Modeling Tip

Receptor Elevation Options in AERMOD View™

The AERMOD model can calculate ground-level concentrations in either flat or elevated terrain. AERMAP is used to calculate model object elevations, and its output can be passed to AERMOD in one of two ways:

  1. The model object LOCATION cards written to the AERMAP output files can be copied and pasted into the AERMOD input file, or
  2. The AERMOD input file can point to the AERMAP output files to be read as model input

The second method is more efficient for receptors than sources since external source files must also contain source parameter information. Both of these options have been incorporated into AERMOD View to make modeling easy.

This option is available in the Control Pathway under the Terrain Options heading:

Modelers can choose between Flat, Elevated, or Flat & Elevated terrain (an option which allows you to dictate that some sources should be modeled with flat terrain algorithms while others are modeled with elevated). When modeling with Elevated terrain, AERMOD View displays options for adding receptor elevations to the project.

The default option is to Run AERMOD using AERMAP Receptor Output file (*.ROU). This file is created automatically by AERMOD View’s Terrain Processor and contains the following information for each receptor point:

  • X-coordinate
  • Y-coordinate
  • Elevation
  • Hill Height

The other option will automatically write the elevations calculated by AERMAP to AERMOD View’s Receptor Pathway tables.

The first option helps to reduce errors because the user cannot modify the receptor elevation values. The catch is that any desired changes in the receptors (e.g., moving a receptor, deleting receptors) requires the modeler to rerun AERMAP in order for the changes to be recognized by the model.


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.

EU Proposes to Curb Oversupply of Carbon Credits

July 8, 2013 - Carbon credits are created by emissions controls and by other manufacturing practices and they can be sold to other facilities to offset emissions that cannot be economically reduced. These are attractive when a facility cannot meet a new regulation, and is near the end of its useful life, making it uneconomic to install expensive new emissions controls. Carbon credits can also be held or eliminated to reduce available credits. This results in a loss of potential value to those who created them, but is good for the environment since this reduces total Carbon emissions. The EU is proposing to temporarily curb an oversupply in Carbon credits.

Update: UN Climate Change Talks Start Making Progress

June 15, 2013 - The United Nations climate change body said it has made concrete progress towards a new universal agreement on climate change during its latest round of talks which wrapped up this week in Germany.

"This has been an important meeting because Governments are moving faster now from the stage of exploring options to designing and implementing solutions," said Christiana Figueres, Executive Secretary of the UN Framework Convention on Climate Change (UNFCCC).

China Sets New Rules Aimed at Curbing Air Pollution

June 15 2013 - Hong Kong - China’s cabinet has adopted 10 measures to improve air quality in the latest move aimed at responding to the dense smog that has repeatedly enveloped Beijing and other major Chinese cities in recent years.

Many of the measures had previously been enacted by some cities, or were the subject of national experiments that had not yet received the imprimatur of the cabinet, which is known as the State Council. The measures, adopted Friday, were announced Saturday in state-controlled news media.

Greenhouse Gases: 2011 Emissions Lower Than Previously Estimated

May 29, 2013 - Greenhouse gases fell by 3.3 % in the EU in 2011, leading to the lowest level of emissions in reports going back to 1990. The decrease in 2011 was also the third largest over this period, according to official data compiled by the European Environment Agency (EEA) and reported by the EU to the United Nations Framework Convention on Climate Change (UNFCCC).
