Paper Review: Ogle (2019). SAM. CHANCE
· β˜• 3 min read · ✍️ Hoontaek Lee
15 February, 2020 (Ogle, CHANCE, SAM) Kiona Ogle & Jarrett J. Barber (2016) Plant and Ecosystem Memory, CHANCE, 29:2, 16-22, DOI: 10.1080/09332480.2016.1181961 Why did I read this paper? It is often easier to get knowledge (i.e., model, concept, equation, and so forth) not from the original descriptive paper, but from other papers using the knowledge because they introduce the knowledge after masticating it, not as it is. This paper masticates the stochastic antecedent modelling (SAM) framework for beginners.

Nature 541, 516-520 (2017). https://doi.org/10.1038/nature20780 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.
