Detection of Local Mixing in Time-Series Data Using Permutation Entropy
Michael Neuder, Elizabeth Bradley, Edward Dlugokencky +2
While it is tempting in experimental practice to seek as high a data rate as possible, oversampling can become an issue if one takes measurements too densely. These effects can tak…

Anomaly Detection in Paleoclimate Records using Permutation Entropy
Joshua Garland, Tyler R. Jones, Michael Neuder +3
Permutation entropy techniques can be useful in identifying anomalies in paleoclimate data records, including noise, outliers, and post-processing issues. We demonstrate this using…

Climate entropy production recorded in a deep Antarctic ice core
Joshua Garland, Tyler R. Jones, Elizabeth Bradley +2
Paleoclimate records are extremely rich sources of information about the past history of the Earth system. Information theory, the branch of mathematics capable of quantifying the…
