Export to Google EarthTM - Coming Soon!
|
Lakes Environmental Software development team is
working on new versions of its popular air dispersion modelling
software packages: AERMOD
ViewTM, CALPUFF
ViewTM, AUSTAL
ViewTM and the new ARTM
ViewTM.
One exciting new feature is the Export to Google Earth option,
which allows you to export layers from your project, including
buildings, sources, and results, to a KML file for visualization
in Google Earth.
This functionality will be included as a standard feature,
at no extra cost, on upcoming releases of these products.
|
Sample Google Earth files, exported from Lakes Environmental
applications, are available on our website. See how this
will enhance your modeling project!

Monthly Modeling Tip
|
On-Site Data in AERMET
|
The on-site data option in the US EPA AERMET model allows you to use data collected at an on-site
meteorological tower, either in conjunction with a National Weather Service (NWS) hourly surface
meteorological file or instead of it.
On-Site Data with an NWS Surface File
If you specify both on-site data and an NWS surface file, your on-site data may contain as many or as few
parameters as you wish. Parameters from the on-site data will be used in preference to the NWS surface data
but if an onsite parameter is missing for a given hour, or if the on-site data is insufficient for AERMET to
run, the NWS data will be used as needed.
On-Site Data Instead of an NWS Surface File
If the on-site data contains sufficient information, it may be used instead of an NWS file. In this case,
the on-site file must meet certain minimum requirements in order for AERMET to run successfully. The
on-site data could contain the same minimum parameters that are required for NWS data (on-site parameter
name in brackets):
- Wind Direction (WD01)
- Wind Speed (WS01)
- Temperature (TT01)
- Sky Cover/Cloud Cover (TSKY)
If cloud cover is not available, it is also possible to use the Bulk Richardson method, which uses a two
level temperature difference for night time stability and insolation or net radiation for day time
stability. Note that the temperature difference must be provided explicitly as a difference rather than as
two temperature values. When the Bulk Richardson method is used the minimum requirements are:
- Wind Direction (WD01)
- Wind Speed (WS01)
- Temperature (TT01)
- Insolation (INSO) or Net Radiation (NRAD)
- Temperature Difference (DT01)
|
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.

Allergies Getting Worse? Blame Global Warming
Sept 15, 2008 - One of the few potentially positive effects of climate change, at
least in the short term, is that increased concentrations of carbon dioxide in the atmosphere may
enhance the growth of plants. That could be good for agriculture - though warming temperatures and
changing rain patterns in a warmer world might wipe out that advantage. But there are no unalloyed gifts
from climate change. Recent research suggests that global warming will also exacerbate respiratory
allergies, as higher CO2 concentrations lead to vast increases in ragweed pollen production. "There's no
denying there's a change," says Paul Ratner, an immunologist with the American College of Allergies.
"It's definitely bad news for people who have allergies."

Lowest Ever Sea Ice in Arctic
Sept. 15, 2008 - Declining ice thickness and what is looking like the second lowest
coverage on record means that Arctic sea ice may well have reached its lowest levels ever in terms of
total volume.
Final figures on minimum ice coverage for 2008 are expected in a matter of days,
but they are already flirting with last year’s record low of 1.59 million square miles, or 4.13 million
square kilometres.

African Renewable Energy Gains Attention
Sept. 12, 2008 - The potential for renewable energy development in Africa is
experiencing an increase in attention lately as investors and world leaders seek a new clean energy
frontier.
The continent could become a gold mine for renewable energy due to abundant solar
and wind resources. But roadblocks to clean energy worldwide are amplified throughout the troubled
regions of Africa - financial resources are thin and infrastructure is often unreliable.

New Battle Over Arctic Oil Plans
Sept. 11, 2008 – The grey waters of the Arctic Ocean are the scene for a new
battle over plans for a huge expansion in the drilling of oil and gas far beyond the Alaskan
shore.
With the Arctic ice-cap melting far beyond average for the second year running -
and with US petrol prices above $4 per gallon - there's growing pressure to exploit the reserves
beneath the seabed.

The 'Greening' of America's Two Biggest Ports
Sept. 9, 2008 - America's ports are not generally thought of as the most ecologically advanced places on the planet. But a green wave is lapping at their shores. This summer, officials at the polluted twin ports of Los Angeles and Long Beach began a program to convince container-ship captains to wean their engines off dirty-burning "bunker fuel" and instead use relatively clean marine diesel oil while idling in port. Up until recently, that hasn't been an easy sell. While marine diesel has just one tenth the sulfur, it costs an extra $650 a ton. That can add up quickly, especially during a typical three-day port of call. As an incentive to participate in their alternative-fuels program, port officials are making up the cost difference.
