US EPA Releases AERMOD, AERMET, and MAKEMET Models Version 15181

On July 24, 2015, the U.S. EPA posted updates to the AERMOD air dispersion model, and the AERMET/MAKEMET meteorological data preprocessor on the SCRAM website. As mentioned above, these model updates have been incorporated into the AERMOD View, AERMET View, and the AERMOD MPI (parallel version) to address the new model changes.

Some of the major model changes include:

  • New Buoyant Line source type derived from the BLP dispersion model.
  • Added the beta PVMRM2 option for NOx-to-NO2 conversion. This option is an updated version of the existing PVMRM option.
  • Added an additional beta option for handling low wind speeds (LOWWIND3).
  • Annual average POSTFILEs now include results from each individual year in a model run spanning multiple years.
  • And more!

If you are a user of AERMOD View but are no longer in maintenance please contact for pricing to update your software.

US EPA Releases AERSCREEN Model Version 15181

On July 24, 2015, the U.S. EPA posted an update to the AERSCREEN air dispersion model on the SCRAM website. Changes include the incorporation of shoreline fumigation and inversion break-up routines.

Lakes Environmental team is hard at work updating AERSCREEN View with the model updates. Lakes Environmental plans to release the new version of AERSCREEN View in a few weeks. Be on the lookout for an email from us announcing this new release.

Modeling Tip

Create Plume Animations in AERMOD View

The AERMOD air dispersion model is capable of producing many different types of output files. One output file – the Post-Processing File – can produce time series data for each receptor. Lakes Environmental’s brand-new AERMOD View Version 9.0 now includes a special option which uses the Post-Processing File to create hourly time series plume animations.

To use the new feature, the Plume Animation option must be enabled in the Output Pathway window. Separate animations can be made for each source group

After a successful AERMOD model run, the Plume Animation tree menu will appear. Options include animation speed, looping option, source group selection, and more.

To manually jump from one time to the next, use the blue Time Range controls. The green buttons in the Animation Controls allow you to play the plume animation forwards or backwards.

To record and playback a plume animation video:

Step 1: Open the Multimedia menu and select Record Animation

The Multimedia Options dialog will appear and remain on top of all other layers in the software.

Step 2: Select the desired Frame Rate (the number of frames per second that will appear when the animation is played). Higher Frame Rates will play much faster.

Step 3: The Advanced Settings allow you to choose color depth and compression options. Modify if necessary.

Step 4: In the main display, set up the animation controls to the point where you want the recording to begin. You can also modify the Graphical Options to make changes to contour settings and more.

Step 5: When you’re ready to begin, click the Begin Recording button   in the Multimedia Options dialog. You will then need to hit the Play button on the Animation Controls.

When the recording is complete, you can view the AVI file by selecting the Play button from the Multimedia Options dialog or by using the Multimedia | Play Recording menu option.

The Final Clean Power Plan

August 3, 2015- President Obama announced EPA’s historic Clean Power Plan, a first-of-its-kind step to cut the harmful carbon pollution fueling climate change from our nation’s power plants. Climate change threatens our health, our economy, and our way of life with impacts like more intense heat, cold, droughts, floods, fires, and storms. And power plants are our nation’s largest driver of climate change, making up a third of our carbon pollution emissions.

Compared with last year’s proposal, the final Clean Power Plan cuts over 70 million more tons of carbon pollution, making it more ambitious. And based on more than two years of extensive outreach, plus the 4.3 million public comments we received, we made changes to improve the proposal, so that the final Clean Power Plan is more achievable and more affordable, too.

Battle Against Pollution: European Cities to Ban Cars from Roads for One Day

July 23, 2015 - Cities across Europe will ban cars from their roads for one day in September, as part of a campaign to promote more sustainable transport.

While major capital cities across the continent have been bringing in a raft of measures to try and tackle pollution — as recent studies have also begun to lay bare the full effects of its dangers — a scheme to encourage greener transport measures has attracted hundreds to take part in a range of initiatives, including closing roads to cars.

Canada Can't Afford Complacency on Air Pollution: CMAJ Editorial

July 20, 2015 - Canada is being called on to adjust to recently established global guidelines for air pollution.

In an editorial, the Canadian Medical Association Journal advocates following the lead of the World Health Organization, which in May updated the acceptable levels of small particulate matter, nitrogen dioxide and ground-level ozone.

The CMA is particularly concerned about the impact of air pollution on children.

France Estimates the Economic Costs of Air Pollution

July 16, 2015 - The French Senate has called for new efforts to tackle air pollution, arguing it inflates healthcare costs, reduces economic productivity and agricultural yields, and has put Paris in the EU's bad books.

A Committee of Inquiry in the French Senate has described air pollution as an "economic aberration". The committee's proposals to reduce the phenomenon, which costs France over €100 billion every year, include raising the tax on diesel and taxing emissions of the worst polluting substances.

Nearly 9,500 People Die Each Year in London because of Air Pollution – Study

July 15, 2015 - Nearly 9,500 people die early each year in London due to long-term exposure to air pollution, more than twice as many as previously thought, according to new research.

The premature deaths are due to two key pollutants, fine particulates known as PM2.5s and the toxic gas nitrogen dioxide (NO2), according to a study carried out by researchers at King’s College London.

Sulfur Regulations Improving Air Quality in Hong Kong

July 10, 2015 - Air quality levels in Hong Kong have improved in the first half of 2015 compared to the same time last year, a change which has been attributed to the recent implementation of low-sulfur regulations on berthed ocean-going vessels (OGV), according to industry group Clean Air Network.
