During the EPA’s 9th modeling conference, it was announced that there will soon be a release of all
three components of the AERMOD modeling system (AERMET, AERMAP and AERMOD) dated 08280. The following
updates are expected to be included in the release:
- Models compiled in Intel Fortran compiler (40% runtime improvement)
- Additional variable emission scenarios
- AERMAP issues with Alaskan DEMs corrected
- Support for NED elevation data
- Mixed DEM support
- User-specified upper air sounding window
- Double precision used for most non-integers
- OLM group bug fixed
- Miscellaneous bug fixes and features
For full details, you can view all of the presentations from the 9th modeling conference on the
EPA’s SCRAM website:

Monthly Modeling Tip
|
Interpreting Contours Part 2: Location of Maximums
|
In this tip, the second in a series about interpreting contours, we will consider the location of
maximum concentrations.
Commonly, people assume that the maximum concentrations will be located downwind of their source(s)
in the direction of the prevailing wind. While this can often be true, it is not always the case,
as can be seen below:
There are two factors that can cause this:
- If a short term average is being considered, it is the highest concentration that is important,
not the frequency of high concentrations. For a one hour average, it only takes a single hour to
have the highest concentration; this single hour may have a wind direction other than the
predominant one.
- Factors other than the direction of the wind affect concentrations; if the wind is typically
blowing at a high speed in the predominant direction, this will lead to lower concentrations. If
wind blowing in other directions causes building downwash, this will lead to higher concentrations.
While it is not uncommon to have the highest concentrations in the direction of the predominant
wind, you can see from the reasons above that it is not unreasonable for the opposite to be true.

Remember: We are currently accepting
submissions for the Monthly Modeling Tip that appears in
our newsletters. If
you have a modeling tip that may benefit a variety of people,
please send it to us at support@weblakes.com.
Your name and the name of your organization will appear below
the tip providing you with greater exposure.

Coal Plant Permits on Hold Over Warming Gases
Nov. 14. 2008 - WASHINGTON - The fate of scores of new coal-burning power
plants is now in limbo over whether to regulate heat-trapping greenhouse gases.
The uncertainty resulted when an Environmental Protection Agency appeals
panel on Thursday rejected a federal permit for a Utah plant, leaving the issue for the Obama
administration to resolve.
The panel said the EPA's Denver office failed to adequately support its
decision to issue a permit for the Bonanza plant without requiring controls on carbon dioxide,
the leading pollutant linked to global warming.

Coal to Remain World's Top Power Source: IEA
Nov. 14, 2008 - LONDON (Reuters) - Coal, which produces more climate-warming
carbon dioxide than oil or gas, will remain the world's main source of power until 2030 and
nuclear will lose market share, the International Energy Agency said on Wednesday.
Expectations of slower economic growth have led the IEA to downgrade its 2030 world
electricity demand forecast to 23,141 terawatt hours (TWh), but the share of coal generated
power would rise to 44 percent by 2015 from 41 percent in 2006.

Giant Asian Smog Cloud Masks Warming Impact: U.N.
Nov. 13, 2008 - BEIJING (Reuters) - A three-kilometer thick cloud of
brown soot and other pollutants hanging over Asia is darkening cities, killing thousands and
damaging crops but may be holding off the worst effects of global warming, the U.N. said on
Thursday.
The vast plume of contamination from factories, fires, cars and
deforestation contains some particles that reflect sunlight away from the earth, cutting its
ability to heat the earth.

Study: Calif. Dirty Air Kills More Than Crashes
Nov. 13, 2008 – FRESNO, Calif. - Lowering air pollution in Southern
California and the San Joaquin Valley would save more lives annually than ending all motor
vehicle fatalities in the two regions, according to a new study.
The study, which examined the costs of air pollution in two areas with
the worst levels in the country, also said meeting federal ozone and fine particulate
standards could save $28 billion annually in health care costs, school absences, missed work
and lost income potential from premature deaths.

Canada Ranks Low on Environment
Nov. 11, 2008 - LOBE-Net (November 11, 2008) - Canada’s environmental
performance fares poorly when compared to 16 other developed countries, according to a report
by the Conference Board of Canada. Canada placed 15th overall, beating out only Australia and
the United States. The Nordic countries swept the podium with Sweden holding top spot,
followed by Finland and Norway.
One reason why Canada, Australia and the United States are at the bottom
of the list is because these countries are geographically large and resource intensive.
Extracting and processing minerals often requires lots of water. Greater distances means
greater amounts of energy required to transport people and goods, leading to more greenhouse
gas emissions.
