A brief overview of air quality and transportation trends in the Portland Metro Area.

As sensor technology becomes more accessible, the development of low cost data collection systems is becoming more useful for both professional research and citizen science. This thesis explores the social and...

Background: There is increasing concern about the impact of air quality on human health in urban environments and how to best reduce impacts through public policies. An NSF Biocomplexity Project - "Feedbacks...

Reducing exposure to degraded air quality is essential for building healthy cities. Although air quality and population vary at fine spatial scales, current regulatory and public health frameworks assess human...

The City of Portland is exploring how distributed "Internet of Things" (IoT) sensor systems can be used to improve the available data that is usable by city engineers, planners, and the public to help inform...

Congested traffic corridors in dense urban areas are key contributors to the degradation of urban air quality. While waiting at bus stops, transit patrons may be exposed to greater amounts of vehicle-based...

This Atlas draws on the Portland Air Toxics Assessment (PATA) study to explore the regional variation of air quality. The PATA study presents an extraordinary opportunity to think about how the creation of new...

Bioenergy is expected to play an increasingly significant role in the global energy budget. In addition to the use of liquid energy forms such as ethanol and biodiesel, electricity generation using processed...

Atmospheric particulate matter is known to have significant effects on human health, visibility, and global climate. The magnitudes of these effects, however, depend in complex ways on chemical composition,...

Urban arterial corridors are landscapes that give rise to short and long-term exposures to transportation-related pollution. With high traffic volumes, congestion, and a wide mix of road users and land uses at...
