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.

9527698 Whiting 监测陆地系统和大气之间痕量气体（特别是温室气体）的交换将提供一种评估未来气候条件人为排放变化的有效性的方法。 遥感技术有潜力提供监测能力，估算湿地的二氧化碳交换（初级生产）和甲烷排放。 为了利用遥感作为准确预测工具来估算各种湿地的甲烷排放量，系统比较大纬度范围内的甲烷排放量、初级生产和遥感关系将是重要的一步。 该项目将研究沿宽纬度梯度（北纬 25 至 60 度）选择的三个主要湿地系统内部和之间的关系：亚热带大沼泽地、路易斯安那州西南部昂贵的沼泽以及阿尔伯塔省和西北地区的北方泥炭地。 该项目应产生适用于区域到全球范围内与人类活动和气候变化相互作用有关的一系列广泛问题的结果。
