Lakes Environmental Offering CALPUFF Courses in the United States

Lakes Environmental is offering CALPUFF Courses in the United States. Last week, April 21-23, Dr. Jesse The', President of Lakes Environmental, was in Dallas, Texas, teaching a 2-day AERMOD course followed by a 3-day CALPUFF course.

Lakes Environmental's AERMOD and CALPUFF courses include a combination of theory and hands-on case studies using Lakes Environmental's advanced graphical user interfaces: AERMOD View and CALPUFF View.

During the 3-day CALPUFF Course in Dallas, students were able to start and finish 9 case studies which involved the geophysical pre-processing, meteorological pre-processing, and CALMET, CALPUFF, and CALPOST options. Here is a list of the case studies used:

  1. Case 1: Class I Area using FLAG2000 options

  2. Case 2: CALMET and CALPUFF modeling using prognostic met data (MM5)

  3. Case 3: Modeling using a multi-tier grid and building downwash

  4. Case 4: Coastal area modeling with Obs and TIBL

  5. Case 5: Complex terrain modeling using MM5 4-km resolution

  6. Case 6: Analyzing several TERRAD values for CALMET wind field

  7. Case 7: Do-It-Yourself case study

  8. Case 8: Odor modeling using area sources

  9. Case 9: Breton Class I Area visibility analysis including PM speciation and FLAG2008 options using the MMS and VISTAS datasets.

The above list of case studies shows that using CALPUFF View results in a significant savings of time and resources. Everything in CALPUFF View is automated. Terrain, land use, meteorological files, and class I receptors are automatically downloaded for your modeling area.

Lakes Environmental is currently selecting the next location in the US for a CALPUFF course. If you are interested in attending a CALPUFF course near you, please contact us by e-mail at

Modeling Tip

Calculating the New U.S. EPA 1-Hour Air Quality Standard for NO2

The U.S. EPA has implemented a new 1-hour standard for Nitrogen Dioxide (NO2) effective April 12th, 2010. This standard is 100 ppb based on the 3-year average of the 98th percentile of the annual distribution of daily maximum 1-hour concentrations.

This new standard cannot be calculated directly by the U.S. EPA AERMOD model and therefore the modeler needs to post-process the POSTFILE created by AERMOD in order to calculate this standard. In order to overcome this, Lakes Environmental implemented this post-processing within AERMOD View Version 6.5.

How the New NO2 Standard is Calculated in AERMOD View

Lakes Environmental's AERMOD View version 6.5 has an integrated post-processor that can perform the necessary calculations and present the results in a standard plot file format.


The user simply needs to select the option in the Output Pathway and specify the desired Source Group and file name. Once AERMOD is run, the NO2 results will be presented with the other results in the Plots tab.

AERMOD View NO2 Tool

New NO2 Standard Calculation Methodology

If you do not have Lakes Environmental's AERMOD View Version 6.5, you can calculatethe NO2 Standard in the following way:

  1. Generate the 1-hour POSTFILE in AERMOD

  2. Determine the highest 1-hour concentration for each day at each receptor

  3. Of these daily maximums, determine the 8th highest (98th percentile) at each receptor for each year seperately

  4. Average the values calculated in Step 3 across all of the modelled years, for each receptor individually

  5. The highest of these values across all receptors should be compared against the 100 ppb limit

A complete description of the NO2 standard methodology can be found in the official U.S. EPA Notification.

DOT, EPA Set Agrressive National Standards for Fuel Economy and First Ever Greenhouse Gas Emission Levels for Passenger Cars and Light Trucks

WASHINGTON (April 1, 2010) - Responding to one of the first major directives of the Obama Administration, the U.S. Department of Transportation (DOT) and the U.S. Environmental Protection Agency (EPA) today jointly established historic new federal rules that set the first-ever national greenhouse gas emissions standards and will significantly increase the fuel economy of all new passenger cars and light trucks sold in the United States. The rules could potentially save the average buyer of a 2016 model year car $3,000 over the life of the vehicle and, nationally, will conserve about 1.8 billion barrels of oil and reduce nearly a billion tons of greenhouse gas emissions over the lives of the vehicles covered.

Canada and the United States Announce Common Standards for Regulating GHG Emissions from New Vehicles

OTTAWA (April 1, 2010) - The Government of Canada today released tough new proposed regulations to reduce greenhouse gas emissions from new vehicles which would harmonize with the mandatory national standards of the United States beginning with the 2011 model year. Today's release of the proposed Passenger Automobile and Light Truck Greenhouse Gas Emission Regulations is the next step in the process that was announced by Environment Minister Jim Prentice in April 2009.

EU Emissions Data Shows 11 Percent Drop in 2009

(April 1, 2010) - Analysis of the data for 2009 from the EU Emissions Trading Scheme (ETS) suggests that EU emissions fell by 11% last year compared with 2008, in line with expectations and prompting a small burst of buying as speculators, who has sold EU allowances (EUAs) in betting on a bigger drop, moved to cover short positions.

Although incomplete - with an estimated 10% of data to come - market analysts agree that the final emissions number is likely to come in around 11% lower in 2009, leaving the EU ETS with a surplus of EUAs. Earlier this week, a survey of analysts by sister publication Carbon Finance found that estimates pointed to a 10% fall.

EPA Formally Announces Phase-in of Clean Air Act Permitting for Greenhouse Gases/Agency Reiterates No Stationary Source Requirements Until 2011

WASHINGTON (March 29, 2010) - Under a final decision issued today by the U.S. Environmental Protection Agency (EPA) no stationary sources will be required to get Clean Air Act permits that cover greenhouse gases (GHGs) before January 2011. EPA has pledged to take sensible steps to address the billions of tons of greenhouse gas pollution that threatens Americans' health and welfare, and is providing time for large industrial facilities and state governments to put in place cos-effective, innovative technologies to control and reduce carbon pollution. Today's announcement is the first step in EPA's phased in approach to addressing GHG emissions laid out by Administrator Lisa P. Jackson earlier this month.
