Biosphere/Atmosphere Interactions

Objectives:

  1. To understand the processes governing atmospheric oxidation of species emitted by the forest in the presence of nitrogen oxides.
  2. To understand the mechanism of isoprene, alpha pinine, and other biological volatile organic compounds oxidation and the behavior and identification of the secondary products, such as aldehydes, ketones, and organic nitratea.
  3. To quantify nitrogen deposition in a forest environment and understand how the deposited nitrogen affects photosynthetic rates and carbon sequestration.
  4. To understand the nitrogen composition and processing within clouds and the role it plays in changing the composition and relative rates of dry and wet deposition to a forest.
  5. To contribute useful ecosystem scale carbon dioxide flux measurements to current and future global climate models.
