Lakes Environmental Wins 2013 ESRI Award

Lakes Environmental is pleased to announce that our paper, "Computing Non-Crossing Smooth Contours on Triangulated Meshes" was the first place recipient of the 2013 ESRI Award for Best Scientific Paper in Geographic Information Systems. This paper was authored by Dr. Yurai Núñez-Rodríguez, Dr. Igor Raskin, Dr. Jesse Thé, and Mr. Michael A. Johnson.

The award winning article resolved an electronic mapping problem that had been investigated by international research centers for more than two decades.

The 2013 ESRI Award places us as one of the top GIS scientists worldwide and is a definite recognition of the high level of research conducted at Lakes Environmental.


“Guideline on Air Quality Models” Conference Wrap-Up

Lakes Environmental was a proud sponsor of the recent Air & Waste Management Specialty Conference“Guideline on Air Quality Models: The Path Forward” held by the A&WMA Technical Coordinate Committee for Meteorology and Air Quality Modeling Issues (AB-3). The conference was held March 19 to 21, 2013 at the Sheraton Hotel in Raleigh, North Carolina.

Nearly 60 presentations were given with topics covering AERMOD evaluation and validation, CALPUFF topics, background concentrations, secondary pollutant formation and modeling, meteorological data issues, discussion of the guideline, and other modeling topics. The conference also featured an exclusive town hall meeting with staff from the U.S. Environmental Protection Agency and Federal Land Management offices.


Our own Michael Hammer presented his paper, “Prognostic Data in AERMET: A Case Study of MMIF versus NWS Data”, which analyzed the beta interface for preparing prognostic meteorological model data for use in the AERMOD model.

Modeling Tip

Export Threshold-Exceeding Receptors in AERMOD View™

Complex air dispersion modeling projects may require large amounts of time to process. One way to reduce model runtimes is to reduce the number of receptors. A method by which some regulatory agencies allow modelers to reduce their receptors is through the use of significant receptors. To identify significant receptors, modelers must first complete a run using a large receptor grid. A concentration threshold is specified and receptors which exceed the threshold are extracted for further processing.

The latest release of AERMOD View™, Version 8.2, includes a brand-new feature which allows modelers to export a list of receptors by their concentration. To export these receptors, follow the steps below.

Step 1: Perform an AERMOD model run. Be sure to include Contour Plot Files in the Output Pathway options for the averaging period and source group combinations of interest.

Step 2: Following the successful completion of the model, go to the Plots Tree Menu and select the plot file you wish to view.

Step 3: Click the Export to CSV button and select the Export Range option. This will open the Export Plot to CSV Options window.

Step 4: Identify the concentration (or deposition flux) range over which receptors will be exported. In the example below, all receptors with a concentration exceeding 188 µg/m³ will be exported to the CSV file.

Step 5: The exported CSV file can be imported to any AERMOD View project as a series of new discrete receptors. Under the Receptor Pathway, select the Discrete Cartesian option and select Import from File from the Actions menu.

Step 6: The Receptor Import Parameters window will appear with the receptor data divided into columns. The data is ordered in an identical manner to the contour plot file.

  • Column 1 contains the X coordinate data
  • Column 2 contains the Y coordinate data
  • Column 3 has the measured concentration at the exported receptor
  • Column 4 contains the elevation
  • Column 5 contains the hill height

Air Pollution-Caused Deaths Total Over One Million Per Year in China

April 5, 2013 - In January, NASA revealed satellite images showing dramatic visuals of air pollution over China. Consequently, a new analysis is reporting that more than 1 million people are dying prematurely every year from air pollution in China alone.

We reported earlier that air pollution, especially around Beijing has greatly been influenced by coal-fired power stations. However, population growth along with increasing development is causing the nation into an air pollution crisis.

"Cars are being added and trucks are being added to the streets in major cities at record numbers. Power plants burn significant amounts of very low-grade coal, and the energy consumption in China is rising dramatically," says Robert O'Keefe of the Health Effects Institute in Boston and presenter of the findings. "This is the highest toll in the world and it really reflects the very high levels of air pollution that exist in China today."

Ontario Almost Totally off Coal Generation

April 2, 2013 - Ontario is on the verge of becoming the first industrial region in North America to eliminate all coal-fired electrical generation. Here’s how Canada's most populous province did it — and what the U.S. and others can learn from it.

By most measures of environmental policy and progress, Ontario, Canada ranks well. Over the last half-century, Canada’s most populous province required cities and industries to treat every gallon of wastewater, dramatically reduced the level of sulfur and other pollutants that caused acid rain, and convinced the big and politically powerful pulp and paper industry to install state-of-the-art emissions control equipment.

EPA Proposes Achievable Cleaner Fuels and Cars Standard

WASHINGTON - March 29, 2013 - Based on extensive input from auto manufacturers, refiners, and states, the U.S. Environmental Protection Agency (EPA) today proposed sensible standards for cars and gasoline that will significantly reduce harmful pollution, prevent thousands of premature deaths and illnesses, while also enabling efficiency improvements in the cars and trucks we drive. These cleaner fuels and cars standards are an important component of the administration’s national program for clean cars and trucks, which also include historic fuel efficiency standards that are saving new vehicle owners at the gas pump today. Once fully in place, the standards will help avoid up to 2,400 premature deaths per year and 23,000 cases of respiratory ailments in children.

Following a proven systems approach that addresses vehicles and fuels as an integrated system, today’s proposal will enable the greatest pollution reductions at the lowest cost. The proposal will slash emissions of a range of harmful pollutants that can cause premature death and respiratory illnesses, including reducing smog-forming volatile organic compounds and nitrogen oxides by 80 percent, establish a 70 percent tighter particulate matter standard, and reduce fuel vapor emissions to near zero. The proposal will also reduce vehicle emissions of toxic air pollutants, such as benzene and 1,3-butadiene, by up to 40 percent.

EPA Updates Mercury and Air Toxics Standards for New Power Plants

WASHINGTON - March 29, 2013 - The U.S. Environmental Protection Agency (EPA) has issued updates to pollution limits for new power plants under the mercury and air toxics standards, based on new information and analysis that became available to the agency after the rule was finalized.

The updates are largely technical in nature and will have no impact on the sensible, achievable and cost-effective standards already set for existing power plants. The public health benefits and costs of the rule remain unchanged. EPA estimates that the standards, which will protect the health of millions of families, especially children, will prevent as many as 11,000 premature deaths and 4,700 heart attacks every year. The standards will also help America’s children grow up healthier-- preventing 130,000 cases of childhood asthma symptoms and about 6,300 fewer cases of acute bronchitis among children each year.
