NASA Scientist Imhoff to Give Sigma Xi Public Lecture

Dr. Marc Imhoff, project scientist from NASA’s Goddard Space Flight Center, will speak Tuesday, April 27, 2010, at 7:30 p.m. in Eberly Auditorium. This presentation is free and open to the public.

His talk, “Gray Wave of the Great Transformation: A Satellite View of Urbanization, Climate Change, and Food Security,” is sponsored by the IUP chapter of Sigma Xi, a multidisciplinary research society.

Imhoff works in the Earth Sciences Division at NASA’s Goddard Space Flight Center as the project scientist for Terra, NASA’s flagship Earth observing system mission. As Terra project scientist, Imhoff coordinates an international research team using Terra and other instruments to study Earth’s changing atmosphere, oceans, and land surface.

He has personally conducted research on a wide range of topics including the impact of urbanization on biodiversity and food security, urban heat islands and climate, and carbon accounting using remote sensing for the Kyoto Protocol. He was a primary developer of the nighttime satellite imagery showing Earth’s cities at night and pioneered the use of radar sensors for terrain and vegetation mapping.

Imhoff holds a B.S. degree in physical geography and an M.S. degree in agronomy from Pennsylvania State University and a Ph.D. in biological sciences from Stanford University.

Imhoff was integral in the creation of the famous NASA image composite showing the Earth at night:
