Society relies on mathematical descriptions of climate change, weather forecasting, crop performance, and other processes in which the control of carbon uptake and water loss by plants forms a basic element. Scientists also use the same element in ascribing sources and sinks of carbon dioxide (CO2), describing vegetation, hydrological and ecological processes. A key physiological assumption in this element is now in doubt and we will test it rigorously and if necessary provide a robust alternative. We will do this by developing a novel 'window' on intact leaf functioning that will reveal the concentration of water vapour and other gases inside leaves.

社会依赖于对气候变化、天气预报、作物性能和其他过程的数学描述，在这些过程中，植物对碳吸收和水分流失的控制是一个基本要素。科学家们还使用相同的元素来描述二氧化碳的来源和汇，描述植被、水文和生态过程。这个因素的一个关键的生理假设现在是有疑问的，我们将严格测试它，如果必要的话，提供一个强有力的替代方案。我们将通过开发一种全新的“窗口”来研究完整的叶片功能，从而揭示叶片内水蒸气和其他气体的浓度。
