Modeling Tip
Working with External Source Files in CALPUFF View
When an air dispersion modeling project requires emission variations that do not follow a repeating schedule, it can be a challenge to input the data to the model. Both AERMOD and CALPUFF come equipped with variable emissions options, but the options for temporally-varying emissions are fixed to repeating schedules (e.g., same hours every day or season, whole months, etc.).
What happens when emissions change from one hour to the next? The CALPUFF modeling system allows modelers to input specially-formatted external source emission files, and CALPUFF View has a number of visualization options for these files.
File specifications for CALPUFF external source files can be found in the appropriate user guide for the CALPUFF modeling system being employed (i.e., EPA-Approved, Version 6 / 7).
In CALPUFF View, go to the CALPUFF | External Source Files menu option.
The External Source Files window will appear. Supported source types vary by model version as shown below.
EPA-Approved / Version 6 (top) and Version 7 (bottom) modeling system external source types
Click the Add File button to add the source-specific file to the project. The buttons on the right side of the window provide additional tools for analyzing this data:
|
Window buttons for Point (left) and other (right) source types
Emissions variation graph for point sources
Once the files have been added, the external sources will be depicted using different colors in CALPUFF View’s main display. These colors can be customized using the Graphical Options Color Mapping settings.

EPA to Delay Enforcing Stricter Ozone Rules
June 8, 2017 - The Environmental Protection Agency will delay enforcing compliance with new ground-level ozone standards by one year.
The EPA, under President Barack Obama's administration, issued new ground-level ozone standards of 70 parts of ozone per billion parts of air in the fall of 2015, stricter than the previous standard of 75.
At the time, all of Arkansas was meeting both the standard of 75 and the new standard of 70, officials said, although Crittenden County had not been officially designated as in compliance. It was designated as in compliance in 2016, and the rest of Arkansas remains in compliance with the standard of 75, with average ozone readings below 70.
Trump's EPA Hit with Lawsuit Over Suspension of Oil- and Gas-Drilling Rules
June 5, 2017 - A group of conservation organizations sued the Environmental Protection Agency on Monday, saying the agency unlawfully suspended Obama-era rules to cut methane pollution.
The lawsuit is another sign that environmentalists intend to use the courts to block President Donald Trump's effort to roll back energy regulations and climate change initiatives pushed by his predecessor.
Air Pollution Fears See Demand for Diesel Cars Fall by Fifth
June 5, 2017 - Demand for new diesel cars plummeted by a fifth last month amid rising concerns over air pollution.
Approximately 81,500 new diesel cars were registered in the UK in May, down 20% on the same month last year, according to the Society of Motor Manufacturers and Traders. This represented a fall in market share from 50% to 43.7%.
The fall comes amid a flurry of negative publicity around the impact of diesel-fuelled vehicles on the environment and people’s health
Pizza Oven Affected Montreal Air Quality Readings, Report Says
June 1, 2017 - Montrealers can breathe a sigh of relief to learn their air is less polluted than previously thought — due in part to a pizza oven that was skewing air quality readings.
An environmental report released this week shows the number of days with poor air quality plunged last year, right after the city closed a sampling station that was next to a pizzeria with a wood-burning oven.
Choked by Traffic, Bangkok Revs Up to Beat Air Pollution
May 18, 2017 - There are two pictures Thai air pollution expert Supat Wangwongwatana likes to show whenever he talks about Bangkok's transition, in a little over a decade, from a city blanketed in smog to one boasting clear blue skies.
The first, taken in the mid-1990s, shows the skyline of downtown Bangkok. Most buildings are in silhouette, shrouded in a thick layer of haze. The Baiyoke Tower, back then the city's tallest building, was still under construction.
