Project Overview
Project Abstract: 
The Program for Research on Oxidants: PHotochemistry, Emissions, and Transport (PROPHET) was created in 1996, as a coordinated research effort aimed at investigation of the relationships between atmospheric odd nitrogen, ozone, and forest-atmosphere interactions. The motivating science questions for PROPHET are described below. - How well do we understand the relationships between nitrogen oxides concentrations and ozone production efficiency in the midwest? - Do we understand the partitioning of nitrogen, and are there missing or uncharacterized atmospheric nitrogen sinks? - How well do we understand the role of biogenic volatile organic compounds (BVOCs) with respect to ozone formation, and atmospheric nitrogen sequestration? - What is the impact of ozone deposition on forest productivity? - Do we understand the environmental controls on BVOC emissions, and can they be adequately simulated?
