Distributor Spotlight – Ak-Tel Mühendislik Co., Ankara, Turkey
Ak-Tel Mühendislik Co., based in Ankara, Turkey became a distributor of Lakes Environmental Software in 2010. Since then our relationship with Ak-Tel remains very positive. Ak-Tel represents a wide range of Lakes Environmental’s software including the following air quality disciplines:
- Air Dispersion Modeling
- Compliance Assurance
- Emergency Release
- Emissions Management
- Risk Assessment
As another positive outcome, on April 24, 2018 Ak-Tel promoted our AERMOD View software at an environmental air quality meeting organized by the Chamber of Environmental Engineers. The meeting was well attended and covered a wide variety of AERMOD View features and capabilities as well as common regulatory applications.
We appreciate the continued support of Ak-Tel. Please contact Lakes Environmental for your software and meteorological data needs in Turkey and we will happily refer you to Ak-Tel.

Modeling Tip
Modeling NO2 in AERMOD – ARM2
One of the biggest changes to the AERMOD modeling system in the 18081 model update was the removal of the original Ambient Ratio Method (ARM) for analyzing conversion of NOx to NO2. This option, based on Chu & Meyer’s 1991 work presented at that year’s Air & Waste Management Association’s annual conference, used a single ratio to convert all NOx concentrations to NO2. The national default value was 75% for annual averages, and subsequent guidance recommended a value of 80% for the hourly standard.
The removal of ARM leaves the Ambient Ratio Method 2 (ARM2) as the only regulatory Tier 2 modeling demonstration. Let’s take a closer look at this model option.
The Ambient Ratio Method 2 was added as a BETA option to AERMOD as part of the 13350 model update. It was based on work done by Podrez (Atmospheric Environment, 2015) in which a 10-year record of ambient data from the Air Quality System was analyzed to characterize typical NO2/NOx ambient ratios. When analyzing the 98th percentile values for the entire AQS data set, the resulting plot demonstrated a polynomial fit upon which the ARM2 conversion factor equation was developed.
98th Percentile NO2/NOx Ambient Ratios as Calculated by ARM2
These calculated ratios were constrained to a maximum of 0.90 (based on the current EPA recommendation for maximum equilibrium ratio) and a minimum value of 0.20 (based on data analysis and consideration of typical in-stack ratios).
Current guidance from the U.S. EPA recommends a minimum ratio of 0.50 to maintain an appropriate level of conservatism in the results.
To enable ARM2 in AERMOD View™, proper option selection must be made on the Control Pathway.
- On the Pollutant/Averaging options, select NO2 from the Type drop-down list.
- On the NOx to NO2 Options, select the ARM2 option from the Tier 2 group. Options are available to modify the Minimum and Maximum NO2/NOx Ratios, but these values are constrained to an absolute minimum of 0.50.

Articles
EPA Announces Effort to Update Wet Weather Regulations for Wastewater Treatment Plants
May 24, 2018 - The U.S. Environmental Protection Agency (EPA) announced it will be reaching out to states, local communities, and stakeholders as the Agency begins a new rulemaking process to provide certainty surrounding the use of “blending” by wastewater treatment plants.
“EPA is taking action on a new rule that will give municipalities much-needed clarity on blending at wastewater treatment plants,” said EPA Administrator Scott Pruitt. “We look forward to engaging with partners at the state and local levels as we work to design a rule that offers a common-sense approach to protecting public health and safely managing our nation’s wastewater.”
What Does the Future of Energy Look Like? Stanford Scientists Weigh In
May 24, 2018 - Fossil fuels like coal, oil and natural gas supply 80 percent of the world’s energy to warm homes, charge devices and power transportation. They are also the primary human source of greenhouse gas emissions. Stanford scientists broadly agree that curtailing our use of fossil fuels would have significant benefits – like improving health and reducing the number and severity of natural disasters – but it’s not yet clear what can replace them.
Wind and solar are increasingly popular sources of energy, but the sun does not always shine, and the wind doesn’t always blow. Batteries to store their intermittent energy are not yet cheap and powerful enough to fill the gaps. Nuclear energy produces no greenhouse gases directly, but the current generation of reactors has other problems. Solutions like storing carbon dioxide underground or turning it into clean fuel are promising, but they also need much development. None of the possible solutions is without challenges.
Most-Polluting Wood Burners Could be Banned in Effort to Improve UK Air Quality
May 22, 2018 - The government is planning to bring in tougher regulations on household wood burners and fires in a bit to cut UK air pollution.
New legislation will mean that only cleaner fuels and stoves will be sold for domestic heating, under the proposals being put out for consultation.
Councils will also be given new powers to bring in "clean air zones" by limiting what people can burn or bringing in "no-burn days".
Carbon Satellite to Serve as an Important Tool for Politicians and Climate Change Experts
May 8, 2018 - A new satellite that measures and provides detailed carbon balance information is one of the most important new tools in carbon measurement since infrared light, believe researchers from the University of Copenhagen. The researchers expect the satellite to be a valuable tool for the UN’s work on climate change related to the Paris climate accord.
Carbon balance is important for climate and environment because whenever carbon is converted into carbon dioxide, CO2 emissions increase. On the other hand, carbon is an essential aspect of life on Earth: a felled tree releases carbon into the atmosphere whereas a planted one takes up carbon in vegetation and soil. A lack of carbon in vegetation and soil can create a carbon imbalance and have climate-related consequences.
Study: Health Benefits Will Offset Cost of China’s Climate Policy
April 30, 2018 - A new MIT study reports that if China follows through with its international pledge to reduce carbon dioxide emissions, every one of its provinces will experience benefits to air quality and human health, with associated monetary savings that could offset the total cost of implementing the climate policy.
The study, published today in Nature Climate Change, estimates that by meeting its greenhouse gas-reduction goals, China would simultaneously improve its air quality, which would avoid a significant number of deaths due to air pollution, across every province. Fewer deaths from air pollution means a benefit for society that can be quantified — a $339 billion savings in 2030 that the researchers estimate could be about four times what it would cost China to meet its climate goals.
