Modeling Tip

Customize AERMOD’s Output Units

The AERMOD model features default units for emission inputs and concentration or deposition outputs. Emissions are presented as grams per second (g/s)*, and concentrations are calculated as micrograms per cubic meter (µg/m3). However, there may come a time when one or both of these default units needs to be changed to better represent project data. This change can be easily made via the Source Pathway options.

Under the Source Pathway, look under Source Options and select the Emission Output Unit heading.

To modify the parameters, select the User Defined radio button. The user can then supply their own values for each of the three fields:

  • Unit Factor: The factor used to convert the emission rate input units to the output units. The default factor of 1000000 is used to get micrograms as output from the input of grams.
  • Emission Unit Label: The label applied to the emission unit. This may be up to 40 characters in length.
  • Concentration Unit Label: The output unit label. This may be up to 40 characters in length.

One time where adjusting the unit labels can help is when the default units produce numeric values that are too large or too small for the model to accurately write. For example, if the emissions for a given source were very small (e.g., 1E-6 g/s), the output concentrations may be too small for the model to write (<1E-5 µg/m3). In this situation, you could input a unit factor of 1 and change the Emission Unit Label to MICROGRAMS/SEC so that the results are not excessively-lowered to the point of not writing them. Making such an adjustment will help produce more detailed contour plots since the numeric data will be more precise and easier to work with.

Submit Your Modeling Tips 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.

New ASHRAE Handbook - HVAC Systems and Equipment Published

July 7, 2016 - ASHRAE has announced revisions to the majority of chapters, including major updates related to thermal storage and district heating and cooling, in its newly published 2016 ASHRAE Handbook – HVAC Systems and Equipment.

The volume discusses various systems and the equipment, components, or assemblies they comprise. It describes features and differences, to help system designers and operators in selecting and using equipment.

“Nearly 90 percent of the chapters have undergone revision since the 2012 volume was published,” said Forrest Yount, volume chair. “That means there is a lot of new material for users to become familiar with. Many chapters have incorporated the results of recent research projects funded by ASHRAE.”

There's More Blue in Beijing Skies These Days

July 1, 2016- You can see the mountains today in Beijing. That's a giveaway that the air's pretty clean. Of the six days that I've been in the city, the mountains north of the city have been visible on three.

Beijing's air quality has always varied a lot from day to day depending on whether and which way the wind was blowing. Still, I was curious: could the famously bad air here actually be getting better?

The answer seems to be yes. There still are terrible days, especially in the winter. But overall, average concentrations of fine particulate matter (PM 2.5) have been trending down since 2013.

Air Pollution Kills 6.5 Million People Every Year, and It Could Get Worse Unless We Act Now

July 1, 2016- Exposure to indoor and outdoor air pollution is linked to the premature deaths of about 6.5 million people every year, according to new International Energy Agency cautionary report this week. That makes it the fourth-largest threat to human health after high blood pressure, dietary risks and smoking.

And the number of deaths attributed to poor air quality is set to only rise in the coming decades, said the Paris-based energy security group — unless swift international action is taken to tackle this crisis.

Air Quality Substandard in all Taiwan Cities, Counties Except Taitung

June 28, 2016 - European countries, which rely heavily on diesel-fueled vehicles, remain far behind the United States in their efforts to reduce harmful air pollution, according to a report to be issued Thursday by the World Health Organization.

Taitung County is the only municipality in Taiwan that meets a new air quality standard, which will be introduced next year, according to a report released Tuesday by the Environmental Protection Administration (EPA).

Based on the annual average of fine particle pollution (PM2.5) over the past three years, all the municipalities except Taitung have been designated as Level-3 control areas, which means they will have to take steps to reduce their levels of PM2.5 pollution, the EPA said.

Louisiana Waiting for Feds' Response to EPA Ozone Regulation Suit

June 20, 2016 - TLouisiana is among a coalition of states awaiting a response from federal attorneys to its opening brief in a lawsuit against the U.S. Environmental Protection Agency's (EPA) new ozone limits.

Louisiana, Wisconsin, Arizona, Kentucky, New Mexico, Arkansas, North Dakota, Oklahoma, Utah and Texas filed the lawsuit in the U.S. Court of Appeals in Washington D.C., arguing that the new ozone standards are unachievable and would require the halting of human activity across large parts of the country. In the opening brief filing, the states stated that this is an abuse of the EPA’s discretion.
