The role of landscape structure on biosphere-atmosphere interactions: Enhancing the knowledge of regional BVOC's emissions

Project Abstract: 
Understanding the role that landscape plays in the production of biogenic emissions is important for air quality management. The aim of this project is to study biogenic emissions from a landscape ecology point of view. It is known that light and temperature are factors that control the emissions of terpenes. Therefore, it is possible that a more fragmented landscape will produce more emissions, if the BVOC's emitters happen to be on the edges and receiving more solar radiation. Using the land-cover as a tool of determining where the emissions are produced will bring a new perspective for the atmospheric scientist. Taking in consideration the position of the plants (inside the forest or in the edge of the forest) may show that it is necessary to take in consideration the tree positioning to create an accurate BVOC's emission inventory for use in atmospheric models. We will determine how BVOC's are distributed within different species, and correlate the spatial (and temporal) distribution of the emissions with those plants. We will be scaling leaf-level measurements to regions, via landscape composition and structure by combining parameters such as leaf area indices (LAI), biomass, vegetation coverage, and canopy layering with emissions rates and algorithms in a spatial model. The model will give us the possible outcomes of a landscape change in biogenic emissions, and will help us with future management decisions
