  • ADMLC report on dispersion from agricultural sources published

    ‘A review of the limitations and uncertainties of modelling pollutant dispersion from non-point sources’ was published earlier this year. This report presents a detailed literature review, including a summary of agricultural and bioaerosol source parameter ranges particularly of interest to those modelling multiple releases from low-level sources in the vicinity of farm sheds. Results ...

  • Air pollution monitoring model takes off in Australia

    “The Air Pollution Model (TAPM) increases our ability to pinpoint pollutant behaviour in a wider range of atmospheric conditions,” says CSIRO’s Dr Peter Hurley. ”Over the coming years the new model will continue to fill a gap between simple air pollution dispersion models and the much more complex earth system models such as The Australian Community Climate and Earth-System Simulator (ACCESS).” ...

  • Mexico City the Model Megacity for Pollution Study

    As one of the world's biggest urban sprawls and home to some of the planet's worst pollution Mexico City makes the ideal subject for a science experiment on a grand scale. Mexico City A team from the USA's National Centre for Atmospheric Research (NCAR) will be leading one of the most complex research projects ever to look at atmospheric chemistry to track the changes in air pollution as ...

  • TOXFLAM online

    TOXFLAM is a software code based on an analytical solution to the atmospheric dispersion equation for inert substances that may undergo a first-order chemical or physical decay and have a density that is similar to the air density (Bianconi and ...

  • CERC at the recent Harmo conference in Budapest

    Two of our team, Managing Director Dr David Carruthers and Stephen Smith, recently attended the 17th Harmo conference in Budapest. This conference aims to harmonise approaches to atmospheric dispersion modelling and model evaluation. They presented work on ...

  • 2006, a key year for GEOVARIANCES in the nuclear sector

    The past year is characterized by the strong development of our activity in the nuclear sector. Notably, several licenses of ISATIS have been acquired by CEA (French Atomic Energy Authority) in France, ONDRAF (Belgian Agency for Radioactive Waste and Enriched Fissible Materials) in Belgium and JRC Ispra in Italy. GEOVARIANCES has also been involved in pilot studies, ISATIS training courses and ...

  • Ramping up our POPs monitoring role

    As a Party to the Stockholm Convention on Persistent Organic Pollutants, Australia and 172 other countries are committed to eliminating or restricting the production and use of a range of chemicals that pose a major, long-term threat to humans and the environment. CSIRO atmospheric scientist, Dr Melita Keywood, said POPs typically have the ability to: remain intact in the environment for long ...

  • ESRL helps develop a response system for airborne threats

    ESRL’s Rich Jesuroga pulled up a map of Fort Worth, Texas on his computer, and clicked the mouse once in a suburb. “Suppose there’s a toxic release here,” he said. Within one minute, Jesuroga, a researcher in ESRL’s Global Systems Division, learned that prevailing conditions would swirl the imaginary airborne toxin west. Within two minutes, he traced a polygon over the “hottest” part of the ...

  • GEOVARIANCES more than ever involved in nuclear safety

    GEOVARIANCES activity in nuclear sector was initiated in 2004 with the acquisition of several ISATIS licenses by CEA (French Atomic Energy Authority), ONDRAF (Belgian Agency for Radioactive Waste and Enriched Fissile Materials) and JRC Ispra in Italy.Besides, GEOVARIANCES conducted pilot studies, training courses and on-site technical support. Tackled issues have been numerous: characterization ...

  • Fact sheet on NCAR simulations

    The simulations released today show the potential for oil to reach the Atlantic at some point in the future, but don"t project when, where or whether any of it would make landfall or at what concentrations.  Because of the effect of dispersants, mixing, and a range of other biological and physical factors, any oil that reaches the Atlantic would be at a much lower concentration.  ...

  • BREEZE Software Presents a Comparison Study in Response to the Proposed Replacement of CALINE3 with AERMOD in Appendix W

    The U.S. EPA has proposed a number of revisions to the Guideline on Air Quality Models, published as Appendix W to 40 CFR Part 51 (Appendix W) in 2005, many of which are discussed in depth here. The proposed revisions include a large amount of new material as well as the ...

  • Forest fires increase mercury emissions

    Mercury is a global pollutant arising from many sources, including biomass burning (BMB), which includes both wildfires and intentional fires to clear land. A recent study estimates that mercury emissions from BMB make up 8 per cent of total global mercury emissions. Mercury emissions from BMB have received growing attention. Forests in particular act as mercury sinks because atmospheric mercury ...

  • New tool could aid safe underground storage of CO2, says MIT

    To prevent global warming, researchers and policymakers are exploring a variety of options to significantly cut the amount of carbon dioxide that reaches the atmosphere. One possible approach involves capturing greenhouse gases such as carbon dioxide at the source -- an electric power plant, for example -- and then injecting them underground. While theoretically promising, the technique has never ...

  • Fertilize the ocean, cool the planet?

    Original story at MIT News Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting it to carbohydrates and oxygen. Many phytoplankton species also release dimethyl ...

  • On-site water treatment service from Tangent Environmental Technologies cuts costs
