Dissertation Research: Multi-Scaled Modeling of Net Primary Productivity in a Temperate Deciduous Forest

印第安纳大学博士论文的研究将包括对大气和陆地碳循环之间动态相互作用的分析。建立能对这些系统有更深入了解的模型的一个困难之处在于，对碳库和通量大小进行测量的尺度与必须对其进行外推的尺度截然不同。具体来说，这项研究将利用地面调查和实验、一个冠层上二氧化碳通量塔和两颗不同的遥感卫星的数据，在若干空间和时间尺度上模拟这些相互作用。结果将是一个空间明确的森林净生产力数学模型，因为它在印第安纳州南部森林景观中随生物和非生物梯度而变化。

Jerry J Johnston Indiana University The doctoral dissertation research will involve an analysis of the dynamic interactions between the atmosphere and the terrestrial carbon cycle. A difficulty in creating models which provide a deeper understanding of these systems has been the drastically different scale at which measurements of carbon pool and flux sizes have been made and the scale to which these must be extrapolated. Specifically the research will simulate these interactions at a number of spatial and temporal scales using data from ground based surveys and experiments, an above-canopy carbon-dioxide flux tower, and two different remote sensing satellites. The result will be a spatially explicit mathematical model of forest net productivity as it varies with respect to biotic and abiotic gradients present in the forested landscape of southern Indiana.
