pyleoclim 0.7.2

A Python package for paleoclimate data analysis

Python Package for the Analysis of Paleoclimate Data

Paleoclimate data, whether from observations or model simulations, offer unique challenges to the analyst. Pyleoclim is a Python package primarily geared towards the analysis and visualization of paleoclimate data. Such data usually come in the form of timeseries with missing values and age uncertainties, so the package includes several low-level methods to deal with these issues to simplify the user's life, with intuitive, high-level analysis and plotting methods that support publication-quality scientific workflows.

There are many entry points to Pyleoclim, thanks to its underlying data structures. The package makes use of the Linked Paleo Data (LiPD) standard container and its associated utilities. The package is aware of age ensembles stored via LiPD and uses them for time-uncertain analyses, very much like GeoChronR.

LiPD, however, is not an obligatory entry point to Pyleoclim. Low-level modules are primarily based on NumPy arrays or Pandas dataframes, so Pyleoclim contains a lot of timeseries analysis code (e.g. spectral analysis, singular spectrum analysis, wavelet analysis, correlation analysis) that can apply to these more common types as well, including those generated by numerical models (via xarray). This makes the package suitable for rigorous model-data comparisons, like this one.

We've worked very hard to make Pyleoclim accessible to a wide variety of users, from establisher researchers to high-school students, and from seasoned Pythonistas to first-time programmers. A growing collection of workflows that use Pyleoclim are available as Jupyter notebooks on paleoBooks.

A series of training material is also available on paleoHackthon. You can run these training notebooks at any time in a myBinder environment. We also run training workshops several times a year. Follow us on our social media accounts for more information.
