PyCO2SYS

Tests pypi badge Conda Version DOI Docs Coverage License: GPL v3 Code style: black

Public beta testing for PyCO2SYS v2 is now live!

See the v2 docs at mvdh.xyz/PyCO2SYS for instructions and please provide feedback!

Introduction

PyCO2SYS is a Python implementation of CO2SYS, based on the MATLAB v2.0.5 but also including the updates made for MATLAB CO2SYS v3 as well as some additional related calculations. PyCO2SYS solves the full marine carbonate system from the values of any two of its parameters.

Every combination of input parameters has been tested, with differences in the results small enough to be attributable to floating point errors and iterative solver endpoint differences (i.e. negligible). See the scripts in validate to see how and check this for yourself, and their discussion in the online docs. Please let us know ASAP if you discover a discrepancy that we have not spotted!

Documentation is available online at PyCO2SYS.readthedocs.io.

There are also some usage examples that you can either download or run live in your web browser (with no Python installation required) at PyCO2SYS-examples.

Citation

A paper describing PyCO2SYS is freely available:

Humphreys, M. P., Lewis, E. R., Sharp, J. D., and Pierrot, D. (2022). PyCO2SYS v1.8: marine carbonate system calculations in Python. Geoscientific Model Development 15, 15-43. doi:10.5194/gmd-15-15-2022.

Please also specify the full version number that you used. You can find this in Python with:

python import PyCO2SYS as pyco2 pyco2.hello()

As per the instructions in the the CO2SYS-MATLAB repo, you should also consider citing the original work by Lewis and Wallace (1998).

Installation

If you manage Python with conda, we recommend that you first install NumPy, pandas and xarray into the environment where PyCO2SYS is to be installed with conda.

With pip

Install from the Python Package Index:

pip install PyCO2SYS

Update an existing installation:

pip install PyCO2SYS --upgrade --no-cache-dir

With conda/mamba

Install from the conda-forge channel:

conda install PyCO2SYS -c conda-forge

Documentation

Documentation for the current release, based on the main branch, is available at PyCO2SYS.readthedocs.io and at mvdh.xyz/PyCO2SYS.

Basic use

The only function you need is pyco2.sys. To solve the marine carbonate system from two of its parameters (par1 and par2), just use:

python import PyCO2SYS as pyco2 results = pyco2.sys(par1, par2, par1_type, par2_type, **kwargs)

The keys to the results dict are described in the documentation. Arguments should be provided as scalars or NumPy arrays in any mutually broadcastable combination. A large number of optional kwargs can be provided to specify everything beyond the carbonate system parameters — read the docs!.

You can also look at the examples Notebooks that you can try out without needing to install anything on your computer.
