Abstract With climate extremes’ rising frequency and intensity, robust analytical tools are crucial to predict their impacts on terrestrial ecosystems. Machine learning techniques show promise but require well-structured, high-quality, curated analysis-ready datasets. Earth observation datasets comprehensively monitor ecosystem dynamics responses climatic extremes, yet the data complexity can challenge effectiveness of machine models. Despite recent progress in deep monitoring, there is a...
