Eichinger Gets $199,000 U.S. Army Grant Supporting Aerosol Emissions Study

William Eichinger, professor of civil and environmental engineering in the University of Iowa College of Engineering, faculty research engineer at IIHR-Hydroscience & Engineering and researcher in the Center for Global & Regional Environmental Research, has received a one-year, $199,000 U.S. Army grant to secure a helicopter observation platform for use with an on-going National Science Foundation (NSF) investigation of the nature of smog in Mexico City.

In October 2005, Eichinger received a two-year, $322,000 NSF grant to investigate the chemical composition of smog in Mexico City. The project uses laser radar (lidar) to measure the chemical and physical changes in pollutants emanating from Mexico City -- currently the world's second largest metropolitan area -- and, eventually, help mitigate the effects of atmospheric emissions.

Eichinger said the grant would make possible more accurate measurements of aerosol characteristics and transport.

"The lidar will be mounted on a helicopter. This will enable the lidar to cover much larger areas than is currently possible from the ground," says Eichinger, noting that the project is part of a long-term collaboration with Duke University. "It would also be especially valuable in an urban environment, for example, where line-of-sight visibility is limited from the ground. The combination of helicopter, lidar, and meteorological instruments will enable researchers to use the lidar to find areas of interest and then use the helicopter to place conventional instruments at that location to examine it in detail."

In addition to the Mexico City smog study, Eichinger also is currently conducting a three-year, $406,000 U.S. Department of Agriculture study to develop a new approach to rid animal husbandry facilities of methane and other emissions.

Eichinger, who earned his doctorate in hydrologic science from the University of California-Davis in 1995 and joined the UI faculty in 1997, has specialized knowledge in the fields of hydrology and fluid mechanics in the environment, atmospheric pollution control and remediation, optical remote sensing, lidar and nuclear physics.
