New Product Coming Soon!
|
Lakes Environmental Software and its German partner ArguSoft are proud to announce the upcoming
release of ARTM ViewTM. Based on the successful AUSTAL ViewTM, this new user interface controls the
Atmospheric Radionuclid Transport Model (ARTM). ARTM is the new standard for calculating the
dispersion of airborne radioactive materials according to the German Nuclear Act. The model follows
the Lagrangian approach of AUSTAL2000.
ARTM View has been adapted and improved from the current version of AUSTAL View 5.0. For details of
the features see: www.argusoft.de/artmview.htm. A
description of ARTM is available (in English) from
BfS (German Federal Agency for Radiation Protection). Look for a release date to be announced by
the end of September! For more information about ARTM View, please contact ArguSoft in Germany (GMT+1) by email, at
info@argusoft.de, or by phone, at +49.2232.9289.448.

Monthly Modeling Tip
|
Global Use of AERMET: Upper Air Data
|
The AERMOD Modeling system was originally designed by the US EPA with US modeling in mind; while AERMOD
can successfully be used anywhere in the world, some considerations must be made.
One of the main considerations is the use of upper air data in AERMET. If upper air data is not available,
Aermet View’s Upper Air Estimator may be used. If upper air data is used, care must be taken to format
the time stamps so that they will be accepted by AERMET – this is the topic of this modeling tip.
Sounding Time
Morning upper air soundings are typically taken at 1200 GMT in the US, and AERMET is designed to expect
the morning soundings at or near this time. For many locations outside of the US, 1200 GMT does not
correspond to morning time and the morning sounding is taken at some other time. Using such upper air
data in Aermet may cause an unsuccessful run.
If morning soundings are recorded at a time other than 1200 GMT, it is recommended that they be
artificially converted to 1200 GMT in the upper air file.
Adjustment to Local Time
The Adjustment to Local Time (also know as tadjust under the LOCATION keyword) is a parameter provided
to AERMET which is subtracted from the GMT times in the upper air file in order to convert them into
local standard times. If the upper air sounding times have been artificially changed to 1200 GMT, then
the Adjustment to Local Time must also be changed so that it will convert 1200 GMT into the actual
morning sounding in local standard time.
Example
This procedure is best illustrated by an example; let’s consider a project located in Athens:
Local time zone |
GMT+2 |
Morning sounding time (local) |
0500 LST |
Morning sounding time (GMT) |
0300 GMT |
In this case, the times in the upper air file must be moved forward by 9 hours to 1200 GMT.
The Adjustment to Local Time would have been given in as “-2hr (Athens)”, but since we have shifted
the upper air times by 9 hours, we must also shift the Adjustment to Local Time by 9 hours. The
Adjustment to Local Time should be set to “7hr (Mountain)”.
We can see that if we subtract the adjustment from the upper air sounding time (in GMT) we get the
actual sounding time (is LST):
1200 GMT – 0700 = 0500 LST
With these settings, the project should run correctly.

Windmills Split Town And Families
Aug 16, 2008 - "Listen," John Yancey says, leaning against his truck in a field
outside his home. The rhythmic whoosh, whoosh, whoosh of wind turbines echoes through the air. Sleek
and white, their long propeller blades rotate in formation, like some otherworldly dance of
spindly-armed aliens swaying across the land.

Antarctic Climate: Short-term Spikes, Long-term Warming Linked To
Tropical Pacific
Aug 15, 2008 - Dramatic year-to-year temperature swings and a century-long
warming trend across West Antarctica are linked to conditions in the tropical Pacific Ocean,
according to a new analysis of ice cores conducted by scientists at the National Center for
Atmospheric Research (NCAR) and the University of Washington (UW).
The findings show the connection of the world's coldest continent to global
warming, as well as to periodic events such as El Niño.

African Firms Start To Take Action On Climate Change
Aug 15, 2008 - With global warming expected to hit Africa hard, some
companies in the "forgotten continent" are taking action themselves to fight climate change. "The
environment is not being taken very seriously in most of the emerging markets, because we haven't
started feeling the pressure yet," Adan Mohamed, chief executive of Barclays Bank Kenya, told
Reuters. "But it has got to be addressed and it is up to us corporates to lead that."

CMA Sees Sharp Rise In Air Pollution Deaths
Aug 13, 2008 – OTTAWA–The Canadian Medical Association is warning that the
number of deaths related to air pollution is set to soar, with a cumulative death toll of 800,000
Canadians by 2031. The vast majority of those deaths will be among people aged 65 years and older
because they are more vulnerable to heart problems, the group said in a study released today.
Association president Brian Day says the number of people in that vulnerable zone will grow as
the population ages.

Exports Account For One-third Of China’s Emissions
Aug 12, 2008 - As Chinese manufacturers feed a growing global appetite for cheap
goods, these exports account for a rising share of the country's greenhouse gas emissions, a new
study reveals. Exports are now responsible for one-third of China's emissions, according to a
study that will appear in the journal Energy Policy. The researchers describe their analysis as
the most systematic study of the subject to date.
