Lakes Environmental Releases AUSTAL View™ Version 6.3

Lakes Environmental is pleased to announce the release of AUSTAL View Version 6.3 on February 5, 2010. AUSTAL View is the most popular graphical user interface for the world’s most powerful Lagrangian Particle Tracking Air Dispersion Model. This model was developed by the German Federal Environmental Agency and is designed to perform advanced odor modeling and protect the general public and neighborhoods against the potentially harmful effects of air pollution.

With this latest version of AUSTAL View come several new pwerful features including:

  • Now Microsoft® Vista and Windows 7 Compatible

  • A new Wind Rose tool is now available under the Annotation Toolbar for projects with a wind field library

  • New!  User-Defined Building Colors and Shade Styles

For a complete list of the improvements and new features now available in AUSTAL View Version 6.3,please see our latest release notes and watch our new video!

If you are currently in maintenance for AUSTAL View and did not receive an email regarding this update, please contact us at

Product Spotlight - CALPUFF Courses

The Lakes Environmental CALPUFF course is intended for air quality professionals who require practical knowledge of advanced puff-based air dispersion modeling approaches and techniques. This course builds upon essential ADM concepts with a focus on how advanced modeling techniques can be used to produce accurate results at small and large scales or in regions of immense complexity.

As with our popular AERMOD course, this course not only emphasizes the importance of CALPUFF’s theoretical application, but also its practical hands-on functionality.

At the end of the course the attendee will be able to use the appropriate model necessary for a variety of regulatory applications, efficiently using the model at-hand. Students will work on case studies using Lakes Environmental’s CALPUFF View software throughout the course giving "real world" applicability to atmospheric dispersion theory.

Each student will leave the course will a course CD including FREE downloads for Screen View, WRPLOT View, and Percent View.  Also included are course files for case studies as well as links to key modeling resources.

CALPUFF Course attendees are eligible to receive a 10% discount on the purchase of our popular CALPUFF View software

Modeling Tip

Near Structures in BPIP

BPIP, the Building Profile Input Program, is the building downwash processor for AERMOD and other models. When two buildings are processed in BPIP that are sufficiently close, they may be joined together for the purposes of calculating the building wake. It is important to understand how this can happen, as it can affect modeling results.

Buildings closer than L
If two buildings are separated by less than the greater of the two buildings L values, then the buildings will be joined together using a Gap Filling Structure (GFS).  L is defined as the lesser of the building height, and the projected building width (cross sectional width of the building from the current wind direction).

The Gap Filling Structure
The GFS is a structure with height equal to the shorter of the two buildings and connecting the buildings in one or both of the following ways:

  1. Corner to corner
  2. Corner to perpendicular side

Each of these connections must be less than the greater of the two buildings L values.

The images below illustrate some of the possible GFS configurations.  Buildings closer than L are combined by the blue lines, and by the red lines if they are also less than L.

For further details, please refer to the BPIP User’s Guide.

EPA Strengthens Air Quality Standard For Nitrogen Dioxide

WASHINGTON - The U.S. Environmental Protection Agency today announced a new national air quality standard for nitrogen dioxide (NO2). This new one-hour standard will protect millions of Americans from peak short-term exposures, which primarily occur near major roads. Short-term exposures to NO2 have been linked to impaired lung function and increased respiratory infections, especially in people with asthma.

“This new one-hour standard is designed to protect the air we breathe and reduce health threats for millions of Americans. For the first time ever, we are working to prevent short-term exposures in high risk NO2 zones like urban communities and areas near roadways,” said EPA Administrator Lisa P. Jackson. “Improving air quality is a top priority for this EPA. We’re moving into the clean, sustainable economy of the 21st century, defined by expanded innovation, stronger pollution standards and healthier communities.”

Please read the U.S. EPA’s fact sheet for more information regarding this new standard.

Canada Lists Emissions Target Under The Copenhagen Accord

CALGARY, ALTA. (Feb. 1, 2010) - Canada's Environment Minister, the Honourable Jim Prentice, announced on Saturday, January 30, 2010, the submission of Canada’s 2020 emissions reduction target under the Copenhagen Accord. Canada’s target, a 17 per cent reduction from 2005 levels, is completely aligned with the U.S. target, and is subject to adjustment to remain consistent. Canada’s target is contingent on all major emitters associating with the Accord.

“This Government will act on the Copenhagen Accord because it is consistent with Canada’s stated position on climate change and because it moves us closer to our ultimate goal of becoming a clean energy superpower,” said Minister Prentice in a speech today in Calgary. “We took our first step down that road on Sunday, January 31, 2010.”

Climate Change: European Union Notifies EU Emission Reduction Targets Following Copenhagen Accord

The European Union has today formalised its support for the Copenhagen Accord on climate change and presented its commitments for emission reduction targets. In a joint letter with the Spanish Presidency of the Council, the European Commission has formally notified the EU's willingness to be associated with the Accord and submitted for information the EU's established greenhouse gas emissions reduction targets for 2020. These consist of a unilateral commitment to reduce the EU's overall emissions by 20% of 1990 levels and a conditional offer to increase this cut to 30% provided that other major emitters agree to take on their fair share of a global reduction effort. Under the Accord, notifications are to be submitted by 31 January 2010.

Commission President José Manuel Barroso said: " The EU is determined to move ahead rapidly with implementing the Copenhagen Accord in order to make progress towards the agreement that we need to hold global warming below 2°C The Accord provides a basis on which to build this future agreement and I therefore urge all countries to associate themselves with it and notify ambitious emission targets or actions for inclusion as we are doing."

NSR Settlement Means BACT For Big Industry

The EPA's compliance arm filed two major New Source Review (NSR) settlements on Thursday, Jan. 21, 2010, that will force 28 plants across the country to update their air pollution control systems to current best-available control technology (BACT).

The settlements cover 15 U.S. plants owned by Saint-Gobain Containers Inc., Muncie, Ind., the nation's second largest container glass manufacturer, and all 13 U.S. plants owned by the Lafarge Co., Herndon, Va., and two subsidiaries, the nation's second largest manufacturer of Portland cement. These settlements are the first system-wide settlements for these sectors under the Clean Air Act and require pollution control upgrades, acceptance of enforceable emission limits and payment of civil penalties.
