Smart Sensors for Wildfire Detection 

Wildfires are growing in intensity and frequency as the climate changes, draining resources for firefighting often early in the season. Traditional methods of fire towers or satellite imaging are not effective until  fires are of substantial size. Air Sciences intern Mikhail Mayers, a computer engineering student at Portland State University, is working with some other students to detect smaller fires sooner.  Read more

Tillage and Roughness Mapping

Soil erosion from wind has plagued agriculture for centuries. More recently, mining operations, construction, and water diversion projects have been facing similar problems. Eroded soil can become suspended in the atmosphere and lead to violations of National Ambient Air Quality Standards (NAAQS) regulated by the Environmental Protection Agency (EPA). 

For industry, the most common solution is watering the ground, which increases soil cohesion and reduces dust emissions. Water, though, is often in short supply or prohibitive in cost. For this reason, Air Sciences is using industrial-scale tilling methods to inhibit dust emissions in complex regulatory environments. The solution is water-free, inexpensive, monitorable, and maintainable.

Automating Environmental Data Reporting

Reporting environmental data can feel a lot like the “old days” in so many ways. Regardless of improvements in instrument technology, the data and reporting requirements don’t change. What has changed though is the potential to make the data flow automatically into your regular reporting. That’s right, flow. Automatically.

The Regional Haze Rule, Part II

Characterizing Wildfire

In our previous post on the Regional Haze Rule (RHR), we briefly explored the history of the rule and how recent changes in the rules and accompanying guidance have implications for how wildland fires are handled during the planning process. Here, we will look more closely at the implications of wildland fire on regional haze planning, and how Air Sciences is assisting the Western Regional Air Partnership (WRAP). WRAP is a voluntary partnership of states, tribes, federal land managers, local air agencies and the U.S. Environmental Protection Agency (EPA) whose purpose is to understand current and evolving regional air quality issues in the Western United States.

The Regional Haze Rule, Part I  

Then and Now

Promulgated in 1999 in the wake of the bipartisan Grand Canyon Visibility Transport Commission’s recommendations, the Environmental Protection Agency (EPA) Regional Haze Rule established visual (instead of health-based) criteria for air quality to address declining visibility. The areas subject to this rule span the larger Class I national parks and wilderness areas (156 in total) overseen by the National Park Service, U.S. Fish and Wildlife Service, U.S. Forest Service, and several Native American Tribes.
