Modeling Tip

How to Change Executables in AERMOD View

In last month’s Modeling Tip, we discussed how to track which versions of the AERMOD and AERMET models were used for a specific project. Here, we look at how you can change the version of AERMOD used by AERMOD View.

Numerous versions of the AERMOD model have been released over the years. As the model is updated, new versions are published by the US EPA to the Support Center for Regulatory Atmospheric Modeling (SCRAM). There are many situations where a modeler may wish to use an older version of the AERMOD executable. For example:

  • Regulators in some countries may still mandate the use of an earlier version of AERMOD.
  • A specific version of AERMOD may be stipulated in the modeling plan and permit application, even though a newer version of the model may have become available since the project started.
  • There are certain situations where a custom recompiled version may be required to support specific non-regulatory options or to implement advanced modeling configurations such as the ability to run in a parallel processing environment.

The newly-released AERMOD View Version 9.3.0 supports the latest US EPA model update (version 16216r) as well as several previous releases including 15181, 14134, and more. To change the version of AERMOD used by the interface, complete the following steps.

  1. Open the File menu and select Preferences.
  2. The various models available in AERMOD View are listed under the EPA Models/Limits section. Select AERMOD.

  3. The default executable is AERMOD.EXE which represents the most recent US EPA executable (currently 16216r). Select the drop-down list to see all available model executables.

  4. Select the version of the model you want to use. Executables named AERMOD_MPI_LAKES_xxxxx.EXE represent the parallelized version of the listed model number. This version is developed by Lakes Environmental and is included free of charge for AERMOD View users who have a computer with multiple processors (see installation instructions for further information).

    Note that the selected version is ‘sticky’. You will continue to run with the selected executable until the next time a change is made.

  5. Users can also select their own recompiled version of AERMOD by selecting the User-Specified radio button. Use the Browse button to search your computer for the desired executable. When modeling with a User-Specified executable, it is the user’s responsibility to verify all the proper model options are selected.

We are currently accepting submissions for the Monthly Modeling Tip section that appears in our newsletters. If you have a modeling tip that may benefit our readers, please send it to us at Your name and the name of your organization will appear below the tip providing you with an opportunity for increased exposure.

Clean Air Act, Other Environmental Regulations Potentially Targeted by New Executive Order

February 2, 2017 - On Monday, President Donald Trump signed an order that will require federal agencies to cut two existing regulations for every new rule and that will set an annual cap on the cost of new regulations with the exceptions of military and national security regulations. For fiscal year 2017, the cap will require that the cost of new regulations be completely offset by the rescinding of existing rules. Starting in 2018, the order directs the White House Office of Management and Budget head to give each agency a budget for increasing or decreasing regulatory costs.

Car Ban Fails to Curb Air Pollution in Mexico City

February 2, 2017 - Banning cars on Saturdays in Mexico City hasn't reduced air pollutants, according to a new study.

Scientists had expected that limiting driving at the weekend would reduce vehicle emissions by 15%.

But this analysis looking at pollution measurements in a city with serious air quality problems, found no discernible effect.

Residents got around the restrictions by car pooling, using taxis and purchasing extra vehicles, researchers say.

Back in 1992, the UN declared Mexico City the world's most polluted city.

MEPs in Bid to Force UK to Meet Environmental Regulations After Brexit

January 31, 2017 - Britain would be forced to abide by key EU environmental regulations by a pan-European court as part of any Brexit deal, according to a leaked document detailing the negotiating red lines being drawn up by the European parliament.

Drafted by MEPs, the paper says the UK should not be allowed to damage the wider European environment after its withdrawal from the EU by unilaterally weakening its commitments to reducing pollution emissions and protecting wildlife.

Climate Change Poses Increasingly Severe Risks for Ecosystems, Human Health and the Economy in Europe

January 25, 2016 - Europe’s regions are facing rising sea levels and more extreme weather, such as more frequent and more intense heatwaves, flooding, droughts and storms due to climate change, according to a European Environment Agency report published today. The report assesses the latest trends and projections on climate change and its impacts across Europe and finds that better and more flexible adaptation strategies, policies and measures will be crucial to lessen these impacts.
