EPA releases air quality model to study harmful air pollution / model will help scientists protect public health
The U.S. Environmental Protection Agency (EPA) released a new version of its Community Multi-scale Air Quality model (CMAQ) that uses up-to-the minute meteorology and air chemistry data to determine how weather conditions affect pollution, and how pollution can affect and change weather. Version 5.0 of CMAQ allows scientists to analyze air quality at smaller, finer-resolution settings for ...

Mediterranean capital pollution has far-reaching effects on air quality
New research has modelled the impacts of Athens and Istanbul in the eastern Mediterranean, on local and regional air quality. Results indicate that the impacts of megacity pollution vary significantly according to the time of year and that air quality improvements will require coordinated efforts within the eastern Mediterranean region and beyond. Megacities (cities with more than 10 million ...

Modeling the unequal benefits of U.S. environmental policy
Original story at MIT News One of the two top air pollutants in the U.S., ground-level ozone is harmful not only to your health but also to your bank balance. Long-term exposure to high concentrations of ozone can lead to respiratory and lung disease such as asthma, conditions that drive up medical expenses and sometimes result in lost income. Ozone exacts a particularly heavy toll on people ...

Counting the cost of ozone pollution on crops
A recent study has calculated crop losses as a result of surface ozone pollution. The study suggests that future earnings will be significantly reduced by ozone damage to crops, especially for some developing and agriculture-dependent countries. Surface ozone is an air pollutant that forms as a result of chemical reactions between other pollutants, particularly emissions from motor vehicles and ...

EPA Awards More Than $4.3 Million in Partnership with NSF and NOAA for Climate and Air Quality Research
Today the U.S. Environmental Protection Agency (EPA) announced more than $4.3 million in grants to 13 institutions to study and improve our understanding of how certain organic compounds form in the atmosphere. Research performed by grantees will help the federal government improve its air quality management systems and climate change models with respect to organic aerosol formation and help EPA ...

NASA Finds Sea Ice Decline Driving Rise in Arctic Air Pollutants
Drastic reductions in Arctic sea ice in the last decade may be intensifying the chemical release of bromine into the atmosphere, resulting in ground-level ozone depletion and the deposit of toxic mercury in the Arctic, according to a new NASA-led study. The connection between changes in the Arctic Ocean's ice cover and bromine chemical processes is determined by the interaction between the salt ...

Satellite data to deliver ‘state-of-the-art’ air quality information
The European Environment Agency has finalised an agreement with an ESA-led consortium to provide unparalleled information on air pollution, which contributes to the premature deaths of hundreds of thousands of Europeans annually. Under the agreement, the European Environment Agency (EEA) will use a service, which combines and processes satellite data with surface measurements from 29 European ...

Poor Air Quality Expected along the Southern Coast of New England Tomorrow (Wed. July 29)
Poor air quality, due to ground-level ozone, is expected tomorrow, July 29, in much of southern coastal New England. Air quality modeling and forecasting predicts high levels of ozone in the Connecticut counties of Fairfax, New Haven, Middlesex and New London, in coastal Rhode Island, and along southeastern Massachusetts, including Cape Cod and the Islands. Unhealthy air quality is forecasted ...

Lessons from Gothenburg on setting air pollution ceilings
The 2010 deadline for the Gothenburg Protocol ceilings for transboundary air pollutants is fast approaching and new ceilings may soon be set for 2020. Recent research indicates that, although the ceilings have been effective, they could benefit from more flexibility to allow for the inherent uncertainty in modelling future energy use, technologies and growth. The UN Gothenburg Protocol to abate ...
