A response to Antala et al. (2024): ‘Nonphotochemical quenching does not alter the relationship between sun-induced fluorescence and gross primary production under heatwave’

We appreciate Antala et al. (2024) for their critical assessment of our article titled ‘Heatwave breaks down the linearity between sun-induced fluorescence and gross primary production’ (Martini et al., 2022), and support their emphasis on the importance of understanding how nonphotochemical quenching (NPQ) modulates the relationship between sun-induced fluorescence (SIF) and gross primary production (GPP). However, we believe that their Correspondence may have overlooked several crucial aspects of our work and their conclusions are, at least partially, based on some misunderstandings. We address what we believe represents their major points of criticism and reinforce the results presented in Martini et al. (2022) by means of a new modelling analysis.

建模分析证实了 NPQ 饱和度对热浪期间 GPP-SIF 关系发散的作用

对 Antala 等 人（2024 年）的回应：“非光化学猝灭不会改变热浪下太阳诱导荧光与总初级生产之间的关系”

我们感谢 Antala 等 人。（2024 年），以表彰他们对我们题为“热浪打破太阳诱导荧光和总初级生产之间的线性关系”的文章的批判性评估（Martini et al.， 2022），并支持他们强调了解非光化学猝灭 （NPQ） 如何调节太阳诱导荧光 （SIF） 和总初级生产 （GPP） 之间的关系的重要性。然而，我们认为他们的通信可能忽略了我们工作的几个关键方面，他们的结论至少部分是基于一些误解。我们解决了我们认为代表了他们主要批评点的内容，并加强了 Martini 等 人提出的结果。（2022 年）通过新的建模分析。
