Modeling Tip
Puff Tracking in CALPUFF View™
CALPUFF is an air dispersion model that advects ‘puffs’ of material emitted from modeled sources, simulating dispersion and transformation processes along the way. These puffs can be displayed graphically using debug information written to the main CALPUFF output file (CALPUFF.LST). With CALPUFF View, modelers can visualize puffs as animations in Google Earth.
NOTE: The Puff Tracking option produces a very large CALPUFF.LST file that can reach many gigabytes in size. Therefore, you should set the modeling period for this option to a small number of days in case the CALPUFF model is being run for a longer period of time.
Setting Up Puff Tracking
Step 1: Select the menu option CALPUFF | Output Options and then click on the Puff Tracking tab.
Step 2: Check the box for the Output Debug Option (DEBUG.DAT) to write puff parameters to the output file.
Step 3: Specify the number of Puffs to Track. If more puffs are emitted in the modeling period than the number tracked, the animation will stop upon reaching the highest tracking number.
Step 4: Identify the Modeling Period. You can select the date in YYYY/MM/DD HH:MM:SS format or select how many Met Periods to process. Period length depends upon the Time Step selected in the CALPUFF | Run Information options. For example, if your time step is 3600 seconds (1 hour), then each Met Period represents a single hour.
Puff Tracking Options in CALPUFF View
After successfully completing a CALPUFF model run, the puffs can be exported for animation.
Animating Puffs
Step 1: Select Export | Google Earth from the menu.
Step 2: Select the folder in which to save the KML files; by default, the folder is named
Step 3: In the Layers to Export list, make sure the Puffs Representation layer is checked. Leave checked any other layers that you wish to include in the exported KML file. Click the checkbox to uncheck any layers that you do not wish to include.
Step 4: Click the Export button. If the Launch Google Earth Automatically option is selected and Google Earth is installed on your computer, the program will begin loading.
Step 5: The Google Earth application opens displaying all the CALPUFF View layers for your project. To start the Puff Tracking animation, you need to press the button. For animation settings, press the button.

Global Warming Being Slowed by Volcanic Eruptions
March 2, 2013 - A team led by the University of Colorado Boulder looking for clues about why Earth did not warm as much as scientists expected between 2000 and 2010 now thinks the culprits are hiding in plain sight -- dozens of volcanoes spewing sulfur dioxide.
The study results essentially exonerate Asia, including India and China, two countries that are estimated to have increased their industrial sulfur dioxide emissions by about 60 percent from 2000 to 2010 through coal burning, said lead study author Ryan Neely, who led the research as part of his CU-Boulder doctoral thesis. Small amounts of sulfur dioxide emissions from Earth’s surface eventually rise 12 to 20 miles into the stratospheric aerosol layer of the atmosphere, where chemical reactions create sulfuric acid and water particles that reflect sunlight back to space, cooling the planet.
Canada Continues to Align Greenhouse Gas Emissions Measures with the United States
MISSISSAUGA, ONT - February 25, 2013 - Today the Honourable Peter Kent, Canada’s Environment Minister, announced final regulations to improve fuel efficiency and reduce greenhouse gas (GHG) emissions from new on-road heavy-duty vehicles and engines. This is another step in our plan to align our environmental regulations with the United States.
“With these tough new measures, GHG emissions from 2018 model-year heavy-duty vehicles will be reduced by up to 23 per cent,” said Minister Kent. “The regulations will also lead to improved fuel efficiency. For example, a semi-truck operator driving a 2018 model-year vehicle will save up to $8,000 per year in fuel.”
The Regulations will establish progressively more stringent standards for 2014 to 2018 model-year heavy-duty vehicles such as full-size pick-ups, semi-trucks, garbage trucks and buses. The Regulations will remain in full effect for all subsequent model-year vehicles, which will be required to adhere to the 2018 standard, and will result in GHG reductions of 19.1 megatonnes over the lifetime of the 2014-2018 model-year vehicles.
EPA Updates Greenhouse Gas Emissions Data from Large Facilities
WASHINGTON - February 5, 2013 - Today, the Environmental Protection Agency (EPA) posted the second year of greenhouse gas (GHGs) emissions data on its website, which provides public access to emissions data by sector, by greenhouse gas, and by geographic region such as county or state.
Greenhouse gases are the primary driver of climate change, which can lead to hotter, longer heat waves that threaten the health of the sick, poor or elderly; increases in ground-level ozone pollution linked to asthma and other respiratory illnesses; as well as other threats to the health and welfare of Americans.
“Transparency ensures a better informed public, which leads to a better protected environment,” said Gina McCarthy, assistant administrator for EPA’s Office of Air and Radiation. “With this second data release, communities, businesses and others can track and compare facilities' greenhouse gas emissions and identify opportunities to cut pollution, minimize wasted energy, and save money.”
Newly Found Health Effects of Air Pollution Call for Stronger EU Air Policies
January 31, 2013 - Long-term exposure to fine particles (PM2.5) can trigger atherosclerosis, adverse birth outcomes and childhood respiratory diseases, according to a World Health Organisation (WHO) review released today. REVIHAAP – the “Review of evidence on health aspects of air pollution” – also suggests a possible link with neurodevelopment, cognitive function and diabetes, and strengthens the causal link between PM2.5 and cardiovascular and respiratory deaths. The research was carried out at the request of the European Commission in the framework of the 2013 review of the European Union’s air policy.
EU Commissioner for Environment Janez Potocnik said: “EU air policy must be based on the latest science. That is why I asked the WHO to undertake this research. The links it has found between air pollution and human health reinforce the case for scaling up our policy: it will be a key input to the 2013 air quality policy review”.
“Only a few years ago in the absence of clear evidence, air pollution standards and regulations were not sufficiently targeting human health”, said Zsuzsanna Jakab, WHO Regional Director for Europe. “Years of WHO-coordinated research have provided the first quantitative estimates of the burden of disease from particulate matter and have now established links between air pollutants and health outcomes. We are confident that this new knowledge will ultimately lead to more stringent air pollution control policies to protect the health of European citizens”.
Environment: A Fresh Legal Approach to Improving Air Quality in Member States
January 24, 2013 - Ambient air quality is poor in many EU Member States – despite an obligation for governments to ensure good air quality for citizens. The situation is so serious that the Commission is currently taking action against 17 States with a consistent record of poor air quality.
Today, as part of a fresh approach to the problem, Bulgaria, Latvia and Slovenia are being asked to urgently address an on-going issue that kills more citizens than road traffic accidents every year.
The problem concerns tiny particles known as PM10s, which can cause respiratory problems, lung cancer and premature death. Poor air quality is a direct threat to citizens exposed to pollution from fine particles (PM10), which originates from sources such as road traffic, industrial activity and domestic heating. According to the latest research, a majority (56 %) of Europeans believe that air quality has deteriorated in the last 10 years (see IP/13/6).
In the past, the Commission has successfully taken Italy, Portugal, Slovenia and Sweden to Court for failing to ensure good air quality for citizens. But the Court rulings that resulted only covered the failure to comply with air quality limit values in the past, providing little incentive for Member States to act on future exceedances.
