Modeling Tip

Change the Default Text Editor

Most air dispersion models produce simple text input and output files. To display these files, Lakes Environmental’s products call a default text editor. Different text editors provide different functionality. To take advantage of these features, you can change the default text editor called by our software.

  1. Access Preferences from the File menu.

  2. Select System Editor from the Settings list

  3. Choose from WordPad, Notepad, or User-Specified Editor

One benefit to using Notepad is the ability to identify line numbers. With Word Wrap turned off (go to Notepad’s Format menu and deselect Word Wrap), you can enable the Status Bar under the View menu. The Status Bar tracks the cursor and tells you the Line and Column number of the cursor’s present position.

This is useful for identifying the location of errors within model files. For example, AERMOD always prints a line number in warning and error messages. The warning message below references line 38 as the location of a potential out-of-range source parameter (VS for exit velocity).

If we open the input file and search for line 38, we find a point source with an exit velocity > 50 m/s.

You can also choose a User-Specified Editor from the Preferences menu. The example below uses the open source program Notepad++ as the new default editor before opening a CALMET input file from CALPUFF View.

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.

EPA Issues Annual Report on Chemicals Released to Land, Air and Water in New York Data Finds Reduction from Previous Year

February 4, 2014 - (New York, N.Y.) The annual U.S. Environmental Protection Agency report on the amount of toxic chemicals released to the land, air and water by industrial facilities in New York State in 2012 showed a slight decrease over the previous year’s data. The Toxics Release Inventory report issued today by the EPA covers 633 New York facilities that are required to report their releases to the agency. Total releases to land, air and water reported in 2012 was 13.8 million pounds, which was a 6,000 pound reduction from 2011.

“The Toxics Release Inventory allows the public and policymakers to better understand the pollutants released into our air, water and land each year," said EPA Regional Administrator Judith A. Enck. "This powerful tool helps people better understand pollution problems in their communities and take action to protect their health and the environment."

Environmental Health Risks of Alberta Oil Sands Likely Underestimated

February 4, 2014 - VICTORIA - A new study suggests the environmental health risks of oilsands operations in Alberta’s Athabasca region have probably been underestimated.

Researchers say emissions of potentially hazardous air pollution that were used in environmental reviews done before approving some projects did not include evaporation from tailings ponds or other sources, such as dust from mining sites.

European Commission Recommends Minimum Principles for Shale Gas

January 22, 2014 - Today the European Commission adopted a Recommendation aiming to ensure that proper environmental and climate safeguards are in place for "fracking" – the high-volume hydraulic fracturing technique used notably in shale gas operations. The Recommendation should help all Member States wishing to use this practice address health and environmental risks and improve transparency for citizens. It also lays the ground for a level playing field for industry and establishes a clearer framework for investors.

The Recommendation is accompanied by a Communication that considers the opportunities and challenges of using "fracking", to extract hydrocarbons. Both documents are part of a wider initiative by the Commission to put in place an integrated climate and energy policy framework for the period up to 2030.

Economic Benefits of Reducing Nitrogen Pollution

January 14, 2014 -Falling levels of nitrogen in the atmosphere across Europe may be much more economically beneficial than previously believed, according to a recent study.

Indeed, scientists think the UK alone benefits by around £65 million a year. Levels of atmospheric nitrogen have fallen by around a quarter in Europe since 1990, mostly because of tighter rules on emissions from engines and industry. Scientists are still working to understand the consequences.

EPA's New Greenhouse Gas Emissions Standards Now Open for Public Comment

January 10, 2014 – Politically contentious as ever, climate change is back in the headlines, as a brutal, deep and prolonged southward shift in the polar vortex has put much of the continental U.S. in a deep freeze. In stark contrast, people living in the Southern Hemisphere — in Australia, Argentina and Brazil, for example — are trying to cope with heat waves, the threat of drought and power outages in major cities. While many are scrambling with the immediacy of such problems, the U.S. Environmental Protection Agency (EPA) is moving forward with longer term, structural fixes to address climate change conceived by the Obama Administration. On Jan. 8, the EPA issued proposed new performance standards that would put an upper limit, or cap, on carbon and greenhouse gas (GHG) emissions from new, stationary power plants under Section 111 of the Clean Air Act.

Study Results in Improved Reporting of GHG Emissions

December 20, 2013 - VICTORIA - A joint field study between the B.C. government and the Canadian Association of Petroleum Producers is resulting in a more accurate accounting of greenhouse gas emissions from the oil and gas sector. This study is part of a larger update of the measurement methods on a series of emissions sources for B.C.'s large industrial reporting requirement.

The study was prompted by concerns about the reliability of GHG emissions data provided by the manufacturers of pneumatic devices, which are common instruments at well sites and along pipelines that use pressurized gas to control processes.
