RUI: Methane Emission, Net Ecosystem CO2 Exchange and Remote Sensing Relationships in Subtropical to Boreal Wetlands

9527698监测地球系统和大气之间痕量气体（特别是温室气体）的交换将提供一种手段来评估未来气候条件下人为排放变化的有效性。 遥感技术有潜力提供监测能力，以估计湿地的二氧化碳交换（初级生产）和甲烷排放量。 为了利用遥感作为一种准确的预测工具，估计甲烷排放量的各种湿地，系统地比较甲烷排放量，初级生产力和遥感关系的大纬度将是一个重要的一步。 本项目将研究这些关系内和三个主要湿地系统之间的选择沿着一个广泛的纬度梯度（25 N至60 N）：亚热带大沼泽地，昂贵的沼泽西南路易斯安那州，北方泥炭地的阿尔伯塔和西北地区。 该项目应产生适用于区域乃至全球范围内与人类活动和气候变化的相互作用有关的一系列广泛问题的结果。

9527698 Whiting Monitoring athe exchange of trace gases (especially greenhouse gases) between terrestrial systems and the atomsphere will provide a means to assess the effectiveness of changes in anthropogenic emissions of future climatic conditions. Remote sensing technology has the potential to provide monitoring capabilities in estimating carbon dioxide exchange (primary production) and methane emission from wetlands. To utilize remote sensing as an accurate predictive tool in estimating methane emissions form a variety of wetland, a systematic comparison of methane emission, primary production and remote sensing relationship across large latitudinal will be an important step. This project will examine these relationship within and among three primary wetland systems chosen along a wide latitudinal gradient (25 N to 60 N): the subtropical Everglades, the expensive marshes of southwestern Louisiana, and the boreal peatlands of Alberta and Northwest Territories. The project should produce results applicable to a broad suite of questions at regional-t-global scales having to do with the interaction of human activity and climate change.
