Modeling Tip

Reviewing AERMOD Warnings & Errors with a Text Editor

The AERMOD model produces a series of messages which document fatal errors, warnings, and other information messages about a model run. A modeler who knows how to read and interpret the messages can quickly diagnose problems or analyze results.

The image below shows the message summary from an AERMOD Output File.

Messages are grouped into five categories, and the format is the same regardless of the category.

Pathway ID
The input file section where the error/warning occurred. Options include: Control (CO), Source (SO), Receptor (RE), Meteorology (ME), or Output (OU).

Message Code
This consists of a category identifier (E for fatal errors, W for warnings, I for information messages) and a number.

Line Number
The line number in the input file containing the problematic parameter.

NOTE: You can view line numbers in the Windows text editor, Notepad. Disable Word Wrap (from the Format menu) and enabling the Status Bar (in the View menu).

Detailed Message
The first six characters are the subroutine from the model code which tells the model to print the message.

These may include a keyword or parameter which caused the error (e.g., source ID, group ID, etc.)

In AERMOD View, if you select the Output | AERMOD Output File menu option, the AERMOD output file (*.ADO), will be opened in the default text editor on your computer. Scroll to the very bottom of the file to see the messages and use the parameters to identify the meaning of the error or warning.

Submit Your Modeling Tip Today!

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.

Canada Takes Action to Improve Fuel Efficiency and Reduce Greenhouse Gas Emissions from Heavy-Duty Vehicles

DOHA, Qatar - December 4, 2012 - The Government of Canada has initiated proposed regulations that will improve fuel efficiency and help reduce greenhouse gas (GHG) emissions from 2018 model year heavy-duty vehicles by up to 23% from those sold in 2010.

“This Government is committed to improving fuel efficiency and reducing GHG emissions from new on-road heavy-duty vehicles, and from the transportation sector in general,” said Canada’s Environment Minister, the Honourable Peter Kent. “At today’s gas prices, a truck operator driving a model year 2018 vehicle would save up to $9,600 per year in fuel compared to driving a 2010 model year vehicle.”

Declining Air Pollution Levels Continue to Improve Life Expectancy in U.S.

Boston, MA - December 3, 2012 - A new study led by researchers at Harvard School of Public Health (HSPH) has found an association between reductions in fine particulate matter and improved life expectancy in 545 counties in the U.S. from 2000 to 2007. It is the largest study to date to find beneficial effects to public health of continuing to reduce air pollution levels in the U.S.

The study appears in the December 3, 2012 online edition of the journal Epidemiology.

CO2 Output Hits Record High

December 3, 2012 - For 2012, according to new projections by the Global Carbon Project, there is likely to be a 2.6 percent rise in global CO2 emissions from the burning of fossil fuels compared to the year before. That puts emissions of the gas at 58 percent higher than 1990 levels.

In 2011, China was the biggest producer of CO2, accounting for 28 percent of global emissions, researchers report in the journals Nature Climate Change and Earth System Science Data Discussions. The United States followed with 16 percent, the European Union with 11 percent and India with seven percent.

Administration Says No to EU Carbon Tax on Airline Flights to Europe

November 28, 2012 - President Barack Obama signed a bill on Tuesday shielding US airlines from paying for the carbon their planes flying into and out of Europe emit, despite a recent move by Europe to suspend its proposed measure for one year.

The carbon fee bill was the first piece of legislation debated on the House floor after Congress returned from recess on November 13, and had been cleared by the Senate in September in a rare unanimous vote.

EPA Proposes to Update the Mercury and Air Toxics Standards for New Power Plants

November 16, 2012 - The Environmental Protection Agency (EPA) proposed to update emission limits for new power plants under the Mercury and Air Toxics Standards (MATS). The updates would only apply to future power plants; would not change the types of state-of-the-art pollution controls that they are expected to install; and would not significantly change costs or public health benefits of the rule. The public will have the opportunity to comment for 30 days after publication in the Federal Register and at a public hearing in Washington DC if one is requested.
