Measurements and Modeling of Net Carbon Exchange over a Southeastern Loblolly Pine Plantation at the

Duke Forest AmeriFlux Site

The project has two main objectives: To quantify the net flux of CO₂(Fc) to/from a loblolly pine ecosystem at a temporal resolution of

30 minutes so that the net fluxes at longer time intervals can be calculated. Furthermore to estimate canopy photosynthesis(GPP)

through measurements of canopy CO₂ storage via an existing 10 level CO₂ profiling system and CO₂ efflux from the soil with chamber

measurements. The second objective was to quantify the effect of vegetation structure, microclimate, soil moisture, physiology,

 and soil efflux processes on variability in net CO₂ exchange
