UC Irvine researchers are leading the effort to understand the causes and effects of one of the worlds leading environmental problems -- air pollution. They are studying both regional and worldwide air pollution issues, ranging from the effects of freeway exhaust to the role dust storms and forest fires may play. UCI is also involved in a large-scale commuter transportation project designed to cut back on auto emissions and is home to the Air Pollution Health Effects Laboratory, which continues to increase understanding of the risks air carcinogens present to children. Here are a few current research projects of note.
Large Scale Forest Fires Also Raise Ozone Pollutant Levels
The product of the large-scale forest fires that have plagued the Western United States is easy to see -- thick, dark smoke filling the skies. But downwind, gaseous emissions from fires create a pollutant invisible to the eye, but no less dangerous - ozone. Atmospheric chemist Donald Blake, who studies the impact of biomass burning on the atmosphere, says that when sunlight combines with nitrogen oxides and hydrocarbons in the smoke, resulting chemical reactions form ozone, and lots of it. These enhanced concentrations of ozone can blow around for several weeks, Blake adds. The result is air quality downwind from fires that can reach hazardous levels. Ozones effect on humans can range from eye irritation to worsening existing lung conditions such as asthma.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
