Nature Communications 11, Article number: 1415 (2020) Peer Nowack, Jakob Runge, Veronika Eyring & Joanna D. Haigh Article LINK Abstract Global climate models are central tools for understanding past and future climate change. The assessment of model skill, in turn, can benefit from modern data science approaches. Here we apply causal discovery algorithms to sea level pressure data from a large set of […]
Entropy 2020, 22(3), 360; https://doi.org/10.3390/e22030360 by Peishi Jiang and Praveen Kumar Abstract Complex systems arise as a result of the nonlinear interactions between components. In particular, the evolutionary dynamics of a multivariate system encodes the ways in which different variables interact with each other individually or in groups. One fundamental question that remains unanswered is: How do two non-overlapping […]

Water Resources Research, 56, e2019WR026398. https://doi.org/10.1029/2019WR026398 Abstract The basis for all knowledge is “information” that we compile about the world, expressed through models that support understanding, prediction, and decision making. This overview paper provides a contextual basis for the four papers that make up […]
Nearing, G. S., Ruddell, B. L., Bennett, A. R., Prieto, C., & Gupta, H. V. (2020). Does information theory provide a new paradigm for earth science? Hypothesis testing. Water Resources Research, 56, e2019WR024918. https://doi.org/10.1029/2019WR024918 Abstract Model evaluation and hypothesis testing are fundamental to any field of science. We propose here that by changing slightly the way we […]
