Greenhouse Gas Dynamics

As part of its regular research programs, the Division of Chemistry will consider proposals for studies related to the production, interaction, and reactions of greenhouse gases (GHGs). Research focused on laboratory investigation of processes at the molecular level, development of experimental data necessary for effective modeling and prediction of greenhouse gas effects on a global scale, and identification of alternative, less environmentally destructive substances.

Description

Greenhouse Gas Dynamics (GGD) includes research on the complex chemical processes, both natural and industrial, which lead to GHG production and release, and on the interactions of greenhouse gases with light, other atmospheric gases, surfaces, and other relevant substances.

Photochemical studies of greenhouse gases, undertaken because of environmental relevance, have revealed much about the reaction chemistry of isolated gases. The complex nonlinear interactions of multiple gases and phases, however, are only vaguely understood despite their clear climatic importance. Photochemical studies aimed at improving understanding of the behavior of complex systems are encouraged.

Only recently has it been appreciated that a combination of mass and thermal transport, photochemistry, and surface chemistry is necessary to describe interactions of GHGs in the atmosphere. This program supports investigations of adsorption, photochemistry, and bulk reactions between GHGs and other substances--frequently at surfaces or in aerosols or hydrosols--which determine their environmental impact on global climate change. Surface interaction studies which point to new and effective means for selectively removing GHGs from process streams or catalyzing their conversion to innocuous substances are also appropriate.

Proposals for development of new physical and chemical tools to carry out analyses essential for characterization of environmentally critical interactions will be considered. Attention will be given to developing reliable techniques for in situ sensing and quantification of GHGs and understanding fundamental chemistries underlying passive and active sensor design.
