Recent US EPA Memoranda
The US EPA has recently released several memoranda concerning the use of CALPUFF and AERMOD models. These memoranda are listed below and can also be viewed on the US EPA SCRAM website.
Memorandum 1: Clarification on the EPA-FLM Recommended Settings for CALMET
AUGUST 31, 2009 - This memorandum updates the draft recommendations for CALMET settings. In particular it addresses issues with the previous recommendations for CALMET settings with the use of prognostic meteorological data, which may have had a negative impact on the model performance. A full table of recommended CALMET settings is provided.

Memorandum 2: Use of Non-Default Radius for Determining Surface Roughness Length for AERMET
SEPTEMBER 17, 2009 - This memorandum discusses a request for the use of a non-default radius for determining surface roughness length for AERMET modeling. The request is based on a change in surface roughness just beyond the default 1km radius, and the merits of this request are discussed.

Product Spotlight - FETS View™
Facility Emissions Tracking System
FETS View is a powerful customizable software solution that integrates a facility-wide emissions inventory tracking system with air dispersion modeling. FETS View allows a facility to manage a large number of emission sources and pollutants in one, easy-to-use interface.
The emission and source data stored in the system is used to perform AERMOD or CALPUFF air dispersion modeling to demonstrate compliance with environmental regulations. This solution allows you to model for different types of emissions and averaging times, screen out negligible sources, and choose from many other modeling and formatting options. Once your modeling is complete, FETS View’s detailed integrated GIS and graphics make it easy to view modeling results for your site, analyze impacts and present results to key stakeholders.
FETS View’s Key Features:
- Highly organized structured hierarchy for entering and managing large volumes of site data
- Integration of the emissions inventory and air dispersion modeling components eliminating the need to import and export model files with external applications
- Ability to maintain unlimited model scenarios and inventory cases
- Robust batch mode processing option
- Integrated U.S. EPA TANKS modeling
- Integrated U.S. EPA emission calculators including AP-42, EIIP, and NEI
In addition, a wide variety of pre-defined reports assists you in documenting your compliance with local air pollution regulations. Your results are presented professionally using FETS View’s highly customizable contour plotting capability for visualization of the pollutant impacts. Reports and plots can be effortlessly exported into several commonly used formats.

Modeling Tip
Varying Exit Temperatures of Point Sources in AERMOD
In order to regulate your stacks' temperatures throughout the year, it is recommended that you use "hourly emission files" in AERMOD View.
There may be times that you are presented with a simplified case. In this instance, the following work around would be applicable. This will avoid the labor intensive process of creating an hourly emission file.
Problem:
Variable emissions will let you change emission factors but will not permit the user to define different operating temperatures.
Solution:
- Create 2 identical stacks at the same location (e.g., STACK-1A and STACK-1B)
- For STACK-1A specify the first operating temperature A
- For STACK-1B specify the second operating temperature B
- Go to the Variable Emissions dialog in the Source Pathway
- Choose the applicable emission period (season, month etc.)
Step 1 - Create an emission scenario for STACK-1A:
- Enter an emission factor of 1 (100%) for the time period which the first operating temperature (A) applies. Enter 0 (0%) for the remainder of the time.
Step 2 - Create an emission scenario for STACK-1B:
- Enter an emission factor of 1 (100%) for the time period which the second operating temperature (B) applies. Enter 0 (0%) for the remainder of the time.
Note: Please note this is a work around. It is always best to use an Hourly Emission file in case stack parameters, such as temperature, are variable.

New Carbon Dioxide Data Helps Unlock the Secrets of Antarctic Formation
ScienceDaily (Sep. 14, 2009) — The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study.
A team of scientists from Cardiff, Bristol and Texas A&M universities braved the lions and hyenas of a small East African village to extract microfossils in samples of rocks which show the level of CO2 in the Earth's atmosphere at the time of the formation of the ice-cap.

Another Factor that Impacts our Climate
September 13, 2009 - Just when we were getting confident that we understood the most important factors affecting the earth’s weather and climate, new research creates some surprises. UCLA atmospheric scientists have discovered a previously unknown basic mode of energy transfer from the solar wind to the Earth's magnetosphere. The research, federally funded by the National Science Foundation, could improve the safety and reliability of spacecraft that operate in the upper atmosphere. It could also help us understand the weather and previously unknown affects on our climate.

EPA to Review 79 Coal Mine Permits
September 11, 2009 - CHARLESTON, W.Va. - The Obama administration on Friday stepped up its efforts to curb environmental damage from surface coal mining, announcing plans to give 79 permit applications in four states additional scrutiny.
The Environmental Protection Agency said it wants to make certain the proposed mines won’t cause water pollution and violate the Clean Water Act. An initial review concluded all 79 probably would affect water quality and require additional study, the EPA said.
Forty-nine of the permits are for mines in Kentucky, the nation’s No. 3 coal-producing state. The list also includes 23 mines in West Virginia, the nation’s No. 2 producer behind Wyoming, six in Ohio and one in Tennessee.

India Could Halve Emissions Growth, at a Cost
September 10, 2009 – Growth in India's carbon emissions could be nearly halved by the year 2030 through the use of known practices and technologies, according to a new report from McKinsey & Company.
Through a "step-change in...efforts to lower emissions," India's carbon output could grow from 1.6 billion tons in 2005 to only 2.8 billion tons in 2030 as the country's population expands and its economy develops, the report said. This is down from a previously projected 5-6 billion tons for 2030.
