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，可以随着时间和空间的变化而变化，因为植物对不断变化的环境条件做出了反应。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，我们要求资金建造AMSPEC仪器，该仪器允许以多角度的方式获得自动连续窄波段观测。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上，在那里详细的碳交换测量正在进行中。如果研究成功，我们将获得数据，整合树木生理学、遥感、林业和生物识别等方面的知识，更好地预测冠层结构对树木对气候和环境变化的生理反应的影响。最终将提高国家尺度和全球尺度森林碳积累模型的准确性和精密度。

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.
