is often worse than ...

  • Modeling Tip: How to Merge BREEZE Remote Modeling System’s Results with the Local .AMZ File and View Results in BREEZE AERMOD

    The BREEZE Remote Modeling System (BRMS) is a Web-enabled application that executes AERMOD model runs in a fraction of the time they take on a desktop computer, thereby assisting modelers in reducing model runtimes on large or highly time-sensitive AERMOD model runs. The BRMS operates on a massively parallel computer cluster that ...

  • 5 Things You Probably Didnt Know About Indoor Air Quality

    Did you know that air fresheners, candles, furniture, carpets & many other items create indoor air pollutants and are a health risk says Camfil Air Filtration Experts! When you mention air pollution, most people automatically think of smog around cities and factories, or millions of cars racing from one place to another leaving trails of fumes behind them as they ...

  • Air Conditioning That`s Out of This World

    New materials enhance the cooling effects from outer space to reduce energy use in small- to medium-sized buildings Reducing air conditioning energy use by using new materials to enhance the cooling effects from outer space may not be such a far-out idea. In a simulation study using DOE's Energy Plus software and ...

  • How to Get Higher Acceptable Indoor Air Quality Anywhere

    The quality of the indoor air we breathe is a concern for everyone, especially those in urban environments where contaminant and particle levels are higher due to nearly constant exposure to things like automobile and truck exhausts, construction, and fumigation. Unfortunately for most people, when it comes to the quality of the air in the buildings where they spend most of their time, ...

  • Modeling Tip: Importing a Map Image File into BREEZE AERMOD or 3D Analyst

    Imported maps can be very helpful when setting up a model scenario and analyzing the results. They can be used as a QA/QC method for ensuring that model objects are in the correct locations and they can also help better visualize results graphically. Although a map file is not required, BREEZE ...

  • Paris Climate Change Agreement: What next?

    The Paris Climate Change Agreement took a huge leap forward on 3 September when the world's two biggest economies and emitters of greenhouse gases – the USA and China – announced that they would formally ratify the accord. This brings hope that the deal will be concluded this year. It also piles pressure on the UK to swiftly formalise its commitment to a contract it shaped ...

  • Modeling Tip: Batch Scheduling and Restart Options in BREEZE AERMOD for Large Modeling Runs

    Although the advanced physics in U.S. EPA’s AERMOD more accurately represent dispersion of pollutants in the atmosphere, it comes with the disadvantage of greatly increased model run times. Even for a comparatively small project containing a few thousand receptors and a dozen sources, the runtimes can last longer than an hour. This makes the scenario where dozens of runs need to submitted ...

  • Modeling Tip: How Parallel Processing can Expedite Large AERMOD Model Runs

    Due to advances in scientific knowledge, higher resolution raw data, stringent air quality standards, and changing regulations, environmental modeling is demanding more and more from EHS professionals and their computers. All of these influences have resulted in significantly longer AERMOD model run times as compared to the predecessor regulatory model, ISCST. Instead of minutes, AERMOD runtimes ...
