Modeling Tip
AERMOD Output: When Did a High Value Occur?
Contour plots are one of the most common forms of output from air dispersion models. They are useful in quickly identifying trends and maxima, but they also require a careful eye to ensure proper interpretation.
For example, output files generated by AERMOD and used by software programs like Lakes Environmental’s AERMOD View application for contouring (nominally the Contour Plot File) report high values from each modeled receptor. For short-term averaging periods (i.e., 1-hour, 24-hour, Month, etc.), these high values may occur at different times during the modeled period. This means the short-term Contour Plot File are time-independent.
You can find when a high value occurred in the model run by reviewing the Contour Plot File. AERMOD View includes a utility called the Plot File Grid View to make this information easier to read. Here is how you can access the Plot File Grid View.
Step 1: After a successful model run, navigate to the Plots tree menu.
Step 2: Select the plot file of interest. Plot files are sorted by source group, high value, and averaging period.
Step 3: Select the Grid View button from the tree menu to open the Plot File Grid View.
Step 4: Scroll to the right to locate the Date column. You can now verify the date and time at which the concentration was modeled.

Taiwan EPA Tightening the Rules Surrounding Air Pollution
March 3, 2015 - TAIPEI -- Environmental regulations on the country's emissions of air pollutants will be stricter in light of deteriorating air quality, the Environmental Protection Administration (EPA) said Monday.
Starting next year, supervision of factories planning for expansions will be tighter, including demands for data on possible increases in particles 2.5 microns or smaller in diameter (PM2.5), according to the EPA.
Air Pollution Will Kill Thousands in Europe, EEA Warns
March 3, 2015 - Hundreds of thousands of Europeans will suffer a premature death in the next two decades as the result of governments’ failure to act on air pollution, Europe’s environmental watchdog has warned.
“In 2011, the latest year for which figures have been reliably collated, more than 400,000 are estimated to have died prematurely as a result of breathing toxic fumes, despite recent improvements in some countries
EPA Approves New Climate-Friendly Refrigerants
March 2, 2015 - WASHINGTON - As part of President Obama’s Climate Action Plan, the U.S. Environmental Protection Agency (EPA) is increasing the options for refrigerants used in various kinds of refrigeration and air conditioning equipment in the United States that offer better climate protection without harming the ozone layer. This final action addresses refrigerants under the Climate Action Plan that calls on EPA’s Significant New Alternatives Policy (SNAP) Program to identify and approve additional climate-friendly chemicals.
“Today’s rule is an example of how we can turn the challenge of climate change into an opportunity to innovate our way to a better future,” said EPA Administrator Gina McCarthy. “By working together, businesses and EPA are bringing new, climate-friendly refrigerants to market that better protect our health and the environment.”
Despite New Standards, High Levels of Carcinogens Remain in Hamilton Air
February 27, 2015 - Hamiltonians are breathing air contaminated by two carcinogenic chemicals at levels significantly higher than the Ministry of Environment’s incoming air standards – and it’s going to stay that way for years.
These airborne culprits are well known in Hamilton: benzo[a]pyrene and benzene. Both can cause leukemia and other cancers.
South Africa Companies Guilty of Air Pollution Get a Five-year Reprieve
February 24, 2015 - TThe environmental department has given most of South Africa’s polluters a reprieve of up to five years to comply with air quality legislation.
The department of environmental affairs today released a list of heavy polluters that would be given postponements for complying with air quality legislation. Environmental and social groups have said the exemption is tantamount to granting the polluters a “licence to pollute” and “making toxic air legal”.
U.S. Embassies are Going to Measure Other Countries’ Air Quality
February 19, 2015 – In 2008, American diplomats in Beijing quietly installed an electronic monitor outside the U.S. Embassy to test pollution levels in the Chinese capital’s famously sooty air. The results, posted daily on the Internet, were mainly intended for U.S citizens and visitors, but soon ordinary Chinese were logging in for reliable information about health threats in the air they breathed.
Chinese officials complained, but the daily reports from the embassy’s monitor added to the pressure that eventually led China to take dramatic steps to reduce smog. It worked so well, in fact, that the Obama administration has now decided on a major expansion — to U.S. diplomatic missions all around the world.
