Automated Multi-Angular Spectroradiometer (AMSPEC) Network for Estimation of Light Use Efficiency (LUE)

植物的生理过程是高度动态的，并且随着植物对变化的环境条件的响应而随空间和时间变化。监测植物对这些压力的反应的一个关键方法是使用遥感设备。在这个RTI提案中，我们要求资金建立AMSPEC仪器，使自动连续窄波段观测，以多角度的方式获得。该系统还包括一个网络摄像头，将这些测量结果与树冠的物候变化联系起来，从而可以全年收集全面的数据。我们建议将这些仪器定位在一系列至关重要的加拿大植被类型，详细的碳交换测量正在进行中。一个成功的建议将使我们能够获得数据，以整合我们的知识，从树木生理学，遥感，林业和生物统计学和更好地预测树冠结构对树木生理反应的影响，气候和环境变化。最终，这项研究将提高国家和全球尺度森林碳积累模型的准确性和精度。

Plant physiological processes are highly dynamic and can vary over space and time as plants respond to changing environmental conditions. One key way to monitor the responses of plants to these stresses is using remote sensing devices. In this RTI proposal we request funds to build AMSPEC instruments which allow automated continuous narrow waveband observations to be acquired in a multi-angular fashion. The system also includes a webcam to link these measurements to phenological changes in the canopy thereby allowing comprehensive data collection year round. We propose locating these instruments at a range of critically important Canadian vegetation types, where detailed carbon exchange measurements are underway. A successful proposal will allow us to obtain data to integrate our knowledge from tree physiology, remote sensing, forestry, and biometrics and better predict the impact of canopy structure on tree physiological responses to climate and environmental change. Ultimately this research will improve the accuracy and precision of national and global scale forest carbon accumulation models.
