Understanding leaf water isotope composition

该项目旨在量化叶水同位素的变化，并为古气候学家和植物科学家开发机制模型，以约束全球碳循环。叶水稳定同位素影响大气中氧、二氧化碳和水蒸气的同位素组成，并对植物有机物质的同位素组成产生蒸发信号。这些同位素信号已被用于限制全球碳和水循环，并重建过去的气候。该项目旨在量化叶水同位素的变化，并开发供古气候学家和植物科学家使用的机制模型，限制全球碳循环，并开发叶水同位素的准确模型，以减少气候模型的不确定性。

This project aims to quantify variation in leaf water isotopes and develop mechanistic models for paleoclimatologists and plant scientists to constrain global carbon cycles. Leaf water stable isotopes influence the isotope compositions of atmospheric oxygen, carbon dioxide and water vapour, and impart an evaporative signal on the isotope composition of plant organic material. These isotope signals have been used to constrain global carbon and water cycles and reconstruct past climates. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for use by paleoclimatologists, plant scientists and to constrain global carbon cycles and develop accurate models of leaf water isotopes to reduce uncertainty in climate models.
