Please join the Chemistry and Physics departments for the seminar "Dynamics and Transport of Sulfur Dioxide in the North Pacific Troposphere," presented by Fang Huang "Jim" Tu, research scientist from Honeywell's Buffalo Research Lab, on Thursday, February 23, at 12:30 p.m. in Science and Mathematics Complex 173. All students, staff, and faculty are welcome.

Abstract
Sulfur dioxide (SO₂) plays an important role in the atmospheric sulfur cycle through the formation of new aerosol and the modification of existing aerosol. The major sources of SO₂ are anthropogenic fuel combustion and volcanoes. The reliance of East Asian nations on fossil fuels in their rapid development over the last three decades has led to concerns about the potential impact of SO₂ on the western Pacific troposphere. There are also concerns about the impact on global climate through the formation and modifications of aerosols and their effects on the radiation balance of the atmosphere. In 2001, NASA conducted the last global tropospheric experiment (GTE) for studying transport and chemical evolution over the Pacific (TRACE-P). This talk will present the data related to the dynamics and transport of SO₂ in the north Pacific troposphere collected during the TRACE-P campaign and provide a different point of view on  global climate change.
