Question:
How have machine learning algorithms, especially deep learning, been applied to Earth system science and what is the future direction of the application? Context:
Our ability to produce a deluge of data outpaces our ability to assimilate the information.

Question:
How do changes in temperature and water availability effect on gross primary productivity (GPP), terrestrial ecosystem respiration (TER), and net ecosystem exchange (NEE) at local and global scales? Context:
Despite temperature is known to contribute to the inter annual variation (IAV) of the terrestrial carbon cycle, several studies propose that water availability play an important role in the carbon cycle relates such as the carbon balance of semi-tropics and the sensitivity to IAV.

Why do a PhD? I like to do the PhD-related activities. Studying Working in nature Analyzing and computing Writing Presenting Educating I want to learn the ecosystem modeling at a deep level. I like the liberal atmosphere of academic community. Open discussion Less strict working time I like jobs with a PhD than ones with a bachelor’s or Master’s degree. Why do a PhD abroad? There are potential advisors whose
21 January, 2020 (Brugnera, GCB, Liana) di Porcia e Brugnera, M, Meunier, F, Longo, M, et al. Modeling the impact of liana infestation on the demography and carbon cycle of tropical forests. Global Change Biology, 2019; 25: 3767β 3780. https://doi.org/10.1111/gcb.14769
Question:
How much does integrating lianas into the ED2 influence the estimates of forest carbon cycle? The authors hypothesized that the impact of lianas on carbon uptake by forest would be larger in the secondary forests than in the old-growth forests since lianas showed high density in young forests.
