Python Package for the Analysis of Paleoclimate Data

Table of contents

Current Version: 0.4.7

What is it?

Pyleoclim is a Python package primarily geared towards the analysis and visualization of paleoclimate data. Such data often 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, as well as high-level methods that re-use those within scientific workflows.

High-level modules assume that data are stored in the Linked Paleo Data (LiPD) format and makes extensive use of the LiPD utilities. 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. [need a link to some notebook examples]

The package is aware of age ensembles stored via LiPD and uses them for time-uncertain analyses very much like GeoChronR.

Current capabilities:

  • binning
  • interpolation
  • standardization
  • plotting maps, timeseries, and basic age model information
  • paleo-aware correlation analysis (isopersistent, isospectral and classical t-test)
  • weighted wavelet Z transform (WWZ)
  • age modelling through Bchron

Future capabilities:

  • paleo-aware singular spectrum analysis (AR(1) null eigenvalue identification, missing data)
  • spectral analysis (Multi-Taper Method, Lomb-Scargle)
  • cross-wavelet analysis
  • index reconstruction
  • climate reconstruction
  • ensemble methods for most of the above

Pyleoclim is published through PyPi and easily installed via pip

pip install pyleoclim

Quickstart guide

  1. Open your command line application (Terminal or Command Prompt).

  2. Install with command: pip install pyleoclim

  3. Wait for installation to complete, then:

    3a. Import the package into your favorite Python environment (we recommend the use of Spyder, which comes standard with the Anaconda package)

    3b. Use Jupyter Notebook to go through the tutorial contained in the PyleoclimQuickstart.ipynb Notebook, which can be downloaded here.

  4. Help with functionalities can be found in the Documentation folder on here.
