Modeling Tip
Debug Files in AERMOD
A feature of the AERMOD model is the ability to generate Debugging Output Files of intermediate calculation results. These files allow modelers to debug model output and better understand the modeled results. The Debugging Output Option is controlled by the Control Pathway using the DEBUGOPT model keyword.
There are several different Debugging Output files a modeler could potentially generate:
- MODEL: This option prints intermediate calculations related to model results for each source and receptor. Dispersion parameters, plume heights, etc. are displayed in this file.
- METEOROLOGY: Gridded profiles of meteorological variables for each hour of data are output here.
- PRIME: Contains plume rise calculations impacted by building downwash for specific point source – wind direction combinations.
- DEPOSITION: Creates two separate output files – one for gas deposition calculations (GDEP.DAT) and one for particle deposition calculations (PDEP.DAT). Includes parameters such as depositional velocity.
- AREA / LINE SOURCE: This is a separate debugging output file for intermediate calculations from area, line, and open pit source types. It was introduced in the 14134 model version.
- NO2: Secondary model keyword is based on the NO2 modeling option selected – PVMRM, OLM, ARM, or ARM2. For PVMRM or OLM, calculations of ozone moles in the atmosphere are presented. ARM or ARM2 files contain ratioing calculations.
In AERMOD View, Debugging Output Files are controlled by the Debug Files option of the Control Pathway window. Place a checkmark in the box of the file type you want to enable. The Save icon can be used to assign a different name to the file.
Files are stored in the project directory by default and can be opened with a text editor (e.g., WordPad, Notepad).
The most important thing to keep in mind about debug files is that they contain an extremely large amount of data. Because intermediate calculations are printed for every source-receptor combination and each hour of meteorological data, these files can grow to hundreds of gigabytes in size if they are not properly controlled.
It is recommended that the Debugging Output files be used for limited amounts of data – single source, single receptor, single hour of met data – in order to limit file sizes and make the data more pertinent.

Articles
EPA Proposes Updates to Reduce Methane, Other Harmful Pollution from New Landfills
July 1, 2014 - WASHINGTON - As part of the President’s Climate Action Plan – Strategy to Reduce Methane Emissions, the U.S. Environmental Protection Agency (EPA) is proposing updates to its air standards for new municipal solid waste (MSW) landfills. These updates would require certain landfills to capture additional landfill gas, which would reduce emissions of methane, a potent greenhouse gas, and help further reduce pollution that harms public health. The agency also is seeking broad public feedback on how and whether to update guidelines for existing landfills.
Non-hazardous waste from homes, business and institutions ends up in municipal solid waste landfills, where it decomposes and breaks down to form landfill gas, which includes carbon dioxide, a number of air toxics and methane. Methane has a global warming potential 25 times that of carbon dioxide.
EPA Proposes Approval of New Climate-Friendly Refrigerants
June 27, 2014 - WASHINGTON -In support of President Obama’s Climate Action Plan, the U.S. Environmental Protection Agency (EPA) is proposing to increase the options for refrigerants in the United States that offer better climate protection without harming the ozone layer. This is the agency’s first action that addresses refrigerants under the Climate Action Plan, which calls on EPA’s Significant New Alternatives Policy (SNAP) Program to identify and approve additional climate-friendly chemicals.
UCLA Students Create Website to Inform on Toxic Emissions
June 17, 2014 – A team of seven UCLA environmental science students has created a website that shows how emissions from local factories are impacting air quality in Los Angeles County. Cal EcoMaps, launched this month, features an interactive map with detailed information about 172 facilities representing the top four emitting industries — petroleum, primary metals, fabricated metals and chemical production.
Lost Industry Brings Job Losses But Better Air Quality
July 3, 2014 - When it comes to air quality in Hamilton, there’s good news and there's bad news. The good news? Hamilton’s air quality has been dramatically improving since the mid-1990s, and continued to improve in the last year. Fewer Hamiltonians are also dying prematurely from bad air quality — 229 deaths in 2003 compared to 186 in 2012. The bad news? Some of that improvement is because the city has lost industry and manufacturing jobs.
EPA Announces Funding for Tribes to Clean Up Diesel Engines
June 6, 2014 - WASHINGTON - The Environmental Protection Agency (EPA) announced today that grant funding is available for tribal applicants to establish clean diesel projects aimed at reducing emissions from older diesel engines. Diesel engines are extremely efficient, but emit air pollutants such as nitrogen oxides (NOX) and particulate matter (PM). These pollutants are linked to serious health problems including asthma, lung and heart disease, other respiratory ailments, and premature death. This is the first time EPA is offering a separate tribal request for proposals for diesel emission reduction program (DERA) funds, and is in response to feedback from tribal communities.
Choosing the Right Path: How Air Travel Affects Climate Change
June 26, 2014 - TIt has been well documented that one negative of air travel — besides the food — is the emission of CO2 from jet engines. But what about contrails?
Dr. Emma Irvine, Professor Keith Shine, and Professor Sir Brian Hoskins, at the Department of Meteorology at the University of Reading have linked contrails to global climate change in a study published in IOP Publishing's journal Environmental Research Letters.
