Understanding how climatic factors affect ecosystem carbon dioxide and water fluxes is essential for better climate models and managements strategies. This project will use novel isotope laser spectroscopy to measure the oxygen isotope of transpired water and that of the atmosphere to examine carbon dioxide and water at both the leaf and ecosystem scale.

了解气候因素如何影响生态系统的二氧化碳和水通量，对于更好的气候模型和管理策略至关重要。该项目将使用新的同位素激光光谱学来测量蒸腾水和大气的氧同位素，以在树叶和生态系统的尺度上检查二氧化碳和水。
