HAMPTON, Va. -- Air pollution in the United States impacts human health, costs American farmers billions of dollars annually in crop loss and reduced productivity, and decreases the vitality of U.S. forests especially in the east.
Dr. Jack Fishman, a senior research scientist in the Science Directorate at NASA's Langley Research Center, will speak at Thomas Nelson Community College at 7 p.m. on April 21, 2009, as part of NASA's weeklong celebration of Earth Day. Sponsored by the Chemistry Department, Fishman's talk will be in the Espada Conference Center of the Hampton campus. It is free and open to the public.
Entitled "Satellite Observations of Air Pollution: Local Impacts Seen from a Global Perspective," the talk will focus on how NASA scientists have used satellite measurements to observe and understand the complex interaction between local sources of pollution and how the Earth's atmosphere has been modified on a global scale.
Since the 1970s, scientists and engineers at NASA Langley have been in the forefront of measuring air pollution from space. They are developing the next generation of instruments to better understand the mechanisms that lead to widespread air pollution episodes and to better forecast the impact of such events.
Fishman has been a research scientist for 35 years studying the composition of the troposphere and developing computer models that provide insight into the processes controlling atmospheric chemistry. For the past two decades, he has been a pioneer in the use of existing satellites to study global pollution. Fishman is currently working toward the development of NASA's next generation satellites devoted to measuring air pollution.
At NASA Langley, Science Directorate researchers are working to find answers to questions that affect the health of the planet and the people on it. For more information:
