Modeling Tip

Using Flagpole Receptors in AERMOD

Air dispersion models are only capable of calculating concentration at specific locations. These locations are called receptors. In the USEPA’s AERMOD air dispersion model, concentration calculations at each receptor are done at the ground level as opposed to some height above ground. Output from the AERMOD model is often referred to as GLCs for Ground Level Concentrations.

The model does have the capability of measuring concentration at some height above ground, however, through the use of Flagpole Receptor Heights. One example of using a flagpole receptor height is to calculate concentration at an average breathing height (e.g., 1.5 meters).

Follow the steps below on how to add flagpole heights to receptors in AERMOD View:

Step 1: Open the Receptor Pathway options

Step 2: In the Receptor Summary, select Yes for the Flagpole Receptors option. You can also specify a Default Height above ground for all receptors. The Default Height value is used on every receptor where a unique height is not specified.

Step 3: Select the receptor type (e.g., Uniform Cartesian, Discrete Cartesian, etc.) and apply a height.

Step 4:To add a flagpole height to a specific discrete receptor, enter the desired height in the Flagpole Heights [m] (Optional) column of the Discrete Cartesian Receptor options.

Step 5:To add a flagpole height to a receptor within a gridded network, select the grid and click the button. Fill in the desired heights in the grid window. Entire rows can be selected using the Mark icon ().

India Measures Air Quality in World's Most Polluted Capital

April 6, 2015 India's prime minister suggested Monday the country's "age-old traditions" could be used to ease its choking smog, as he launched a new air quality index for the world's most polluted capital.

Narendra Modi proposed making every Sunday "bicycle day" and switching off street lights during a full moon, amid growing public concern over the impact of air pollution on the health of India's 1.2 billion people.

"There can be green solutions in our age-old traditions," he said in a speech at a conference of environmental policymakers in the capital New Delhi.

Climate Summit of the Americas

April 2, 2015 Ontario is hosting a Climate Summit of the Americas, ahead of the 2015 Pan Am and Parapan American Games from July 7 – 9, 2015.

The Summit will bring together Pan-American jurisdictions, as well as environmental groups and industry, to work towards common approaches to reducing greenhouse gas emissions through broader adoption of carbon pricing mechanisms, and highlight opportunities for investing in a global low-carbon economy.

EPA Report: Automakers Surpassing Light-Duty Greenhouse Gas Standards

March 26, 2015 - WASHINGTON - For the second consecutive model year, the automotive industry outperformed the national greenhouse gas (GHG) emissions standards by a wide margin. Overall industry compliance in model year 2013 was 12 grams/mile – or 1.4 miles per gallon – better than required by the 2013 standard.

These were among the top findings released today in the Environmental Protection Agency’s (EPA’s) second annual “Greenhouse Gas Emissions Standards for Light Duty Vehicles: Manufacturer’s Performance Report." The report presents detailed information about how individual firms are complying with GHG emissions standards for cars and light trucks.

Top U.S. Court Questions EPA Emissions Rule for Power Plants

March 25, 2015 - U.S. Supreme Court justices signaled they are divided over Obama administration rules that would cut emissions from 460 coal-fired power plants in an effort to curb birth defects, heart disease and premature deaths.

During arguments Wednesday, justices questioned Environmental Protection Agency controls on mercury and acid gases from the plants owned by Southern Co., American Electric Power Co. and other utilities. Lawyers for power companies and some states said the agency didn’t adequately consider costs before imposing rules estimated to cost $9.6 billion a year.
