Modeling Tip

Automated Coastline Download in CALPUFF View

One feature of the CALPUFF model is the ability to depict coastal interaction effects. Since the land surface can heat more rapidly than adjoining water, a Thermal Internal Boundary Layer (TIBL) can form and bring elevated source plumes close to the ground. This sets up a potential coastal fumigation scenario.

In order for the model to accurately depict the TIBL at a sub-grid scale (i.e., within a single grid cell), the user must define the line which divides the land and water surfaces. The coastline must reside in grid cells where overland and water land use categories border each other. Accurate depiction of the coastline is necessary for CALPUFF’s internal mechanisms.

To this end, Lakes Environmental enhanced the CALPUFF View application to support automatic download of high-resolution coastline data from the WebGIS database. Data are downloaded in the National Oceanic and Atmospheric Administration GSHHG database format and converted to a CALPUFF-supported coastline file. To download the data, follow the steps below:

Step 1: Set up a CALPUFF View project or open an existing project.

Step 2: Select the Import | Coastlines | From WebGIS... menu option.

Step 3: Select the coastline extents. Choose between a user-defined radius extending from all sources or over the entire meteorological grid.

Step 4: Visually verify the downloaded coastline and click OK.

When the CALPUFF model is executed, the sub-grid TIBL processing routine will be automatically enabled.

EPA Finalizes Rule to Reduce Climate-Damaging HFCs

July 2, 2015 - WASHINGTON- Today, the U. S. Environmental Protection Agency (EPA) is finalizing a rule to prohibit certain uses of chemicals that significantly contribute to climate change in favor of safer, more climate-friendly alternatives. This action responds to President Obama's Climate Action Plan by reducing emissions of hydrofluorocarbons (HFCs), a class of potent greenhouse gases used in air-conditioning, refrigeration, and other equipment.

New Canadian Air Quality Index Helps Those at Risk Understand Impacts

June 26, 2015 - A simplified air quality index will make it easier for local residents with health conditions that put them at risk in bad weather to understand what precautions should be taken to protect themselves.

"The scale really helps Canadians understand how the outdoor air affects their health," said Carly Warnock, public health planner for Region of Waterloo Public Health.

Emissions from Canada's Oil-Sand Crude Higher Than Those from U.S. Sources

June 25, 2015 - Gasoline and diesel fuel extracted and refined from Canadian oil sands will release about 20 percent more carbon into the atmosphere over the oil's lifetime than fuel from conventional crude sources in the United States, according to a study by the U.S. Department of Energy’s Argonne National Laboratory; the University of California, Davis; and Stanford University.

The researchers used a life-cycle, or “well-to-wheels,” approach, gathering publicly available data on 27 large Canadian oil sands production facilities. The study, published in the journal Environmental Science and Technology, found the additional carbon impact of Canadian oil sands was largely related to the energy required for extraction and refining.

EPA, DOT Propose Greenhouse Gas and Fuel Efficiency Standards for Heavy-Duty Trucks

June 19, 2015 - WASHINGTON - The U.S. Environmental Protection Agency (EPA) and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) are jointly proposing standards for medium- and heavy-duty vehicles that would improve fuel efficiency and cut carbon pollution to reduce the impacts of climate change, while bolstering energy security and spurring manufacturing innovation.

The proposed standards are expected to lower CO2 emissions by approximately 1 billion metric tons, cut fuel costs by about $170 billion, and reduce oil consumption by up to 1.8 billion barrels over the lifetime of the vehicles sold under the program. These reductions are nearly equal to the greenhouse gas (GHG) emissions associated with energy use by all U.S. residences in one year. The total oil savings under the program would be greater than a year’s worth of U.S. imports from the Organization of the Petroleum Exporting Countries (OPEC).

EU Considering New Limitations on Diesel Engines in Non-Road Machinery

June 3, 2015 - As air pollution spikes in Europe’s cities prompt car-free days and talk of banning diesel cars, it’s easy to forget the other culprits behind the air quality crisis: diesel machines. Known in legislation by the innocuous term ‘non-road mobile machinery’, their air pollutant emission limits are now finally under revision.

The last directive dated back to 1997 and the new rules will set standards for decades to come. Air pollution is causing more than 450,000 premature deaths every year in Europe and a recent Eurobarometer survey confirmed that air pollution is now the biggest environmental concern of European citizens. Efficient regulation of emissions sources is therefore key to mitigating the exposure of citizens to air pollution.
