Order AERMOD-Ready Meteorological Station Data in the United States

Most modelers are aware that Lakes Environmental sells modeled MM5 meteorological data for any location worldwide for use in the CALPUFF and AERMOD air dispersion models. This data is very useful for a variety of reasons including:

  • Lack of representative observations (station data) in the modeling domain
  • Unreliable records of meteorological variables
  • Out of date station data

The United States has a very dense network of meteorological stations, and data from these stations is often used to generate meteorological data for AERMOD projects. However, obtaining and processing this data can be time-consuming.

Now, you can order from Lakes Environmental AERMOD-ready meteorological station data in the United States. Rest easy while our team of experts prepares your order using preferred station met data formats:

  • Surface Station Data: TD-3505 hourly surface data from the U.S. National Climatic Data Center (NCDC)
  • 1-Minute Station Data: TD-6405 1-minute ASOS wind data (where applicable)
  • Upper Air Station Data: NOAA FSL radiosonde data
  • Land Use Data: NLCD 1992 GeoTIFF

You won’t have to do any work – orders cover full AERMET processing including AERSURFACE and AERMINUTE (where applicable), and you’ll receive the AERMOD-Ready met files as follows:

  • Surface met data file (*.SFC)
  • Profile met data file (*.PFL)

Modeling Tip

Modeling Haul Roads with Line Sources using AERMOD View

Estimating air quality impacts from haul roads has presented many challenges to air dispersion modelers over the years. From the lack of a true line source to high degrees of variability in emissions estimates, consistent guidance was minimal and confusion was high. Previous releases of AERMOD View™ sought to reduce some of that confusion by adding tools for modelers such as the Line Volume source. While the AERMOD and ISC models do not contain true line sources, the Line Volume source allowed modelers to easily create a series of volume sources along a path. This source type made it quick and easy to add large sets of volume sources thus reducing time and effort.

On March 2, 2012, the U.S. Environmental Protection Agency Air Quality Modeling Group released a report from the Haul Road Workgroup which recommended an approach for haul road modeling. The Haul Road Workgroup Final Report outlined the advantages and disadvantages to a variety of source characterizations, and it provided details on model sensitivity analyses performed by the Workgroup.

The final recommendations from this report were analyzed by our product specialists and developers to enhance the existing line source tool in AERMOD View. The result was a layout change for the Line Source dialog and the addition of the Haul Road Source Calculator. These changes will help modelers tackle haul road modeling challenges faster than ever before!

AERMOD View Line Source Enhancements

The updated line source window gives more flexibility and adds several new features:

  1. Users can now enter a Source ID Prefix (up to 4 characters long) for the volume sources generated along the line. The prefix makes it easier to identify sources when analyzing output or grouping sources.

  2. The window now automatically calculates the Total Length of the line’s path.

  3. The Line Volume source now allows users to select from Separated or Adjacent configuration.

  4. A new Actions menu allows users to Import or Export line source nodes to a comma-separated file (*.csv). This makes it easier than ever to transfer line sources from one project to another. The same menu allows users to manually assign release heights to each node of the line.

AERMOD View Haul Road Source Calculator

AERMOD View Version 7.6.1 also includes the brand-new calculator for modeling haul roads.

The Haul Road Calculator incorporates all recommendations from the Haul Road Workgroup final report. The user only needs to provide a few simple input values:

  • Vehicle height
  • Plume height factor (default of 1.7 per the Haul Road Workgroup report)
  • Lane type (single lane or two lanes)
  • Road width
  • Emission rate

The calculator uses the Haul Road Workgroup final report recommendations to apply the appropriate source inputs to each source along the line.

EPA Takes Next Step to Implement 2008 Ozone Standards

Washington- May 1, 2012 - Working closely with states and tribes, the U.S. Environmental Protection Agency (EPA) is identifying areas that meet or do not meet the 2008 air quality standards for ground-level ozone, known as smog. The agency’s approach to implementing these standards will improve air quality, protect public health, increase certainty for states and tribes, maximize flexibilities and minimize the burden on state, tribal and local governments. Breathing air containing high levels of smog can reduce lung function and increase respiratory symptoms, aggravating asthma or other respiratory conditions. Ozone exposure may also contribute to premature death, especially in people with heart and lung disease.

EPA Issues Updated, Achievable Air Pollution Standards for Oil and Natural Gas

WASHINGTON- April 18, 2012 - In response to a court deadline, the U.S. Environmental Protection Agency (EPA) has finalized standards to reduce harmful air pollution associated with oil and natural gas production. The updated standards, required by the Clean Air Act, were informed by the important feedback from a range of stakeholders including the public, public health groups, states and industry. As a result, the final standards reduce implementation costs while also ensuring they are achievable and can be met by relying on proven, cost-effective technologies as well as processes already in use at approximately half of the fractured natural gas wells in the United States. These technologies will not only reduce 95 percent of the harmful emissions from these wells that contribute to smog and lead to health impacts, they will also enable companies to collect additional natural gas that can be sold. Natural gas is a key component of the nation’s clean energy future and the standards released today make sure that we can continue to expand production of this important domestic resource while reducing impacts to public health, and most importantly builds on steps already being taken by industry leaders.

Ireland EPA Greenhouse Gas Emissions Projections 2011-2020

April 16, 2012 - The EPA today published greenhouse gas emissions projections for the period 2011 to 2020. The figures show the projected trends for greenhouse gases and give a picture of Ireland’s ability to meet EU and international targets with respect to greenhouse gas emissions. The projections will be submitted to the EU as required. Today’s projections update the previous set of national emission projections which were published in April 2011 by the EPA. Two scenarios are developed – one based on policies and measures already in existence or being implemented, and the other on existing measures plus all planned policies and measures that are currently known.

Canada's Greenhouse Gas Emissions Remain Steady While the Economy Grows

April 11, 2012 - “We are seeing good progress in our sector-by-sector approach to reduce our greenhouse gas emissions by 17 percent below 2005 levels by 2020,” said Parliamentary Secretary Gourde. “Emissions have declined in almost all sectors since 2005.”

The Government of Canada simultaneously released the National Inventory Report, the Greenhouse Gas Reporting Program facility-level data and related overview report, and the greenhouse gas indicators of the Canadian Environmental Sustainability Indicators program. These three reports were released together to facilitate greater consistency and to provide Canadians with a coherent picture of emission levels across the country.
